Hi All,
I have a four axis desktop router I've been running for a number of years Using Windows 7, Mach3, ESS, Generic BOB and H bridge stepper drivers. All been working fine and now I'm adding a Sculpfun S9 Laser module.
Attempting to setup variable laser control using the spindle PWM output from pin 17 port 2 of the ESS.
I'm getting no PWM just full power on or off using M3 Sxx to set power and M5 to turn off.
The output from port 2 pin 17 of the ESS goes to OV or 5V and no PWM measured from pin 17.
Watched a lot of YouTube for help and a number of forums which all basically say it should work.
One difference I have set 35000Hz in the base kernal and not 25000Hz, not sure if this will cause any issues with PWM.
Any ideas welcomed.
Cheers
Nico.
