== Safety ==

=== Universal Safety ===
* Be aware of your surroundings, especially when handling large materials.
* Do not approach anyone operating equipment. Stand patiently in their field of view.
* Safety glasses and closed-toed shoes are required in the shop.

=== Equipment-Specific Safety ===
[[Big Lasers Class]] is required to use this tool.

* '''Never leave the laser while it is running.''' Fires can start in seconds. You are responsible for the machine at all times during your job.
* Locate the HALOTRON fire extinguishers in the laser room before starting any work.
* The chiller must be on and running before any cutting. The laser will not fire without coolant flow.
* Keep the lid closed while the laser is running.
* Do not laser prohibited materials — some produce toxic or corrosive fumes and can permanently damage the machine.

== Use Case ==
Dorian is used for laser cutting, engraving, and rastering. Its 150W power and large 36"×51" bed make it well-suited for production runs and larger material sheets. The rotary fixture enables engraving of cylindrical objects. It operates with Lightburn, similar to Tarkin, so users comfortable with Tarkin will find Dorian familiar.

== Materials ==

=== Acceptable Materials ===
Before starting any job, verify your material is laser-safe on the [[Laser Cutter Materials]] page. Common safe materials include: acrylic, plywood, wood, MDF, cardboard, leather, paper, fabric.

=== Prohibited Materials ===
* '''PVC / Vinyl''' — releases corrosive chlorine gas. Do not attempt.
* '''Polycarbonate / Lexan''' — looks like acrylic but does not cut, damages the laser.
* '''PTFE / Teflon''' — produces toxic and corrosive gases.
* '''Epoxy''' — not laser-safe.
* '''Materials with sticky glue backing''' — glue residue requires lens replacement.
* '''Polystyrene and Polypropylene''' — catch fire and make a mess.
* '''Metal''' — contact workshop before attempting.
* '''Food''' — contamination risk.

When in doubt, use the copper wire flame test for chlorine (PVC) detection.

=== Consumables ===
Check the [[Laser Cutter Materials]] page for settings by material.

== Setup ==

=== 1. Locate Fire Extinguishers ===
Identify the HALOTRON extinguishers in the laser room before starting work.

=== 2. Power On ===
Turn on the laser using the black knob on the right side of the machine. If the light doesn't come on, twist the red knob — if the E-stop was used to power down, the red knob will have popped up and must be reset.

=== 3. Turn On Chiller ===
The machine will not cut without the chiller running. Turn it on and confirm it reaches operating temperature before starting your job.

=== 4. Reboot the PC (Recommended) ===
Consider rebooting the laser room PC before starting your project. This clears any settings changed by previous users and returns Lightburn to a default state.

=== 5. Verify Artwork Size ===
Open your file in Lightburn and verify the size of your artwork before doing anything else. Files can import at the wrong scale depending on file type and originating software.

=== 6. Focus the Laser ===
Focus the laser every time you place a new sheet of material on the bed. Consult the Lightburn documentation or ask a steward if you are unsure of the focus procedure for Dorian.

=== 7. Set Origin ===
Verify your desired origin settings in Lightburn before sending. If the laser moves somewhere unexpected when you frame your job, the origin settings are likely the cause. See [[Tarkin]] for an explanation of Absolute vs. User Origin modes — Dorian uses the same Ruida-based system.

=== 8. Pre-Job Checklist ===
Before pressing Start, confirm:
* Inner cuts are on top layers (so they cut first, before outer cuts free the piece).
* Check job runtime in Lightburn Preview — ensure it fits within your reservation.
* Material is flat, secured to the bed, and parallel to the gantry.
* Laser head will not collide with material hold-downs or clamps.
* You have done a small test cut on a scrap of the same material.
* You have confirmed your origin and framed the artwork.

=== 9. Enable Rotary Fixture (if applicable) ===
Enable the rotary fixture option in Lightburn settings if using the rotary attachment. Disable it for all flat-bed jobs.

=== 10. Run Your Job ===
Press Start. Monitor the machine for the entire duration of the job. Use Pause to stop without losing your job if you need a brief moment, but do not leave the machine unattended.

== Cleanup ==

=== Universal Cleaning Guide ===
* Return the equipment to neutral.
* Sweep up debris around the tool, your table, and the floor.
* Clear the floor of tripping hazards such as power cords.
* Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster.
* Leave the shop 110% better than you found it.

