Benchy - Increasingly bad X-axis layer shift

Hello.

I am dead fresh to 3D printing and am using a MK4 which came pre-assembled.

As you can see, I'm having what appears to be x axis layer shift (Benchy's bow faces to the right on the print plate) in the Prusa Benchy you can download from the Printables website. I've tried two presets in Prusa Slicer, FAST, and STRUCTURAL; structural was by far the worst even though it took longer to print (I was hoping as it took longer the print head would be slower and help me diagnose things).

All calibrations pass on the machine and, after the printer just ignoring the file 8 times in a row, I managed to get 6.1.3 firmware installed.

Can a kind soul help me troubleshoot?

Gonna try upload the images again (there are 3 methods of uploading media in this forum but none seem to work?)

^ Left = FAST. ^ Right = STRUCTURAL

Belts, it was belts. Tightened the belts and problem solved.

My Google fu must have been mad wack until yesterday when suddenly I found all the resources I needed to fix this both on the Prusa website on YouTube.

I must say, though, that the structural benchy on the right is one of the cooler benchys I have seen in a while...  🙂
