X Axis failure

So in an unrelated failure, the wire for the heatblock cartridge broke.  I had to replace it, pull some of the extruder apart and do all that.  Finally after 3 other problems filament is now feeding through.

However after starting the wizard calibration I get an X Axis failure.  I made sure to tuck all the wires in nicely along the fan, the screws mounting the extruder onto the axis aren't too tight and I can push slide the extruder very easily but when I tilt the machine the extruder won't move so I'm positive it's within tolerance.

When the test is running the extruder will gently bump the left side, move all the way to the right and gently bump that side, then move all the way again to the left and bump that again then say that the test has failed.  I'm positive the extruder motors are fine, I didn't need to touch them and they worked pre nozzle failure.  I did have to cut the zip ties and reapply them, is it possible those can be too tight?  These machines are far too finicky and I'm perplexed as to what the problem can be.  I've seen other posts on this topic and they all involve pulling everything apart but that seems overkill considering I've only had to dismantle parts of the extruder.

Check how the zip ties are installed

Compare the way the zip ties meet the extruder body with the pictures in the assembly manual.  If the zip ties are not snugged to the extruder body properly, I have seen the X calibration fail.  Also, if the bearings are creating too much friction along the X axis, the same test can fail from uneven tension readings as read through the X motor.  A common cause for that is the back plate that holds the extruder body to the X carriage has been tightened down too much.  Those screws are barely tight at all when set up correctly.

Thank you, this did seem to solve the problem... for the X axis.  Now it would seem the Pinda isn't registering on the Z axis.  The Pinda is over the build plate, it's maybe 4mm above the nozzle tip.  But when the wizard starts the Z axis alignment; the extruder just moves down until it crashes into the build plate. There's no debris on the sensor as far as I can figure.  I'm about to check and see if the Pinda is still connected to the Einsy.  Otherwise I can't figure out why this problem has arisen.
