Fail on "Improving Bed Calibration point 1 of 4"
New i3 MK3 kit assembled on 4/6. After running through the wizard with success, the process continually fails after the first round of searching bed calibration points 1 though 4. The first round of bed calibration all check out fine, but when the "improving" sequence begins the bed does not return all the way to point 1 of 4 on the Y near the origin, rather it stops somewhere along the way (noise for x axis belt on motor side seems associated with problem) and drives the print nozzle into the bed and fails. My understanding is that the extruder should be returning all the back to point 1 of 4 next to the origin for the "improving bed calibration point 1 of 4."
Latest firmware (3.1.3) has been flashed. Probe seems to be at good height after ample tinkering.
Thanks for any thoughts

If the belt is poorly stretched, it may "cog over" and cause noise.
Check also if the Y-axis end pulley can rotate freely. If you have tightened the screw too hard, the pulley rotates very heavily.
