I have searched for a diy method of how to manually control a 6volt 2 amp stepper motor. I have a medical problem with my right sholder and want to be able to move the table on my mill/drill using variable resistor for speed and a toggle switch for direction. I have installed 2 steppers that belt drive the table and eventually will upgrade the components for a 3 axis cnc. I have built a cnc foam cutter using the Hobbycnc board but would like to mount the manual control on the machine itself so I don't have to keep going to the computer to move the table. Turning the handles with the steppers connected even with out power is a too much of a problem.
If someone has an idea how to go about controling the stepper or a schematic it would be appreciatted. As a last resort I may have to figure out a way to disengage the drives so I can use it normally.
Thanks, John
