Shortly after I posted about my weird first layer issue the z axis motor failed completely. It is an oddball cheap motor and I could not find a direct replacement. The screw was also a very small diameter piece of all thread. I replaced the motor with a standard nema motor with a printed bracket. I did have to do some surgery with a Dremel and drill in order to get the new nut mounted to the carrier. I also had to change the steps per mm in firmware for the new screw. I haven’t changed any of the slicer settings just different filament which is stringing pretty badly and I think the printer is going a bit fast. Other than that it’s running pretty good.
