Intermittent Y-shift print issue only with multiple items I have an issue with a Y-shift every few lines only when printing multiple items at once. If I print the exact same models individually, they each print fine. Notice the shift only happens a few times, about every 4 lines, and then stops happening.
I’m printing PLA on an Ender 3 Pro, slicing with Cura 4.8 (Mac).
Any ideas on how to troubleshoot?
I initially tightened the tensioner for the x-axis belt pulley, which seemed to help. Then I double-checked my installation, and realized the belt for the x-axis was on upside down (belt teeth go in, smooth side of belt out).
So I guess it’s actually more surprising it’s been working well until now...
