Hi
I'm new to the forum and to CNC. I've just taken delivery of a rather battered CNC3040. Can you tell me if it is normal for the X and Y axis motors to be very stiff to turn by hand. The Z is quite free. I've powered it all up and Z runs fine. The other 2 motors just make a humming noise. I've reconfigured the pins to drive X with known good channel Z but it still won't run. Do I suspect motors, wiring or warped drive chain. I will attempt to get a replacement but am not holding my breath.
Any guidance appreciated.
thanks
John
