I run milling CNC with mach3, smooth stepper and C25 breakout board

I try to setup PWM output for my spindle on my smooth stepper board....

I was connect scope on my output #14 port 1, and I do not see pulse....
 
I had setup output #14 like X axis motor for testing my output and  I see good and stable pulse on my scoop, but if I setup for spindle, it do not work

I had setup port on motor output page, in spindle line, and check PWM in spindle setup, all setup seem good,
I had try to setup spindle with step/direction and It do not work, I had same problem...

Are you checking the PWM in the smoothstepper config?
Hood

PWM was checked and base frequency is 7 HZ

Have you tried changing the spindle frequency in the SS config page? (not the base frequency)
Hood

no, I will try it

I had try other port speed (128, 256 and 1 ghz) without change  

Might be best to email support at Warp9
Hood

okay!

 when you said about the Base Frequency, were you talking about the one in the SmoothStepper config or in Mach? It needs to be the one in the SS Config.

I had setup 7 hz for both
