Hey guys,
I just got my old 3040 out of storage after a few years. Prior to that, it ran off a computer with Mach3 and a parallel port perfectly fine. Since getting it out of storage I've been trying to run it off UGS and GRBL with a db25 Arduino shield.
So far no luck. Every command returns an "ok" status and it all appears to be working. However the CNC itself isn't moving, in fact the stepper motors seem to be locked and heating up and the spindle isn't getting any power to it.
I checked and double checked the pinouts, even disconnected the Arduino from the stepper control board to confirm that it wasn't the Arduino causing it. The CNC was working well prior to going into storage.
Can anyone give some advice on how to troubleshoot this?
Thanks!
