Many years back, I bought an old ex-production version of a Universal laser with a Synrad 25-Watt. It was on an assembly line so it is is just a bare specially built frame.
I built a safe enclosure for it and it It has been running fine for the hobby stuff I mess with but, I want to replace the controller and software. I have looked at current software offerings (LaserWeb etc) and for 40-bucks, LB is a steal, so would like to go with it.
I am pretty sure I can run it from an Arduino or similar as the Synrad has it’s own built in controller and and only needs a PWM signal to control it. From the manual,
ontrol (CTRL) Input
Logic Low (Off State) … 0.0 V to +0.5 VDC; 0.0 V nominal
Logic High (On State)… +3.5 V to +10.0 VDC; +5.0 V nominal
Maximum Current Load… 6 mA @ +5.0 VDC
Tickle Pulse Signal
Tickle Frequency 5 … 5 kHz
Pulse Length… 1.0 μs ± 0.2 μs
Pulse Rise/Fall Time… < 100 ns between +0.5 V to +3.5 VDC
PWM Command Input Signal
PWM Frequency 6 … DC to 20 kHz
PWM Duty Cycle … 0% to 100%
I have an MKS SBase board from a 3D printer and have installed grbl-LPC but unsure where to go from there. Where/how do I connect the Synrad PWM to the MKS etc?
Thanks for any help.
