What does F? mean on Display
The line on Display between Bed Temp and filename. right after #% and before Time Remaining there is "F"
I've never seen it before! Does anybody know what it means?
Sliced with PrusaSlicer 2.0.0, Printing on MK3S with Firmware v3.7.1. This is only second print with this slicer/FW combination. I don't think the F? was there before but not absolutely sure. It seems to be printing OK.
Curious!
Peace "n" Thanks

Check if the printer is thinking it has an MMU. The F? indenticates which filament is loaded. The question mark because it has no information about it.
Go to support in the menu and scroll down until the MMU entries appers.
I've the same isse from time to time, and another guy in the FB group too. My suggestion, it is caused from noise on the port where normally the MMU is connected, or an PWM, an fan. Maybe an bad powersupply or bad contact.
Resetting the printer will solve this issue, until it appears again.

RE: What does F? mean on Display
sounds like your display may have gone bad; Mine started showing garbage characters intermittently recently too.
Here's what it should look like when all is well (minus the orange, of course, that's not stock)
RE: What does F? mean on Display
The F? appears for MMU2 prints. It indicates F1 F2 etc for filament one, two etc. If you have a std Mk3S without MMU2S then check your printer selection on the right hand side in your slicer. Sounds like you have selected to slice for an MMU2 equipped printer.

Just a glitch, I guess, it's not there on today's print.
I didn't even think about MMU, I looked in Support but that didn't register. Filament wasn't one of the F words that came to mind.🙂
@olef, MMU isn't an option in my slicer.
@knickohr I'll check my cable connections, just to be sure.
Thank you all for the replies. I wasn't overly concerned since it was printing OK, but curious what it meant.
