Hi Everyone! LightBurn chiming in here.
It appears that with a recent firmware update, all Snapmaker devices (not the Ray, which already was GRBL) now present as GRBL devices, rather than Marlin. This has the lovely benefit of breaking comms with LightBurn until a new device is created. Any Snapmaker devices currently using the Snapmaker Device Profile or Marlin device profile in LightBurn will no longer work after this firmware update.
LightBurn users need to be especially aware that if you want to avoid black borders when carving images (using non-Greyscale image types), you need to add M4 S0 to Start Gcode due to these changes
We recommend that all users use the LightBurn Grbl profile (and provided .lbdev files from the Support page for your specific Snapmaker Device) and not the built in Snapmaker one.
What’s worse, this means that rotary will not work for anyone who has the latest firmware because LightBurn has Snapmaker specific logic for Rotary. If you use the rotary axis with LightBurn and your Snapmaker, we do NOT advise you update your firmware at this time
Note: Devices even get discovered as Grbl now via Find My Laser, NOT as Marlin or Snapmaker.
From our Snapmaker contacts:
the new firmware has been out for a while now (v2.5.21 was released on 20231013). Also of note, we released an important fix related to lightburn in v2.5.23.(We strongly recommend that users upgrade to this version and it has been released)
