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

@swrightlast
the image did not upload -
@Veti i couldn't get one of the images to load...still working on it. I'll reload the one that did load.
-
for others this seems to be the datasheet

@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.
-
you could try and post it somehwere else and link it. like

-
from the spec of the motor i read that yellow and red should be one phase and green and grey.
if that is true. your wiring is incorrect.
-
@Veti my z wiring is the same, and it functions fine.
-
what is the resistance between the
red and yellow
green and yellow.
cables -
@Veti I get no reading on either one
-
just to make sure. you measured while the cable is plugged into the motor?
is there any resistance between the yellow cable and any other cable?
can you check directly on the pins of the motor? -
@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? -
@swrightlast said in STEPPER AND HOMING PROBLEMS:
green/yellow: 2.4 ohm
so you had no resistance with the cable. this suggest that the cable is broken.
-
@Veti I have new cables coming....check back on this post next week. Thanks everyone for all your help so far.
