MK4 with MMU3 Profile Dependencies
I recently added the MMU3 to my MK4 printer. I noticed that in the Prusa Slicer program (2.9.0) in the filament section under dependencies it lists the "Compatible Printer Conditions" as follows:
printer_notes=~/.*PG.*/ and printer_notes=~/.*MK4IS.*/ and nozzle_diameter[0]!=0.8 and nozzle_diameter[0]!=0.6 and printer_notes!~/.*HF_NOZZLE.*/
I'm not sure what all this means but given I have a MK4 and not the MK4S it would seem to me that this is incorrect. Can anyone please tell me what all this means and what it should look like for the MK4?

Its IS, which stands for Input Shaper. Not S.
RE: MK4 with MMU3 Profile Dependencies
Thanks for point that out. I'm not really sure what the differences are between the MK4, the MK4S, and the MK4IS. I was also looking at the .8 nozzle diameter and the term HF_NOZZLE which I'm guessing means High Flow Nozzle. My MK4 uses the standard .4 nozzle. Are these settings something that should be changed?
RE: MK4 with MMU3 Profile Dependencies
As long as you select the correct printer combination to install then the profiles available will change to match. The whole point of this is that Prusa have done all this stuff behind the scenes to make sure that only what they want is shown regards compatible profiles. People usually complain about the inverse that stuff they had showing for one printer is NOT showing when they select a different printer.
So if you have added a MMU unit to your MK4 then as long as you run through the install wizard again and have added that combo in the print wizard and then select it to print with, if a filament is available then its ok. Those conditions HIDE the profile when the printer does or does not contain the keywords. As far as filament compatibility theres not a lot of difference between a MK4 and MK4S. There is for IS as machines that are running Input Shaping generally print faster.
Input Shaping is a software technique to damp out movement, the latest MK4 firmwares include that. It isn't related to hardware. So with those conditions if you select a printer with a 0.6 or 0.8 nozzle OR has High flow nozzle defined in the Printer Profiles notes section the filament wouldn't be compatible. "!=" means "does NOT equal"

Thank you for clearing that up. it looks like I did not understand what it was saying and in fact was saying the correct thing. the NOT equal says it all.
