RE: [CAD_CAM_EDM_DRO] Re: Brdgprt CNC2 w Centroid

Yes, it has been a year.the machine came home and we put it in cold storage.
At any rate, I now have it in our shop with electricity, light and heat.
More questions.

1 - Motors have 10 pin AMP (I think) connector) but behind that wire case
another set of 4 wires (plus shield) goes into another case - they are
heavier wires like 14-16 gauge and are Red, White, Black, Green and bare
shield. What part do these wires play? I've got to remove this case before
I can get to the wires attached to the 10 pin connector.

2 - In one of the other posts it was recommended to swap X and Y cables to
see if the axis on the controller had been taken out. But other systems
caution against applying power to different drives with motors disconnected.
Is this Centroid system different from Gecko or other stepper drivers that
allows it to be disconnected from motors when powered up?

3 - If motor is bad, where can I source another?

Thanks,

Chuck Merja

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.
