General Mach Discussion / Re: Intermittent Stepper Stalling

Hi Hood,
Thanks for the reply.
I have traced the problem back to my breakout board, I swapped it out with a different one and all is well.
I noticed that the stalling only occurred after I switched on the router, so it must have been some noise from the router. The higher I set the rpm of the router the sooner it happened.
All my cables are screened, motors and limit switches so not sure how and where the noise got to my breakout board.
I also measured some strange voltage spikes 15 to 25 volts from the ground of my breakout board to the machine ground.
The problem with the M3 command was the delay settings, my M3 macro is Do SpinCW(), but when the machine is jogging it first wants to stop for the delay time set in the Ports and Pins settings. If I set the delays to 0 seconds it all runs well.
