Filament temperature - MMU3 profiles
Hi.
Just finished installing my MMU3 on my MK4S and I am printing test objects.
The MMU3 itself seems to be working perfectly!
However I notice that the texture of the printed objects is rough and weird. Then I see that the printer is printing at 225 degrees C. (PLA)
I go to prusaslicer and check the temperature settings in the filament menu, and notice that first layer is set at 230C and other layers at 225C. This is a prusament profile. I check all other installed PLA profiles and they are all the same. If I go back to selecting the regular MK4S profile (non-MMU3) and check the same filament profiles, they are back at regular 215C.
Is this normal? Is there a reason the profiles for the MMU3 are set a a much higher temperature than the same filament profiles for non-mmu3 printer?

Interested to see if you have any further updates with this?
Did you try decreasing temperatures back to their pre-MMU3 levels to see if it made any difference?
RE: Filament temperature - MMU3 profiles
I cannot confirm. At my printer the temperature did not change. Could it be that you have additional drag / resistance on the filament delivery path? I had similar experience with TPU where it was not possible for the nextruder to supply with enough volume.
