X2 CNC Conversion
#16
I've often thought that I should have bought steppers with double-ended shafts, so I could crank the table by hand.

As to whether it would harm the steppers, I recently built a stepper drive for a telescope equatorial drive. Since it is connected to the worm by a 1:1 belt system, it was easy to add a small crank. When I disable the motor, it is easy to crank the RA quickly to wherever I need it.

The interesting thing is that, when the power to the control system is off and I crank the RA, the LED on the control unit lights up. The stepper makes a good generator.

If you can't get one, make one.
