I’ve done some custom calibrations on mine so if your finished products aren’t the size you expect them to be another adjustment can be made.
The $30 = 255 is one thing i’m suspicious of.
130, 131 & 132 are should be 290, 170 & 40 respectively.
Open LightBurn with your engraver connected.
along the top bar (left side) click ‘Edit’
wheel way down the list to ‘Machine Settings’ and click it.
A window should pop up and Show you $30 (Max spindle Speed)
I imagine it says S=1000. If it does, open the console window and type:
$30=1000
That should push that number into your laser controller for $30. You can check to see if that worked by entering $$ again. Worst case, if you need to change your settings back - you have posted them here for future reference (and you should probably make a text file, and note changes - and dates you change stuff,) so you can refer to them later if need be)
Let me know! thanks!
