X axis layer shifting
Having problems with layer shifting on the x-axis.
The x-axis seems to shift for a few layers then shift back. Seems to be getting worse.
Tried taking apart the head and adjusting the belt tension. No avail. Tried tightening all of the screws I can reach. Also tried recalibrating.
Only thing that seems to help is to print VERY slowly.
No problem on the y-axis. Got some prusamint petg and printed the belt calibration tool. Looks ok. Pictures attached.
Driving me crazy. Any suggestions would be appreciated.

RE: X axis layer shifting
Check your connection to the Rambo board, it may be a bit loose. I had an Ender 3 with a bad cable between the board and the X axis servo, once I replaced it the problem was solved. Prusa uses higher quality parts, but the plug may be a little loose.

Thanks Bob. Worth a try. I tried removing and reseating the connector for the x axis motor. No joy.
Super strange.

How about a losen pulley screw? Or temperature-profile issue?
Is it happening allways?

Hi Zoltan,
Yeah. It does seem to happen consistently. Often in the same place if I print the same file.
What I cant figure out is why it shifts back. If it was missing steps, I would think it would just get further and further off.
Also happens in stealth mode, so it cant be crashing and re homing.
I will check for a loose pulleys.

Solved!
Tightened the screws that hold the x axis stepper motor shaft to the belt.
Also reduced the max acceleration in the slicer, but I think the tightening the screws did the trick. Printing a old file to confirm.
Thank you for all of the suggestions here.
