Ray,
Would you care to share how you use the pwm to control hot wire heat? I have a controller board without documentation. I have managed to get everything working but the pwm output.
Thanks,
I use it for controlling a spindle, not a hotwire, but the configuration is pretty simple - Go to Config->Ports&Pins->SpindleSetup. Check UseSpindleMotorOutput and PWMControl, then set the PWM frequency. Set the min and max speeds for Pulley1 in Config->SpindlePulleys. In your case, you probably just want to set 0 to 100, so you can control the wire in %. Then do an "M3 S*********" where ********* is any number between the Min and Max spindle speeds you setup for the pulley, making sure Pulley1 is selected on the Settings age, and it should work.
Regards,
Ray L.
