I have a Lead1010 with X32 control, I can get everything to do exactly as I want it openbuilds control, all axis move, machine homes fine, laser fires at any power level and seems spot on. I switched over to lightburn, finally got it working after turning on [enable dtr signal] and got machine to home fine, control axis, fire low power with fire button, however I went to run a engraving image and it gets about 5% into it and the machine locks up, makes a horrible sound and appears as if there is a mechanical jam, usually the software triggers an alarm 3 with error code 9. I have tried multiple times with different settings and it’s always right at the same point on the image. Now I have unplugged the PWM connector on the X32 and it’s still doing it. Have tried new USB cables, changed my $30 value from 100-15000, changed $33 from 100 to 5000 in many incriments, checked connections all around, no luck. Here are my specs and a sample of the crash. Running lightburn 1.7.08 and version 1.1f.20230129 of openbuilds. PLEASE HELP, LOSING MONEY AND SANITY FAST! Thanks!

For a test change your scan angle to 180 and run it. See if the failure is still at 5% or 95% or other.
What makes you think the pwm has anything to do with it?
Do you have software limits enabled?
$30 refers to the maximum spindle speed. This control is used by all the software package to advise the controller how the spindle speed is scaled. Since spindle speed also controls the laser power, $30, must match S-Value Max in Ligthburn and $31 minimum spindle speed to zero.
Many 8 bit machines only have the spindle speed set to 255.
I assume you figured out the $32 for laser mode.
I’d do what @thelmuth advised … grbl machines aren’t what I do most of the time.
Ok I set the scan angle to 180 and it seems to run fine with that setting changed. Removing the PWM connector was simply because I was not sure if I had the laser wire right, wanted to eliminate variables. It’s a 4 wire OmTech B10 Diode laser that I peeled off my other machine and had no access to wiring schematics, and all 4 wires were black. The laser seems to be operating fine, it functions well with a 180 degree scan angle shift, but running normal still locks up with an jarring noise. $30 and s-value match, $31 set to 0.