=== Tool-Specific Cleaning Guide ===
# Clean debris from the bed — vacuum small pieces rather than letting them fall into the honeycomb.
# Wipe down the interior of the machine.
# Turn off the laser and chiller. Order does not matter.
# Return all accessories (rotary fixture, jigs, clamps) to their storage locations.
# Ensure the floor area around the machine is clean and dry.

Pearl

2026-03-08T04:49:48Z

NickE:

{{Required|Small Lasers}}
Pearl is a Royal Mark RSX-1832 laser cutter. It shares the same chassis as [[Blue]] (it even has ULS badges on the back) but runs at 100W — slightly more powerful than Blue — and a rotary fixture for engraving round objects like glassware.

{{ToolPhoto|PearlLaser.jpg}}

== Specifications ==
{| class="wikitable"
|-
! Laser Type || CO2
|-
! Power || 100W
|-
! Bed Size || 32" × 18" (approximate)
|-
! Controller || ULS-compatible
|-
! Software || ULS Print Driver (prints from CorelDraw, Inkscape, Illustrator, etc.)
|-
! Z Axis || Powered (manual focus adjustment via stick)
|-
! Air Assist || Yes (not functional as of October 2021 — check current status)
|-
! Rotary Fixture || Yes
|-
! Location || Laser room
|}

== Safety ==

=== Universal Safety ===
* Be aware of your surroundings, especially when handling large materials.
* Do not approach anyone operating equipment. Stand patiently in their field of view.
* Safety glasses and closed-toed shoes are required in the shop.

=== Equipment-Specific Safety ===
[[Small Lasers Class]] is required to use this tool.

* '''Never leave the laser while it is running.''' Fires can start in seconds.
* Locate the HALOTRON fire extinguishers in the laser room before starting.
* The chiller must be running at all times when the laser is on. If the red light on the control panel is flashing, the lid is open or the chiller is off — do not operate.
* The CO2 laser beam is invisible infrared. The polycarbonate lid blocks it, so keep the lid closed during operation.
* Do not press the white focus button on the machine or adjust focus in software — these settings are calibrated by authorized personnel and are not user-adjustable. Changing them affects all subsequent users.

== Use Case ==
Pearl is used for laser cutting, engraving, and rastering. Its rotary fixture makes it the go-to machine for engraving cylindrical objects (glasses, bottles, pens). It cuts faster and cleaner than Blue due to its higher power.

== Materials ==

=== Acceptable Materials ===
Check the [[Laser Cutter Materials]] page before working with any material you haven't used before. Common safe materials include: acrylic, plywood, wood, MDF, cardboard, leather, paper, fabric.

Pearl's bed size is 32"×18". Set your artboard to this size when preparing artwork.

=== Prohibited Materials ===
* '''PVC / Vinyl''' — releases corrosive chlorine gas.
* '''Polycarbonate / Lexan''' — does not cut cleanly, produces heavy soot that fouls optics.
* '''PTFE / Teflon''' — produces toxic and corrosive gases.
* '''Metal''' — contact workshop before attempting.
* '''Food''' — contamination risk.
* '''Materials with sticky glue backing''' — glue residue cannot be removed without risking lens damage.
* '''Epoxy''' — not laser-safe.
* '''Polystyrene and Polypropylene''' — catch fire and make a mess.

=== Recommended Settings ===
* 1/8" plywood: 11% speed, 150 PPI
* 0.2" plywood: 8% speed, 150 PPI
* For cutting: 150 PPI is a good starting point.
* For rastering/engraving: 500 PPI suggested.

== Setup ==

=== 1. Turn On Chiller ===
Turn on the chiller. Wait for it to reach 20°C (or whatever temperature is labeled above the display) — this takes under 5 minutes. The chiller will auto-regulate. Do not run the machine if the chiller is not at temperature.

Turn on the exhaust blower (currently a switch on a power strip). Do not run the laser without the blower on.

=== 2. Set Machine Origin ===
This step is required each time the machine is powered on.

# Press the '''X-Y''' button to enter jog mode.
# Use the arrow keys to jog to the top-left of the bed. The LCD should read '''POS 0.000x 0.000y''' on the second line.
# The cursor should be on '''SET NEW ORIGIN''' — press '''SELECT''', confirm the prompt. The display should now also show '''ORG 0x 0y''' on the first line.

