Hello,
I recently added a 6W Opt laser to my Avid PRO CNC router. The router was converted to a UCCNC 300UCETH controller from the as-built Mach3/Smoothstepper. The laser seems to function properly, but I am experiencing a heavy burn spot at the start and stop of segments while engraving. I am assuming it is a dwell issue for the spindle spin up. I am arming the laser with M03 and using M10 Qx to control the laser power. I played around with the M03 delay but that didn't seem to make a difference. Any suggestions would be greatly appreciated.
