Introduction, the new guy

As I am new to 3D printing I have had a tremendous career in machining, I see this as trouble for that industry.  Engineering is my new role no longer machining but I did love doing that spent 34 years doing it.

I just purchased a XYZ printer, and have built quite a few things but not impressed with the results.  Having understanding of leveling I just super-glued a dial indicator to the fan on the print head and dialed in the plate using shims from paper in the corners. I was able to get it within .002 plus or minus as this was the bow in the glass.  When I was done I just rotated it and it came off, and cleanly.

After getting the darn thing level I set the z home position using a shim .003 seemed to work pretty well. Printed perfect but the quality is less than expected.  I did notice that as the X axis traveled toward the left it shortened the distance to the material feeder and this increased the force applied by the material feed tube as it was now sharply going up and coming down, the arc was very narrow.  This pushed on the print head and as it transverses to the left it raises the head.  Why I ask and after reviewing this it seems the left bearing is well loose as a goose, no bearing at all.  I asked the question was this intentional or a error.

As you may guess I have since disassembled this contraption correcting the bushing issue and it was done leaving about .003 total diameter clearance for a good running fit and slides like silk.  Ok everything was going fantastic but as we are human and as I had aligned everything back to the marks I had made, I neglected to install the sensor post that engages the sensor telling the motor honey I'm home.  Now I get that 0052 error, and with some work I can change it to error 0032.  This issue is only with the X axis and I have looked the internet over to locate anything on how to correct it.

Long winded but precise in what the problem is does anyone know how to correct this error.  I haven't given up yet.
