I've been trying to get an RPM gauge working correctly. It does move up and down the scale correctly however it does not reset back to the same position on Hardware reconnect.
I think I am right in saying that simvim should move the needle all the way to the mechanical limiter upon hardware reconnect however my X27 stepper just make a noise without movement.
+5v Input to the Easydriver. MS1 is pulled low (Quarter step mode (I think!))
