Greetings all; It turn out that a pwmgen module to control the on time of this pump motor is not sufficient to adequately control the pump as I cannot control the rep rate, even at its minimum rate, once the pump is moving on a per step basis, the minimum rep rate is too fast and it will dump an 8oz bottle of mist fluid in half an hour or less. What I need is a multivibrator whose on and off time I can control independently in order to be able to pause longer between on pulses. It doesn't appear that I can control both on and off times of a pwmgen from a couple of spinboxes in the postgui.xml file.
It looks like timedelay might be the answer but will need a nand2 for a not in the feedback with the 2nd nand input being an on-off control to complete a on-off controllable oscillator. Or is there another module yet that can do all that in one module? Hopefully with less elapsed time in the servo thread, or possibly doing in this 6040, a separate low speed thread for such low speed operations, something that is working really well for the rpi4, the manual stuff like jog dials on the apron running in a 20ms rate thread. This I think needs the finer time granularity of the servo-thread though. Thanks for any helpfull advice, everybody.
