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.
I have that same printer and I’ve got similar issues, although it gets worse as it climbs instead of on the first layer. I wonder if it’s the motor going out.

Ah, Monoprice. I have a couple of their models. I think they’re great for the price. The two I have are larger than this one. However, I really want to upgrade to a Prusa. Auto leveling, a magnetic bed that doesn’t fall apart after a print or two, multiple filaments. Have fun. Print mods. Go crazy with it.
