I'm working on getting my printer up and running and I'm having some issues with the Z axis.
I have two issues happening: First is that the stepper motors aren't working when connected together. They work fine individually, but once they are both connected they just hum (very very quietly). I've tried the driver turn pots up to about 10 degrees, but it doesn't make a difference. I'm checking the readings with my meter today, but I'm assuming it may be a bad driver / turn pot.
Also on the Z axis. I'm having issues with the stepper motor / rod connection and the frame rod connection being at a different width than the carriage connection by almost 1/16 of an inch on both sides. The rods are plum, but the pinch points are causing a bow. I'm assuming this is just a PLA or mounting deviation, however, it is causing a pinch point on the bearing at the carriage creating friction and causing resistance in Z axis movement.
