I have an ox cnc that I added a 2.5w diode laser to for engraving. I use a uc300eth to a gecko540, I also 3 other breakout boards for additional inputs and outputs. Using the post processes from jtech to use the M3 command works great. The only problem is the delay and I get excess burning. I also got the postprocessor for m10 and m 11 which has no delay. I have the laser on pin17 and port 2. Running a vcarve file with this post processed gives me no laser output. I am also trying to use the TTL on the laser driver board, but can’t figure out how to hold this up to the uc300eth and pin outs in uccnc.
Any help would be greatly appreciated.
