Your curves/circles are pretty decent (from this angle).

I would not use a fan yet, because if you had the problem with overheating drivers this would happen constantly, not just once during a print.

Your problem is over-extrusion. Eventually, there is enough build-up that your nozzle can no longer plow through the excess layers and gets stuck. The bang is the stepper skipping when it cannot physically move to where it is commanded.

Calibrate your extrusion.

It seems odd that the x belt would be loose enough to do that and yet print as good as your picture....it does however look like you are overextruding a lot which can cause lost steps as seen in the pic.

If the belts are tight, then you may need to put a fan on the Printrboard. Over heating stepper drivers can cause shifts.

I have a RAMPS/Mega board and adding a fan solved my Y-shift problem.

Looks to me like your right tighten the belt up a bit. It also looks like you are over extruding a bit and I am guessing your hot end is dragging on the print some.

Hello.

Anyone knowing why this is happening? Do I have to tight the belts?
It's the Y-axis that is slipping btw! I hear a "klunk/bang" sound, and then it print a little futher. as it slips on the belt?

Can anyone help me get this fixed?
