Thanks. I got similar answers on another forum. I will wire hotend separately.

I have a 24v, 40w hotend. Can I safely connect to rg45 and cat6 cable? Amps of hotend is 1.6a.

@Veti I have new cables coming....check back on this post next week. Thanks everyone for all your help so far.

@Veti
green/yellow: 2.4 ohm
red/gray: 2.4 ohm
measured directly on motor pins
rechecked at board ends.....no ohmage (sic).....bad crimps or break in wire someplace?

@Veti I get no reading on either one

@Veti my z wiring is the same, and it functions fine.

@Veti yep, that's my stepper. i still cannot get the image of my board wiring to upload. both were jpg, taken at the same time. anyway, my stepper wiring at the board, from left to right is red, gray, yellow, green.

@Veti i couldn't get one of the images to load...still working on it. I'll reload the one that did load.

@Veti standard folgertech nema 17, 1.8 degree. 5kg/cm, 1.5a20191106_095244.jpg

@Phaedrux funny thing is, i only put new board connectors on x,y. z axis homes just fine....z was not involved in what i was doing. the board connector wiring is the same on x,y as it is on z. this just gets curiouser and curiouser. I'm going to call it quits for tonight. Try again tomorrow.

@swrightlast it keeps showing the motor phase error for both x,y.

@Phaedrux I tried it.....no change.

@swrightlast , I must be getting tired. How do I upload my config.g to this discussion?

@swrightlast said in STEPPER AND HOMING PROBLEMS:

Error: M569: Driver 0 does not support mode 'stealthChop'
Error: M569: Driver 1 does not support mode 'stealthChop'
Error: M569: Driver 2 does not support mode 'stealthChop'

Does this give any clue to the problem?

@swrightlast I could not get any resistance readings at all! Probably didn't do it right.

@Phaedrux , standard folgertech nema 17, 1.8 degree. 5kg/cm, 1.5a. checking phase now......stay tuned.

Again, just a short grunt of ratcheting noise, Motor shaft appears to be alternating rapidly between forward and backward movement.

Also got motor phase error thing.
