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.

Cheers, Gene Heskett
