When I try to rotate the rotor the stepper stutters back and forth briefly but doesn't move. I swapped my motors and it seems to follow the rotor connection. I tried swapping the stepper drivers and problem remains on rotor port. I'm assuming I have a bad solder connection some place but initial inspection looks good. Anyone have a suggestion on where to start looking? Thanks!
2020 is almost over and I really need some time off. So please be aware, that there is no shipping between 22.Dec and 04.Jan. (But you could still place your order and save 7% with the coupon code 2020isover :)
Hi Grant, that‘s quite weird. Could you swap the motor cables? (I unfortunately used one batch of cables, where two of the wires have to be swaped on the motor side/wider 6pin connector).
The one motor doesn't have a detachable cable, but it does work fine plugged into the turntable port so I'm guessing the motor and cable are fine.
I reheated my solder connections on the stepper jack and it seems to have fixed it. Thanks for the help!