[[File:PXL_20211109_061933365_(1).jpg|center|thumb]]

The LCD should read '''ORG 0x 0y''' on the first line and '''POS 0.000x 0.000y''' on the second:

[[File:PXL_20211109_061947068_(2).jpg|center|thumb]]

=== 3. Set Z Height (Focus) ===
Pearl has a powered Z axis but it does not move automatically — you set it manually for each sheet of material.

# Press the '''Z''' button on the right once. The carriage will move to a focus position.
[[File:Pearl_move_z.jpg|center|thumb]]
# Place your stock on the bed under the carriage.
# Locate the '''focus stick''' (stored in a hole on the left of the bed under the lid).
[[File:Pearl_focus_stick.jpg|center]]
# Place the focus stick on top of your stock, against the '''front of the carriage''' (not the side). The ramp on the stick is the measurement point — it contacts the bottom lip of the front of the carriage at the correct focal distance.
[[File:Pearl_stick_on_stock.jpg|center|thumb|Focus stick placed on stock — this is shown LOW, you need to Z UP.]]
# Use '''Z UP/DOWN''' arrows to move the bed. The Z position LCD display is not reliable — just use the stick.
[[File:Pearl_z_display.jpg|center|thumb]]
# If the ramp tilts the stick away, the bed is too high — go DOWN:
[[File:Pearl_z_high.jpg|center|thumb|Too high — the ramp tilts the stick away. Go DOWN.]]
# When the stick sits correctly against the carriage front, you're at the right height:
[[File:Pearl_Z_perfect.jpg|center|thumb|Perfect focus.]]
# Press the '''Z''' button a second time to send the carriage home and return the stick to its hole.
[[File:Pearl_stick.jpg|center|thumb|The official ULS manual diagram]]

==== Updated Focus Tool ====
There is a newer 3D-printed focus tool that form-fits the carriage front — clearer to use than the original stick. This is also the correct tool for '''rotary use''', as the foot aligns inline with the laser focal point and the top of the work on the rotary chuck.

[[File:PXL_20230816_040933344.jpg|thumb|Updated 3D-printed focus tool]]

'''Warning:''' Do not power off the machine with the bed jogged all the way down. Jog it up at least 0.5" first or the firmware will be confused on next startup. (See Z-Bottom Recovery in Troubleshooting if this happens.)

=== 4. Prepare Your File ===
Pearl uses the ULS print driver. Send your job by printing from CorelDraw, Inkscape, Illustrator, or another supported application.

'''For Illustrator users:'''
* Change stroke units to inches: Edit → Preferences → Units → Stroke = Inches
* Set all vector lines to 0.001" stroke width (hairline). Thicker lines are interpreted as raster.
* Print settings: Media size = DEFINED BY DRIVER; Orientation = '''PORTRAIT''' (Illustrator may reset this to Landscape when you visit Setup — recheck each time); Placement = CENTER, X=0, Y=0; Scaling = DO NOT SCALE.
* Verify in Preview before sending.

[[File:Pearl_illustrator.jpg|center|frameless|Illustrator print settings example]]

In the ULS Setup window, set speed, power, PPI, and rastering settings.

[[File:Pearl_print_driver.jpg|center|thumb|ULS print driver settings — note there is no Z entry (Pearl runs wherever you left it after the stick)]] Pearl does not have a Z setting in the driver (unlike Red/Blue) — it runs wherever the Z was left after your manual focus adjustment.

=== 5. Enable Rotary Fixture (if applicable) ===
If using the rotary fixture, enable '''ROTARY ENABLED''' on page 2 of the print driver settings. Ensure it is unchecked for all non-rotary jobs.

=== 6. Send Job and Run ===
Send the job from your application. Press START on the machine.

If you hear '''two beeps''' immediately, the job is empty. Check: origin is set to 0x 0y, Orientation is Portrait, vector lines are 0.001" stroke, Rotary Enabled is off (if not a rotary job).

If the '''red light is flashing''': chiller is off or lid is open.

== Cleanup ==

=== Universal Cleaning Guide ===
* Return the equipment to neutral.
* Sweep up debris around the tool, your table, and the floor.
* Clear the floor of tripping hazards such as power cords.
* Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster.
* Leave the shop 110% better than you found it.

=== Tool-Specific Cleaning Guide ===
# Remove small debris from the honeycomb — vacuum rather than brushing into it.
# Wipe down the interior of the machine if needed.
# Turn off the machine, chiller, and exhaust blower. Order does not matter.
# Return the focus stick to its storage hole.
# Replace the honeycomb if removed.

