Motor setup for Laser Bed Elevator .... NEMA 17

Electronics
1

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:

Thank you very much.

You’ll notice that you need to control 4 different windings in sequence to manually control a stepper motor.

Why don’t you use a geared DC motor instead. It can operate with controlling of just one wire pair.

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.

Could you point me in the right direction for a DC geared motor ? Would like to find something with about the same footprint as a NEMA 17.
Thank You.

Not the same as a Nema footprint but will give you some choices & ideas.

Some ideas;

My lifts first controller. Stepper + Light object controller
