So I have a mini mill with Gecko 201's and 250 Oz-in NEMA 23 motors on the X and Y.
The X axis seems weak. I can turn the 1" diameter coupling with my fingers easily. I seem to be dropping steps.
The Y axis is running rough and noisy, but resists turning by hand.
If I switch the cables (the connections are on the driver box, not the motors), the the behavior follows the drivers.
My suspicion is that I have some coolant in the motors or cables which have caused problems with the drives.
I assume I can look at this by taking a continuity tester to the windings and if I find find conduction where there shouldn't be, I have a problem? It looks like I would want to make sure there is no conductivity between AB and CD pins.
Also, after I unplug it, what about the capacitor?
Is there a troubleshooting guide?
Thanks!
