Make sure the controller is reporting positions in mm, as expected by LightBurn ( $13=0).

Set your machine status reporting to be relative to the workspace origin, not the machine origin ( $10=0).

If your machine uses negative workspace coordinates you'll need to apply a workspace offset ( G10 L2 P1 xx yy).

The pause, which happens on older versions, or when not using Laser Mode, will cause excessive burn spots when engraving images.

If you have an older version of GRBL (prior to 1.1f) it's highly recommended to upgrade the firmware, as Laser Mode also prevents the machine from pausing with every power change.

You might need to enable "Laser Mode" if you have GRBL 1.1f or later ( $32=1).

The value in LightBurn is called "S-Value Max", in the Device Settings.

You might need to adjust your spindle max RPM value ( $30) to match the LightBurn default (1000) or vice versa.

Now lightburn works for me with all "start From" modes without crashes or errors.If you have a GCode-based system, like a Shapeoko, Eleksmaker, X-Carve, or Acro system, you might need to make some simple changes to get the most from LightBurn. I managed to bring G54 to the correct value indicated above. Hence a completely wrong offset for my frame (especially with a z other than 0)

Once this is done, if the problem still persists, starting the cut in lightburn in absolute coordinates mode, an error 2 will appear in the console and the command will be ignored, then, check if any offsets have been stored with the $# command. To activate the software movement limits, $20 must be set to 1 (therefore the command to be given in the console is: $20 =1) The limits are stored in the variables $130 and $131 and in the case of my atomstack x 20 pro both must be set to 400. the check that when a movement to the laser axes is requested, this movement is within the physical limits of the machine ( x +400 y +400) otherwise it crashes. If you give the controller the command $$ you will see a list of settings which are stored in eeprom and in my case were:įirst of all I have activated the software limits, i.e. If you can homing the laser correctly (left side down) but when in a cut you try to start with absolute coordinates and your laser goes right banging, then, like me, you have some wrong settings stored in the GRBL parameters. If you too, as happened to me, have problems in the start from settings of lightburn with your laser atomstack x20 pro, I can give you my indications (completely personal and referring to my setup) to solve the problem in a short time.
