Hi has anybody noticed the following problem:
I wanted a lasercut square using 3 mm plywood and Luban.
Settings 500mm/min and 100% power and 7 passes.
Printing starts fine with the fan going strong.
After one round of cutting the fan shuts off and the laser carries on cutting merrily and smoke starts coming out of the module.
To check I opened the side panel and can see the fan shutting down.
Tried the same using Lightburn and the results are the same.
Opened the gcode and removed the M107 ( turn fan off ) command which resulted in the fan NOT switching off until the cutting was done.