== Safety ==

=== Universal Safety ===
* Be aware of your surroundings, especially when handling large materials.
* Do not approach anyone operating equipment. Stand patiently in their field of view.
* Safety glasses and closed-toed shoes are required in the shop.

=== Equipment-Specific Safety ===
[[Small Lasers Class]] is required to use this tool.

* '''Never leave the laser while it is running.''' Fires can start in seconds.
* Locate the HALOTRON fire extinguishers in the laser room before starting.
* The chiller must be running at all times when the laser is on. If the red light on the control panel is flashing, the lid is open or the chiller is off — do not operate.
* The CO2 laser beam is invisible infrared. The polycarbonate lid blocks it, so keep the lid closed during operation.
* Do not press the white focus button on the machine or adjust focus in software — these settings are calibrated by authorized personnel and are not user-adjustable. Changing them affects all subsequent users.

== Use Case ==
Pearl is used for laser cutting, engraving, and rastering. Its rotary fixture makes it the go-to machine for engraving cylindrical objects (glasses, bottles, pens). It cuts faster and cleaner than Blue due to its higher power.

== Materials ==

=== Acceptable Materials ===
Check the [[Laser Cutter Materials]] page before working with any material you haven't used before. Common safe materials include: acrylic, plywood, wood, MDF, cardboard, leather, paper, fabric.

Pearl's bed size is 32"×18". Set your artboard to this size when preparing artwork.

=== Prohibited Materials ===
* '''PVC / Vinyl''' — releases corrosive chlorine gas.
* '''Polycarbonate / Lexan''' — does not cut cleanly, produces heavy soot that fouls optics.
* '''PTFE / Teflon''' — produces toxic and corrosive gases.
* '''Metal''' — contact workshop before attempting.
* '''Food''' — contamination risk.
* '''Materials with sticky glue backing''' — glue residue cannot be removed without risking lens damage.
* '''Epoxy''' — not laser-safe.
* '''Polystyrene and Polypropylene''' — catch fire and make a mess.

=== Recommended Settings ===
* 1/8" plywood: 11% speed, 150 PPI
* 0.2" plywood: 8% speed, 150 PPI
* For cutting: 150 PPI is a good starting point.
* For rastering/engraving: 500 PPI suggested.

== Setup ==

=== 1. Turn On Chiller ===
Turn on the chiller. Wait for it to reach 20°C (or whatever temperature is labeled above the display) — this takes under 5 minutes. The chiller will auto-regulate. Do not run the machine if the chiller is not at temperature.

Turn on the exhaust blower (currently a switch on a power strip). Do not run the laser without the blower on.

=== 2. Set Machine Origin ===
This step is required each time the machine is powered on.

# Press the '''X-Y''' button to enter jog mode.
# Use the arrow keys to jog to the top-left of the bed. The LCD should read '''POS 0.000x 0.000y''' on the second line.
# The cursor should be on '''SET NEW ORIGIN''' — press '''SELECT''', confirm the prompt. The display should now also show '''ORG 0x 0y''' on the first line.

[[File:PXL_20211109_061933365_(1).jpg|center|thumb]]

The LCD should read '''ORG 0x 0y''' on the first line and '''POS 0.000x 0.000y''' on the second:

[[File:PXL_20211109_061947068_(2).jpg|center|thumb]]

=== 3. Set Z Height (Focus) ===
Pearl has a powered Z axis but it does not move automatically — you set it manually for each sheet of material.

# Press the '''Z''' button on the right once. The carriage will move to a focus position.
[[File:Pearl_move_z.jpg|center|thumb]]
# Place your stock on the bed under the carriage.
# Locate the '''focus stick''' (stored in a hole on the left of the bed under the lid).
[[File:Pearl_focus_stick.jpg|center]]
# Place the focus stick on top of your stock, against the '''front of the carriage''' (not the side). The ramp on the stick is the measurement point — it contacts the bottom lip of the front of the carriage at the correct focal distance.
[[File:Pearl_stick_on_stock.jpg|center|thumb|Focus stick placed on stock — this is shown LOW, you need to Z UP.]]
# Use '''Z UP/DOWN''' arrows to move the bed. The Z position LCD display is not reliable — just use the stick.
[[File:Pearl_z_display.jpg|center|thumb]]
# If the ramp tilts the stick away, the bed is too high — go DOWN:
[[File:Pearl_z_high.jpg|center|thumb|Too high — the ramp tilts the stick away. Go DOWN.]]
# When the stick sits correctly against the carriage front, you're at the right height:
[[File:Pearl_Z_perfect.jpg|center|thumb|Perfect focus.]]
# Press the '''Z''' button a second time to send the carriage home and return the stick to its hole.
[[File:Pearl_stick.jpg|center|thumb|The official ULS manual diagram]]

==== Updated Focus Tool ====
There is a newer 3D-printed focus tool that form-fits the carriage front — clearer to use than the original stick. This is also the correct tool for '''rotary use''', as the foot aligns inline with the laser focal point and the top of the work on the rotary chuck.

