How to configure SCULPFUN S9 in LightBurn?

[berainlb (PY)]

The process of adding a laser is well described in the documentation:
Adding a Laser - LightBurn Software Documentation

In terms of size… there seems to be all sort of sizes listed. There is even a 3rd size based on the GRBL parameters in the S9 controller of 410x400.

You can check this other topic for background on this:

Sculpfun S9 workspace X,Y axis setup

These indicate what your laser controller believes is the worksize of your laser in X ($130), Y ($131), and Z ($132). You don’t have a Z so that can be ignored. So your workspace size should be 410x400 mm. However, in Device Settings you have the workspace size set to 410x420 mm. So you have a 20 mm difference which could lead to crashes. Change the size in Device Settings and retest.
