I noticed that the heatbed cable would snag on the enclosure when the y-axis was moving towards me (positive direction?). This is a simple shroud that attaches via double-sided tape (or just sits there) and prevents snagging. Initially it looked like a loose cable was causing large layer shifting so I wanted to broadcast my solution to the elusive problem.
*note the mini should not do this normally. Proper wrapping of the cable/ cable management should keep it up but I like belt and suspenders
