Core One+ X- Y- and Z- axis calibration pass, Homing calibration fails

Like the title says -- each axis passes it's calibration but the homing calibration fails. When it tries that calibration, the print head moves to the front right corner and moves back and forth, and side to side a few centimeters. There are no obstructions, I can move the print head freely and smoothly both by hand and using the options on the panel.

This was built from the kit, not preassembled.

Any ideas?

My kit machine had a similar homing problem after passing X Y Z tests.  See my post here.  I got in touch with Prusa and, after many emails asking me to carry out various tests, they sent a replacement heatsink/loadcell and main cable.
