Layer Shifting on MK4S
Good Morning -
I am trying to print multiple copies of a bracket using Overture Rock White PETG. When I print a single bracket alone it prints perfectly.
Bracket printed alone and it worked perfectly
But when I try to print 2 or 3 instances at the same time, regardless of their orientation on the plate, I get layer shift at the same place: 48mm (so approx layer 240?).
Same bracket, printed with others on same build plate, with layer shift at same height.
I've tried several times, using up most of a roll of filament, with the same results. I'm open to any suggestions. I need a total of 16 brackets, and they take about 4 hours each, so bring able to print more than one at a time would be better.
I am using FreeCad 1.1 and Prusa Slicer 2.9.4 on a Mac Mini M1 2020 running Tahoe 26.3.1. I have an Prusa MK4S in an enclosure, running Firmware 6.5.3+12780.
Thanks,
Mary.
