Want to manually control a stepper motor on a single axis. In this case the Z-axis. Similar to the controls on my friend's CNC machines.
Rotary encoder/Hall Effect on a large dial for manual input of up/down. Dial turned CW direction would be up, CCW would be down. Faster the dial is turned the faster the motor turns.
Three position switch for selecting tenths, hundredths, or thousandths. No readout needed as I have a DRO for the machine already. Maybe this station could be the input/output for a stepper motor driver? Then I'd just need the power supply and a motor.
Once an initial design is done, I'd layout the circuit on a proto board and do the testing. Once the testing is done and everything works. I'd need a final schematic, a pcb file that I could send out to a small quantity board house, and a parts list (BOM). Preferably through hole on the circuit board/components as my eyes and fine motor control are no longer good enough to solder surface mount components.
I don't have the hardware skills anymore to do this so I though I'd inquire here. Not expecting it to be free.
I'll ask some of the hardware guys at work next week to see if anyone is interested, but I thought I'd ask here first.
