    Thanks all for your answers, that confirms that I’m not missing something.

    Thanks Zootalaws for the response, that is very helpful.

    cmcgrath5035: The only reason I’m considering using the PWM to drive the step input of a stepper driver is that I have one axis on our instrument that I want to control at a precise speed, and the A, B or C axes don’t really allow that. I already have motors connected to X, Y and Z. I could switch to a DC motor and use PWM to control it, but the speed would not be as accurate.

    Thanks for your answers,

    Thanks, we’ll have to do something else to synchronize our system.

    Thanks for confirming that. I’m writing g-code templates to control the scan path of an instrument we are building. We will need to insert the parameters (position, size and scan speed) into the template. We will just have to do a little more work without parameters.
