X-Axis Layer Shifts, My solution  

X-Axis Layer Shifts, My solution

Don't need any help, just writing this so future people can find it.

• I had X axis layer shifts randomly throughout my print when printing PETG.
  • Higher bedtemp than PLA and in a vented enclosure, max temp 35C 95F so not too hot.
• Tightened the belts, lubricated everything, no solutions.
• Noticed that I was actually having the Y axis detect crashes multiple times per print.
  • X axis would rehome after crashes, but due to zip tie placement would rehome at slightly different places, giving me X-Axis layer shifts.
• Y axis is lubed up, belts are tight, no mechanical problems.
• Turned off crash detection on the Y Axis and prints turned out great, no X-Axis layer shifting.

My theory: Something is wrong with the Y Axis crash detection that triggers when the bed gets too hot. (maybe the bearings bind a bit, or the control board gets hot from ambient... not sure) By just turning it off, I avoided the crash detection and re-homing which was giving me X-axis layer shifts.
