Does demo Mach 3 do pwm output?
« on: October 17, 2009, 05:28:23 PM »
I am unable to see the pwm out of the demo Mach 3. I am about to purchase Mach 3 but I would like to know that it will output pwm for heat control of a hot wire.

Never used PWM myself but I am 99.99% sure it is available in the Demo version.

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.