[[File:PXL_20230816_040933344.jpg|thumb|Updated 3D-printed focus tool]]

'''Warning:''' Do not power off the machine with the bed jogged all the way down. Jog it up at least 0.5" first or the firmware will be confused on next startup. (See Z-Bottom Recovery in Troubleshooting if this happens.)

=== 4. Prepare Your File ===
Pearl uses the ULS print driver. Send your job by printing from CorelDraw, Inkscape, Illustrator, or another supported application.

'''For Illustrator users:'''
* Change stroke units to inches: Edit → Preferences → Units → Stroke = Inches
* Set all vector lines to 0.001" stroke width (hairline). Thicker lines are interpreted as raster.
* Print settings: Media size = DEFINED BY DRIVER; Orientation = '''PORTRAIT''' (Illustrator may reset this to Landscape when you visit Setup — recheck each time); Placement = CENTER, X=0, Y=0; Scaling = DO NOT SCALE.
* Verify in Preview before sending.

[[File:Pearl_illustrator.jpg|center|frameless|Illustrator print settings example]]

In the ULS Setup window, set speed, power, PPI, and rastering settings.

[[File:Pearl_print_driver.jpg|center|thumb|ULS print driver settings — note there is no Z entry (Pearl runs wherever you left it after the stick)]] Pearl does not have a Z setting in the driver (unlike Red/Blue) — it runs wherever the Z was left after your manual focus adjustment.

=== 5. Enable Rotary Fixture (if applicable) ===
If using the rotary fixture, enable '''ROTARY ENABLED''' on page 2 of the print driver settings. Ensure it is unchecked for all non-rotary jobs.

=== 6. Send Job and Run ===
Send the job from your application. Press START on the machine.

If you hear '''two beeps''' immediately, the job is empty. Check: origin is set to 0x 0y, Orientation is Portrait, vector lines are 0.001" stroke, Rotary Enabled is off (if not a rotary job).

If the '''red light is flashing''': chiller is off or lid is open.

== Cleanup ==

=== Universal Cleaning Guide ===
* Return the equipment to neutral.
* Sweep up debris around the tool, your table, and the floor.
* Clear the floor of tripping hazards such as power cords.
* Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster.
* Leave the shop 110% better than you found it.

=== Tool-Specific Cleaning Guide ===
# Remove small debris from the honeycomb — vacuum rather than brushing into it.
# Wipe down the interior of the machine if needed.
# Turn off the machine, chiller, and exhaust blower. Order does not matter.
# Return the focus stick to its storage hole.
# Replace the honeycomb if removed.

== Safety ==

=== Universal Safety ===
* Be aware of your surroundings, especially when handling large materials.
* Do not approach anyone operating equipment. Stand patiently in their field of view.
* Safety glasses and closed-toed shoes are required in the shop.

=== Equipment-Specific Safety ===
[[Small Lasers Class]] is required to use this tool.

* '''Never leave the laser while it is running.''' Fires can start in seconds.
* Locate the HALOTRON fire extinguishers in the laser room before starting any work.
* The CO2 laser beam is invisible infrared. The polycarbonate lid blocks IR light — keep it closed during operation. If the lid is not properly shut, the laser will cut off automatically (red light on control panel will flash).
* '''Do not press the white focus button on the machine or adjust focus in the software.''' Focus is calibrated by authorized personnel. Changing it affects all subsequent users.
* Do not operate the laser if the lens or mirrors appear dirty (dull, greyish-brown rather than golden-yellow). Fill out a [https://asmbly.org/problem problem report] by scanning one of the red QR codes in the space — this notifies the space stewards of the problem. Do not attempt to clean them without specific training — the optics are fragile and easily damaged.

