Beautiful work Dan. How did you get the JTECH LASER
to work with mach3? "Spindle as laser"? I spent the day yesterday getting mine working using "Spindle PWM" using the M3 command and it works beautifully however I'm getting a two second or so delay turning off and on which is causing burn spots so I'm going to order the converter board because I also want to do photos.
I tried the M11p# (16) command but it does not work, probably because I have an Ethernet smooth stepper. Maybe today I'll set up a "spindle as laser" configuration and try that and keep the current one and rename it laser PWM. So I feel your excitement with the laser! Congratulations.
