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.
  • Use PPE, including filtration and eye protection, when handling dust or emptying dust/shaving containers.

Equipment-Specific Safety

Intro to Filament 3D Printing Class is required to use this tool.

No special PPE is required to use this tool.

Etiquette

Time booked for 3D printing in Skedda does not count against your weekly Asmbly hours. It is fine to book long blocks of time when printing large objects. It is fine for a print to continue while Asmbly is closed. Please only reserve the time you need, and if you finish early or realize you can't make use of your time, please cancel the remainder of your reservation.

If you come in for your scheduled time and a print has finished, feel free to move it and any filament on the machine to the table to the left of the enclosure.

If you are in the 3D printing area and see a print in progress that is obviously failing, it is a good idea to stop the print so that it stops wasting filament. Try to contact the person who has that printer booked in Skedda to let them know. Discourse is a good way to do that, if you don't already know them.

You may find a cut-off piece of filament still in the nozzle when you arrive. This is because the nozzle was cold when the previous user retrieved their filament and they didn't want to wait for it to heat up again. When you heat the nozzle for your own print, just unload the stub and discard it.

Use Case

Apollo, Hermes, and Sunwukong
All three printers

The Prusa XL is a good printer to produce small, medium, and large sized objects using up to 5 filaments. It supports many common filament types.


If you need to print in ABS, ASA, or other materials that print better enclosed, consider using the PolyPrinter 229. Warping or delamination may occur due to the higher shrinkage of these materials.

Use Skedda to reserve time on the specific printer.

Materials

Acceptable Materials

Many types of 1.75mm filament will work with these printers.

This printer have been equipped with abrasion-resistant nozzle ONLY on nozzle 1 (ObXidian nozzles). This means that filaments that include additives like glow-in-the-dark (strontium aluminate), carbon fiber, glass fiber, wood, or metal are acceptable to use with this nozzle.

Material Limits

Print volume is 360mm x 360mm x 3600mm (14.1" x 14.1" x 14.1")

Consumables

You are responsible for providing your own filament. Please write your name on your filament spools. There are metallic sharpies available in the tool caddy.

There are many places to order from, including MatterHackers, Prusa, Polymaker, and Amazon. We are not currently aware of any place to buy filament locally, but if you know of one, we'd be interested!

There are some SD cards in the tool caddy, but if you find yourself printing from SD frequently, consider bringing your own. Files on the Asmbly SD cards are erased periodically to ensure there is enough space for everyone to use.

Asmbly provides a selection of Prusa steel sheets in three different textures: Textured, Satin, and Smooth. Asmbly also provides cleaners for the sheets: Isopropyl Alcohol (usually in a squeeze bottle with the printer tools) and Dish Soap (in the coffee area just outside of the multi-purpose room.

Operation

Controls

Emergency Stop

If you see or hear something going terribly wrong with the printer, you can immediately stop it by pressing the RESET button below the dial control. This is equivalent to unplugging the printer and plugging it back in. Examples of situations where you would want to do this: the nozzle is contacting the steel plate, the printer is trying to move the head beyond its rails.

If you just need to stop a print, please press the dial control and select Stop Print. The RESET button sometimes causes the printer to lose some of its settings and need to be recalibrated, so avoid using it for things you can stop normally. But if you are in doubt, do use the RESET button.

Control Panel

Each printer has a control panel that can be used to do things like preheating the machine, loading and unloading filament, pausing/stopping a print, and starting a print from an SD card.

PrusaLink

This printer is also equipped with a dedicated PrusaLink server:

Login information: The username is "maker", and the password is BcdhPrsUYS7EFz5.

PrusaLink allows you connect from the Asmbly WiFi network with a web browser or an app and start/stop a print and monitor things like the current temperature. You can't access these machines from home, you must be physically present at Asmbly.

Stopping or Pausing a print

You can stop a print from either PrusaLink or the control panel. If you stop or pause a print from PrusaLink, it will not move the nozzle clear of your print. If you hope to resume, it is probably better to do this from the control panel.

Firmware Upgrade Warning

Please contact a steward should a firmware upgrade message appear, or ignore the message if no stewards are present.

Settings and Adjustments

Filament

Make sure that your gcode is sliced for the particular kind of filament you're using. You can select the filament type on the control panel, and adjust the bed and nozzle temperatures.

Print Bed Sheet

🛑 DO NOT PRINT DIRECTLY ON THE BED. ALWAYS USE A STEEL SHEET.

Calibrated for Smooth1

Asmbly provides three different kinds of Prusa sheets:

There is a chart on the enclosure that lists which sheets are best for each kind of filament, or check Section 6.1 of the XL manual [2].

Ensure that the printer knows which sheet is on it. The sheets have different thicknesses, and you may not get a good first layer if the wrong sheet is selected.

Nozzles / Hotend

Nozzle 1 is equipped with the 0.4mm abrasion-resistance ObXidian nozzles.

The other nozzles are equipped with Nextruder 0.4mm nozzles.

Please do not change the nozzles.

Cleanup

Universal Cleaning Guide

  • Return the equipment to neutral.
  • Sweep up any dust and debris around the tool, your table top, and the floor - both in the equipment area and your work area.
  • Clear the floor of any tripping hazards, like power cords.
  • Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster behind the workshop.
  • Leave the shop 110% better than you found it.

Tool Specific Cleaning Guide

  • Remove any scraps of filament from the enclosure
  • Return any tools you used to the tool caddy
  • Make sure the steel sheet you used is clear of any leftover filament

Troubleshooting

Common Problems

Model not sticking to the sheet

If you are having trouble with getting your first layer to stick properly try these:

  1. Double check that the printer is configured for the right sheet
  2. Clean the cool sheet with Isopropyl Alcohol (in a squeeze bottle with the other tools)
  3. Wash the sheet with dish soap at the coffee area sink. Make sure the sheet is completely dry before reinstalling it.
  4. Contact a steward
Nozzle has plastic stuck to it

This often happens as a result of the model not sticking to the sheet, and causes problems when you try again.

⚠️ The nozzle is probably very hot! Don't touch it with something that will burn... like your fingers!


  1. Use Settings > Move axis > Move Z to raise the nozzle so you can see under it
  2. Touch some cool plastic to the still-hot plastic on the nozzle. It should stick and let you pull the mess away
  3. Heat the nozzle above the printing temperature for your filament, for example, try 250° for PLA, which normally prints around 215°. Wait for the nozzle to heat up and let the melted plastic drip off of the nozzle
  4. Use the tweezers from the tool caddy to grab larger lumps
  5. Use the soft-bristled brush in the tool caddy to wipe the warm nozzle
Other

If you are unsure, it is always best to contact a steward and fill out a problem report

Maintenance

The information below is primarily for stewards.

Regular Maintenance

The lead screws should be cleaned and lubricated regularly. This video provides a good walkthrough: How To Service Your Prusa i3 MK3

Moving the printers

The Prusa XL printer is located on top of a sliding platform. Take care when moving, as the printer is heavy (55 lbs).

Rebooting Procedure

Then toggle the power supply unit switch off and on.

Z Problems

In general, the Prusa XL does not require Z calibration. If the printer is printing too far away or too close to the bed for the first layer, check the following:

  1. Make sure the printer knows which sheet is on the bed. Different sheets have different calibration.
  2. If problems persist, please file a problem report or contact a steward.
