Hello everyone,

I just got a Chinese 6040 USB Mach3 CNC machine.

The board is a BSMCE04U-PP and the VFD is a PRT-E1500W.

The problem is that I can't control the spindle with Mach3. It works in manual mode!

I have tested several spindle configurations in the Mach3 configuration.

Does anyone have any ideas about the problem?
