Hello , I have the same question
I already read,
that someone controls his laser with the pwm modulation
of the axis stepper in mach 2d mod.
I have a synrad 48-1
tickle freq 5khz
pulse length 1mikrosec +- 0,2 mikrosec
raise fall time <= 100ns 0,5v to 3,5V dc nominal is 5vDC
Can anybody explain how to control wtih mach3 or linkmotion software
I prefer mach3 because I already have it!
Thanks and best regards bjoern
