My Klipper-ized Sovol SV06+ is having an issue where it reaches about 4 inches on the Z axis and it goes bad. Some examples are below.

Make sure your Z axis rods are:
My guess is that something is wrong with one of the rods about four inches up.
Another possibility is something is wrong with the alignment and they’re not parallel. They could be wide enough at the base but get too close together going higher up.
