I am looking for suggestions primarily for motor controllers.
I need to control 8 levers, programatically setting them in a sequence of different combinations of up and down. Max torque is 200 oz-in, holding torque is 100 oz-in. Motor should spin at around 10 revolutions per second. I was thinking of using 8 stepper motors like 23HS8430 Nema23 Stepper Motor. I need to load a sequence of 1000 instructions where each instruction will simultaneously move each lever to its position for that instruction (up = 0 or down = 1500 degrees of rotation), and then manually trigger the next instructions via a forward switch/button or trigger the previous instruction via a back switch/button. Thus two inputs or one input with two states.
The CNC or D printer motor controller boards I have looked at (e.g. Octopus V1.1 with F446 chip) seem like they do more than I need, and most seem to use Mach 3 software which does more than I need. If I could control this all from a Raspberry Pi or something similar, or if it were self contained, that would be better than controlling it from a computer.
Any suggestions on a suitable motor controller (or suggestions on any other aspects of this project) would be greatly appreciated.
