Here's my video from almost 10 years ago.? The single button step distance was set to the amount to turn.?? I drilled and tapped a number of mounting plates and holders to match the size 23 stepper motors used on my mill.? The holes all lined up perfectly and the parts were all interchangeable.

Thanks, John - was that on the rotary table, or on your belt drive one?

This is the highest rated Nema 17 I found, 2.3a should work with the little TB6560 driver recommended in the ¡°Arduino rotary table for dummies¡± thread on homemodelenginemachinist.com:

Any insight on the control interface? It looks like yours had pushbuttons arranged kind of joystick-like - is that for setting up as well as operating? I thought maybe just a couple big buttons for left and right, in addition to a keypad and display, would make it a little simpler for me to run.

It would be interesting to rig up something like the RELS on my little antique horizontal universal mill for hobbing but I think the 3¡± swing on my dividing head is too small to worry about powering it for that. Don¡¯t know how many true axes that would be, with the table running at funny angles ; )

I used a Nema 17 for many years, it worked vert well, changed to Nema 23 during the full mill conversion to CNC , thus making it a true 4th axis machine,
