10W laser module freezes after 2seconds of job

Hello everyone!

im having a weird issues (which i hoped a firmware update solved, but didnt). during some jobs with the laser, the machine starts and freezes after a couple seconds maximum. Laser turns off, machine doesnt prompt any error message, luban stops with “gcode line: undefined” but doesnt prompt any error message. the only way ive found to unfreeze, is to power off and reboot, also restart luban. Ideas?

Very import, this doesnt happen often, most jobs works fine without any issue, even long jobs. the only times it stops, its withing the very first seconds. never stopped afterwards (not yet at least, and hopefully never will)
