Hi everyone,
I decided to motorise the lifting of my SIEG SX3L milling machine tired of turning hundreds of times to obtain small vertical movements: I used a stepper motor with relative driver and a 250 (W) power supply,
the most difficult part was understanding how to reverse the direction of rotation, I succeeded using the relays, making the driver feel a "logical" change with the opening of the normally closed contact, the driver reverses the direction of rotation; It seems trivial, but with a stepper motor it's not really like that.
Hope you enjoy the video,
Alberto
