Very messed up first layers with particular print
I just got my XL yesterday, did a test print that came out great, then designed something to test out printing with all 5 extruders. I've spent all day fiddling with PrusaSlicer and the printer and I just can't get it to print. Here's the first and second layer on my 10th failure:
I can't figure it out. The issue in the last few has been a first and second layer that look like that, then the third layer collides with the second. I did another test print (a disc a few layers thick) using just that particular extruder and PLA and the result was perfect, which is why I'm so confused:
I've pretty much stuck to the default slicer presets (I've tried a couple) and I don't think there's anything particularly unusual about the model:
Any ideas? Thanks

Have you done the Tool Offset Calibration? See Step 18 and following https://help.prusa3d.com/guide/5-first-run_482742#483292

Small update: disabling phase stepping helped a lot with the gaps, but it still seems to try and print into the same layer or lower causing collisions:
Could it be an issue with z calibration across different extruders?

Yep, that solved it. I think something must have knocked out the alignment after the initial calibration, then my second go the nozzles probably weren't properly clean. Heating each head up to 250 for five minutes then cleaning and recalibrating got it working nicely.
