Y axis issues

I've tightened, loosened, and rebuilt the y axis repeatedly. I've gotten all the other axis to configure and setup consistently and correctly.  However, i've gotten y axis to consistently configure, but it won't setup properly, being about 1/2 way off the mark.

RE: Y axis issues

A bit more clarification.

I purchased a MK3S kit.
Current Firmware version: 3.8.1-2869, have not updated.

After several rounds of troubleshooting, I've gotten the self-test to perform consistently. The X & Z axis line up properly. The Y Axis, however, appears to be about 1/2 cm off the mark, per the photo I've linked. As a result of this, the follow-up XYZ calibration fails, being unable to find the mark.

Things I've tried
Tightening the Y-Belt
Loosening the Y- Belt
Flipped the Frame holding the platform
Re-seated the drive wheel on the Y-motor.

Worked through several other troubleshooting threads.

RE: Y axis issues

Hi David, 

Does your Y axis move back and forward smoothly, by hand? 

if not you may have over tightened your Y axis Ubolts

Did you lube the linear bearings when you built the printer? 
YES I know what the assembly guide says... 
If not, now might be a good time...

Is your Y axis Belt adjuster the correct way round?

Could you be having issues due to friction? 

Is your Y motor toothed pulley touching the motor or mounting bracket

regards Joan