== Use Case ==
Blue is used for laser cutting, engraving, and rastering of a wide variety of materials on a 32"×18" bed. It is a good general-purpose machine for smaller jobs. For larger-format work or higher power, consider [[Tarkin]] or [[Dorian]]. For engraving round objects, use [[Pearl]] (which has a rotary fixture). Trained Blue users may also use [[Pearl]], which is similar in operation.

== Materials ==

=== Acceptable Materials ===
Check the [[Laser Cutter Materials]] page before working with any material you haven't used before. Common safe materials include: acrylic, plywood, wood, MDF, cardboard, leather, paper, fabric, glass and stone (etch only).

Blue's bed size is 32"×18". Setting your artboard to this size in your design software makes placement easier.

=== Prohibited Materials ===
* '''PVC / Vinyl (including vinyl records)''' — 60% chlorine by weight; releases corrosive gas that destroys the machine. Do not attempt.
* '''Polycarbonate / Lexan''' — does not cut, produces heavy soot that fouls optics instantly. Includes CDs, DVDs, Blu-ray discs.
* '''PTFE / Teflon''' — produces toxic and corrosive gases.
* '''Metal''' — contact workshop before attempting.
* '''Food''' — contamination risk.
* '''Epoxy''' — not laser-safe.
* '''Materials with sticky glue backing''' — glue residue requires lens replacement.
* '''Polystyrene and Polypropylene''' — catch fire and make a mess.

When in doubt, use the copper wire flame test to check for chlorine: [https://www.youtube.com/results?search_query=laser+cutter+flame+test YouTube search]

=== Consumables ===
Check the [[Laser Cutter Materials]] page for settings. A [[Blue Laser Cutter Settings]] page with material-specific settings is also available.

== Setup ==

=== 1. Locate Fire Extinguishers ===
Identify the HALOTRON fire extinguishers in the laser room before starting work.

=== 2. Power On ===
Power on the machine. Ensure the lid is closed and the chiller (if applicable) is running. The red light on the control panel will flash if there is a problem (lid open, chiller off).

=== 3. Focus ===
Use the 3D-printed focus tool (labeled "Pearl" but works for both machines) to set focus. Align the focus tool to the screw on the laser head and adjust the Z-height to meet your material surface.

'''Do not use the white focus button on the machine or adjust focus in the software.''' These are calibrated by authorized personnel only.

=== 4. Prepare Your File ===

==== Color Conventions ====
Blue uses a color-based system to control laser operations:
* '''Red lines''' — cut all the way through
* '''Blue or green lines''' — etch (vector engrave)
* '''Grayscale images''' — raster (darker = more power)

Power, speed, raster/vector mode, PPI, and Z-depth can be set independently for each color (Black, Red, Green, Blue, Cyan, Magenta, Yellow). The laser processes colors in that order — useful for cutting small or springy parts after etching.

==== File Preparation ====
Make your drawing in CorelDraw or import an SVG from Inkscape. Vector lines must be '''hairline weight''' (0.001" or thinner) or they will be interpreted as raster fills.

Set your artboard to 32"×18" to match the machine bed.

==== For Illustrator Users ====
* Change stroke units to inches: Edit → Preferences → Units → Stroke = Inches
* Set all vector cut lines to 0.001" stroke width
* Print settings: Media size = DEFINED BY DRIVER; Orientation = '''PORTRAIT''' (recheck each time you visit Setup — Illustrator may reset this); Placement = CENTER, X=0, Y=0; Scaling = DO NOT SCALE
* Verify placement in the Preview window before sending

=== 5. Set Power and Speed ===
In the ULS Setup window, configure speed, power, and PPI per color layer. Refer to [[Laser Cutter Materials]] or [[Blue Laser Cutter Settings]] for tested values.

=== 6. Send Job and Run ===
Send the job from your design application. Confirm it appears correctly in the ULS control panel preview. Press Start. Monitor the machine for the entire duration of the job.

== Cleanup ==

=== Universal Cleaning Guide ===
* Return the equipment to neutral.
* Sweep up debris around the tool, your table, and the floor.
* Clear the floor of tripping hazards such as power cords.
* Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster.
* Leave the shop 110% better than you found it.

