Bad Top Layer
I am getting these cuts in the top layer on 2 printers. Both are MK3S+ with MMU2S. I received my 5 extruder XL last week. I suspect there is something changing in the profiles when I change from the MK3S+ configuration to the XL configuration in the slicer. This issue does not show up on files sliced prior to receiving the XL.
Basic slicing information:
PLA
215 first layer, 205 after
0.2 first layer, .25 after
3 bottom layers, 5 top layers
No ironing
Infill (grid): 5% with 10% starting 2 mm below a solid surface
I don’t see how this is the issue but I typically print with grid infill and the XL defaults to cubic. These parts were printed with cubic because that transferred. I didn’t see it as a big deal, but am testing it now.
These same files sliced for the XL print great.
RE: Bad Top Layer
Just an update: I changed the infill to grid and the problem has gone away. I have run several pieces of the same model with no issues. I am still not sure if this is something to do with switch back and for between the MK3S+ and the XL configuration, but I am now running different instances of the slicer. I will try to run one with cubic infill again to see if the problem comes back.
