Hi Charles, I am using a slightly modified version taken from config/ARM/BeagleBone/CRAMPS
Here is a link: https://pastebin.com/spiURz5j Here is a video from my scope: https://www.youtube.com/watch?v=4nKZhipoK_c Note that I have the spindle speed value wired directly to the PWM value for debug so using MDI I can enter any duty cycle, for example M3 S0.5 After switching to th Adafruit_BBIO.PWM library + Python, I am able to generate perfect PWM on the same physical pin without any problems. Please let me know if you need more info... -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
