<p>Can anyone tell me what would cause an entire print to be shifted about 8mm?
I have a new Elegoo Neptune 3 Pro (which is doing an awesome job so far!).
I started printing this <a href="https://www.thingiverse.com/thing:5414034" rel="nofollow noreferrer">Treasure Chest Puzzle Box</a> overnight, and this morning it looked pretty good until I noticed that after approximately 3 layers, the print shifted by about 8mm. I think it shifted again by about 1mm after 1 layer. The rest of the print is perfect.
Unfortunately, I pulled the print off and closed my Cura file before I took note of which direction the print was on the bed, so I don't know which dimension was shifted - the direction the bed slides or the direction the extruder head moves.
I printed on the normal Cura profile.
Thanks.

One of the following might be the case:

* Your X or Y belt may be loose. Are the belts under enough tension?
* The speed / acceleration / deceleration of your head may be so high that the belt slips. Can you try to move the bed or the head and see if the belt slips?
* The head of the extruder might have got caught in an extruded part that somehow got lifted up or fell over. Can you see any sign of a part that got bumped by the extruder head?
* Your cat might have gotten a little too interested and whacked the printer's bed with its paw.
