Re: Brdgprt CNC2 w Centroid

I forgot to answer the question about testing. First look at the motor connections to the driver. There will be 8 wires. Disconnect the orange wire and the orange/white wires. This is phase A+ . With a good VOM you should measure .3 ohms across these wires. Reconnect.
Then do the White/black and Black wires, this is A- Reconnect. Then the Red and Red/white wires,. This is phase B, measure and reconnect. Last is the white yellow and yellow wires. B- each set of wires should be about .3 ohms so you will need a sensitve ohm meter.
If any set of wires shows a dead short or a open circuit then that is your bad motor.
