My new shield is ready

Finally my stepper motor drivers arrived and I’m ready to move on. I’ve placed them in their sockets and have adjusted the drivers according to this procedure.

Arduino with GAUPS shield and stepper motor drivers.

Unfortunately I’m not ready to go because my Kress 800 FME spindle is broken. 🙁

I suspect that the carbon brushes are worn out but I’ve returned it to the reseller so we shall see what happens…
