RepRap Firmware GRBL compatibility or laser optimized mode ?
February 13, 2021 06:13PM
There is a topic on the LightBurn forum called: LightBurn compatible with RepRap? (DuetWifi), stating:

"Marlin based firmware is pretty bad for laser use. They interpret G0 and G1 moves identically, whereas all other modern firmware treats G0 as a non-cutting rapid move. … "

Emulation type that is optimized for use with lasers or plans to add GRBL mode ?

The standard builds of RepRapFirmware have supported laser mode for years. Use the M452 command (https://duet3d.dozuki.com/Wiki/Gcode#Section_M452_Select_Laser_DeviceMode) in config.g to switch the firmware into laser mode. Have Lightburn generate GCode that uses the S parameter of the G1 command to set the laser power.
