Consistent layer shifts using FW 6.2.2
I have been having consistent layer shifts running FW 6.2.2 on my 2 tool XL. Belt tensions have been set and re-tested as well as varied slightly. All the stepper pulley set screws are tight. On the same part, and the exact same layer, you can hear the x/y steppers stutter and cause an offset. The prints are single wall LW-PLA. Printing speeds are 40mm/s and travel speeds are the default 400mm/sec. Acceleration controls are factory settings. Smaller parts print perfectly, reguardless of their height.

Update:
Going back to 6.1.3 did not resolve the issue.
Reducing the travel max acceleration value did not resolve the issue.
There is no collison, and the issue seems to happen during layer change.
This is almost acting like the issues I had at one point with another brand printer when writing to the USB for power recovery. Any help would be greatly appreciated here. I bought this printer just for this project and this is getting very frustrating.
RE: Consistent layer shifts using FW 6.2.2
There's still a bug in the firmware causing layer shifts with gyroid infill, so if you use gyroid, it might be worth checking if switching to a different infill pattern helps.

Interesting, I do happen to be using gyroid as that is what the airframe design needs. That being said I did try a few more trouble shooting ideas and got some positive progress.
1-Changed out the USB to a Sandisk with no change
2-Tried cloud based download vs prusa link vs direct download, no change
3-Disabled everything I could to reduce memory useage, no change
4-marked the pulleys/belt to determine if it was a stepper missing a step, or belt slippage. Verified that slippage was not happeneing.
5-Slowed the travel speed down to 200, and the travel acceleration to 3000, This seems to eliminate the layer shift, but I am curious if I am just masking a motion control bug?
Thank you!!
