I printed an object that was just short of the maximum print height - as determined by the ability to load on the software without an error. The print finished fine, but the head will not descend. It grinds (groaning sound) but does not move down at all. It still moves along the X axis okay. If I try to home it, the head moves to the leftmost X axis, but groans instead of going down the Z.
There we not issues, that I was aware of, before this print.
