I have a NEMA 17 motor to drive a belt, gears, etc to raise/lower an elevator for my K40. I would like to keep the wiring as simple is possible, i.e., no controller board. What I would “like” to do is use a DPDT momentary switch to raise / lower the bed. I would like to directly wire the NEMA 17 to a power supply (optimal voltage ?) .
Since it is all “manual”, is it possible to wire the 17 this way? I do understand how to wire in a limit switches, it’s just the motor/power supply that bugs me. Crude sketches always welcomed!!! I do have this if it has to be used:
To use the stepper you will need some sort of controller, the only way to avoid that is, as @dougl says with a dc motor.
It doesn’t have to be a microprocessor based controller, if you add a second endstop switch it can be done with a transistor circuit and a dpdt up/down toggle
The stepper motor with belt is suitable for long-distance transmission, and the gear structure is compact. Gears are good for large torques, belts are good for small torques.
