Ebay Chinese Routers (CNC3040) - anyone purchased one of these machines recently?

The reversed direction was a joke right? I think it confused a few.

Anyway it does sound like wire, as said just move it to a malfunctioning position and test the continuity with a multi-meter. At the motor end you probably don't have access to the bare wire so you could push a pin through the wire insulation into the core and then you can test from that.

To be honest though, wire doesn't tend to break, the connection points do, at the plug and at the motor. You might end up needing to open the motor case to check where the wire joins.

No joke sadly, thats what it does. Starts out on z+ for instance then reverses to z- or other way round.

If i jog the gantry around i can feel that there is little power on the zaxis motor because i can move it manually until it gets to a position on the bed where power has obviously been restored, then it feels similar to the x y motors. Guessing that its a cable/connector problem of some sort. On closer inspection the cables do not look new and are probably reused.
