Yesterday I tried a print and guess what?


Shift is on the Y axis only

After a few minutes of Googling found this Web Site now comes the testing of all reasons listed for why my print after 2 years has shifted lines.
Well maybe should not say all reasons, some firmware settings may be eliminated after many successful prints.

Oh! Speaking of firmware, thought of (static discharge) maybe causing Flashed firmware corruption re-flashed known working Copy.

I started by replacing the Y-Axis bearings and I think I replaced the Y-Axis Stepper motor, May do this again may have put the same stepper back in!!
Anyway the shifted layer persisted and in the exact positions, it is not G-Code, have same G-Code running perfect on 2nd 3D Printer.
Rotated the Model 90 Degrees and no Shifting anywhere on the model...

This is your thread so I will create my own if cannot discover the reason why. Remember read this Web Site it may help you.
