Circuit experts stop in please.

I’d like to do this but just dont see having the time, and I’d have to refresh my mind on the coding necessary as it’s been a while.

But let me understand what you are trying to do here…
-Three output channels controlling three motors?
-What kind of environment is this in?
-What kind of precision is required?
-I’d use stepper motors over encoder wheels, all that you’ll need than will be limit/home switches.
-You are probably looking at having 6-7 input channels for position feedback and some type of push-button control switch.

-Yes three outputs controlling three separate motors. Channel one doesn’t even necessarily have to be a stepper circuit. Could just be a reversible DC current driver for a 12-18v motor, limited by aforementioned limit/home switches and activated by a momentary switch. channels 2+3 however would have to be stepper.
-The controller would be subject to ambient temp+dry, but if possibly to pot the circuit and use an external finned thermal sink to make it water resistant… again another benefit.
-Precision…If you mean precision by increments of movement, then i’d say 1/16th" is more than acceptable for the application. This doesn’t require .001" accuracy.
-Stepper motors would be ideal, as I can get fully sealed units that would be possibly subject to some moisture.
-This is your realm, if you say 6-7 inputs then 6-7 inputs it is

This is not something I’m in a rush for. I’m looking to find someone who may be able to build it over the next 3-6 months now, rather than waiting until I do require the piece.