=== Tool-Specific Cleaning Guide ===
# Remove material scraps and debris from the bed and surrounding area.
# Vacuum small debris from inside the machine — avoid pushing debris into the honeycomb.
# Inspect the lens before and after your job. If it appears dull or greyish-brown (rather than golden-yellow), fill out a [https://asmbly.org/problem problem report] by scanning one of the red QR codes in the space. Do not operate with dirty optics.
# Power off the machine.
# Return the focus tool to its storage location.

|}

=== Dirty Optics ===
If the laser is cutting poorly, inspect the lens using the mirror and lamp kept on top of the machine. Carefully place the mirror onto the vector table underneath the cutting head and shine the lamp down onto it to illuminate the underside of the head:

[[File:InspectingLaser1.jpg|300px]]

When it's dirty, it looks dull and greyish-brown like this:

[[File:InspectingLaser2.png|300px]]

The lens should appear '''golden-yellow''' (the lens is coated with a thin layer of gold).

* Do not operate the laser with dirty optics at high power — heat from the dirt can permanently ruin the gold coating or crack the lens.
* Do not attempt to clean optics without specific training. The procedure is described in [[LaserCleaning|Cleaning the Laser Cutter]], but should not be undertaken without hands-on instruction — the optics are fragile and easily damaged.
* Fill out a [https://asmbly.org/problem problem report] by scanning one of the red QR codes in the space — this notifies the space stewards. Do not use the machine until cleared by authorized personnel.

[[File:DestroyedLaserLens.jpg|150px|A destroyed laser lens — this is what happens when dirty optics are used at high power.]]

When in doubt, contact a steward or [https://asmbly.org/problem submit a problem report].

=== Dirty Optics ===
If the laser is cutting poorly, inspect the lens using the mirror and lamp kept on top of the machine. Carefully place the mirror onto the vector table underneath the cutting head and shine the lamp down onto it to illuminate the underside of the head:

When it's dirty, it looks dull and greyish-brown like this:

[[File:InspectingLaser2.png|300px]]

The lens should appear '''golden-yellow''' (the lens is coated with a thin layer of gold).

* Do not operate the laser with dirty optics at high power — heat from the dirt can permanently ruin the gold coating or crack the lens.
* Do not attempt to clean optics without specific training. The procedure is described in [[LaserCleaning|Cleaning the Laser Cutter]], but should not be undertaken without hands-on instruction — the optics are fragile and easily damaged.
* Fill out a [https://asmbly.org/problem problem report] by scanning one of the red QR codes in the space — this notifies the space stewards. Do not use the machine until cleared by authorized personnel.

When in doubt, contact a steward or [https://asmbly.org/problem submit a problem report].

NickE:

Stewards are the volunteers who keep our space running! Machine maintenance, shop organization, space planning, and budgeting are all done by volunteer stewards.

Our Shop Stewards program was originally developed and led by Shop Supervisor Charlie Staley.

Each major area of the facility has a responsible individual who handles overall management, proposal reviews, work coordination, etc.

Area leads are listed here; the full stewards corps roster can be found [https://yo.asmbly.org/g/stewards in Discourse].

Grizzly G0569 Bandsaw

2025-01-10T21:39:56Z

NickE:

{{Required|Woodshop Safety}}

The Grizzly G0569 Resaw Bandsaw is along the wall in the [[:Category:Woodshop|woodshop]], next to the large [[Powermatic WB-37 Wide Belt Sander|Powermatic Belt Sander]].

{{ToolPhoto|G0569.jpg}}

[https://www.grizzly.com/products/grizzly-24-7-1-2-hp-3-phase-industrial-bandsaw/g0569 Grizzly G0569 - 24" 7-1/2 HP 3-Phase Industrial Bandsaw]

*Motor: 7.5 HP
*Max cutting width: 24-1/2 in.
*Max cutting height: 16-1/4 in.
*Table size: 33-1/2 in. x 23-5/8 in.
*Wheel type: Computer-Balanced Cast Iron
*Blade size: 181 in.

==Safety==

{{UniversalSafety}}

====Equipment-Specific Safety====

*Do not cut metal with this tool. This bandsaw is to be used for wood only.
*Only use this saw for resawing or straight cuts. No curves.
*No adjustments allowed, except for Fence & Cutting height. Do not adjust bearings or tension. Do not release tension.
*If you are cutting logs, you must use a fixture. You will have to build your own. You must also run a metal detector across logs.
*Check the blade before and after cutting for residue buildup from milling- this is easily cleaned.

For this saw, the brake pedal should be used as the primary "off button". Lightly pressing on the brake pedal will turn off power to the saw, however it will still take a little while for the blade to stop running. (This is per Grizzly Technical Support, and is not stated in their current version manual).

