Setup of your personal copy of Lightburn
Lightburn is a very reasonably priced annual subscription and often used by members as their own CAD software for their designs. A member's LB installation is not to be used to control Tarkin directly, but create project files to load into Asmbly's workstation
It is cross-platform and has Windows, iOS, and Linux versions. There is a fully capable 30-day-limit trial version.
After installation, Lightburn asks which machine you have. It is sufficient to simply enter "Ruida" and bed size 1640x1000
However, a better alternative would be to download the current Tarkin machine profile here [TBD] and load that on to your machine on startup, or add under the Laser Panel->Devices. LB will create a copy of the machine profile file in its own directory so the file you pointed to is no longer necessary and can be moved. This has all the parameters that will allow you to get accurate time predictions in the Preview window. The machine parameters may be updated periodically so be sure you have the latest file
A Lightburn Material Database for Tarkin's material settings ready to install on your machine is located here [TBD: add '$wgFileExtensions = array( "clb", lbset" );' to LocalSettings.php]
There is a very useful class of single-line fonts called SHX that are free but not included with the standard download. Instructions to install are included here: https://forum.lightburnsoftware.com/t/shx-font-collection/25298