The red button on the power panel is the EMERGENCY off button. If you use this button, you will need to twist it to reset it. It will take the blade more than a minute to come to a stop after pressing the off button, the brake pedal can be used to bring the blade to a stop faster. Only stomp heavily on the brake pedal or use the red off button in an emergency.

==Use Case==

The Grizzly G0569 is used for [[wikipedia:Resaw|resawing]]. It can be used to rough cut lumber from logs, cut lumber into thinner segments, and even make your own veneers!

==Materials==

====Acceptable Materials====

Only wood should be cut on this bandsaw. If you are cutting raw logs, please use one of the metal detectors in the shop to double check the log for any metal. If you are cutting logs, you must use a fixture. You will have to build your own.

====Maximum Sizes and Weights====

*Max cutting width: 24-1/2 in.
*Max cutting height: 16-1/4 in.

====Consumables====

If the saw throat plate is damaged, please submit a problem report via the red QR code on the machine. Spare throat plates (if available currently) are stored in the bottom cabinet of one of the smaller bandsaws.

This saw takes a 180" blade. We typically equip it with a 1" 3tpi Timber Wolf resaw blade.
*No blade changes - If you notice a problem with the blade, please submit a problem report via the red QR code on the machine.

== Setup ==
Using this tool requires you to book time in [https://asmbly.skedda.com/booking Skedda] under "Woodshop - User 1-6" or another Woodshop slot.

=== 1. Ensure [[Laguna TFlux 5 Dust Collector |Dust Collection]] is Turned On ===
This bandsaw is attached to the main dust collector for the shop. Make sure that the main dust collector is on and functioning before using this tool.

=== 2. Set Cutting Height ===
Start by turning the screw wheel (Black, on the back of the machine) counter clockwise until loose to release the lock on the guide adjustment wheel (Silver, on the right side of the machine). Only move the guide adjustment wheel when it has been unlocked.

Once unlocked, rotate the guide adjustment wheel until the guide wheels are no higher than 1/4" above the piece you will be cutting.

=== 3. Set Fence depth ===
Adjust the fence by raising the lever on the front of the machine to loosen it, and lowering it to tighten the fence once set in the correct position. The fence likes to shift when being tightened down, so ensure it stays in the correct spot.

The cast-iron fence isn't super tall. We keep sacrificial MDF fences around to help with resawing taller material.

=== 4. Optional: Set Up Roller Stands ===
If you are cutting a piece of wood that is too large to be balanced on the table throughout the cut, please use one of the many roller stands to support your work both on the infeed and outfeed sides of the saw.

== Basic Operation ==

=== 1. Turn On Saw ===
Using the green power button, turn the saw on. If the saw does not start, check the following:
*The key must be turned to "on"
*The red emergency stop button must not be depressed (twist it to ensure this is the case)
*The foot brake should be lifted (a few mm of drop here can stop the saw from turning on, so even though it may look raised all the way it is often not)

=== 2. Align Workpiece With Fence ===
The wood you are cutting should be pressed up against the fence during the entire cut. There are featherboards hung on the wall next to the bandsaw, as well as magnetic fingerboards etc stored by the miter saw.

=== 3. Feed Workpiece Through Saw ===
While ensuring it stays in contact with the fence, very lightly feed the wood through the saw. There should be no discernable force required to do so- if you can feel that you are pushing *into* the sawblade you're cutting too fast. Take care not to push the workpiece around while feeding it to ensure an even and straight cut.

=== 4. Turn Saw off With Footbrake ===

For this saw, the brake pedal should be used as the primary "off button". Lightly pressing on the brake pedal will turn off power to the saw, however it will still take a little while for the blade to stop running. You can lightly press on the brake to speed up this process, but avoid stomping on the brake unless there is an emergency.

==Cleanup==

{{UniversalCleaning}}

====Tool Specific Cleaning Guide====

*Make sure the saw is turned off before cleaning
*Use a brush/broom (or vacuum) to clean off all exterior surfaces of the saw as well as the floor around it.
*Use a vacuum to clear the bottom "cabinet" of the saw of any sawdust built up throughout your use
*Check to see if residue has built up around the blade, rollers, or wheels. They are easily cleaned off using the Simple Green cleaning solution and a brush or blade scraper. (Scraper can be found at the tool wall, brushes are in the microjig cleaning bin).
*Check to see if the throat plate of the saw was damaged during operation- if so, please submit a problem report using the red QR code on the machine.
*Return any fingerboards etc to their rightful place within the shop.
