Prusaslicer does not have a printer entry for MK4S Input Shaper 0.4 nozzle

So after continually getting gcode not for this printer errors I looked at the gcode and see this line

M862.3 P "MK4" ; printer model check

But there is no such printer in the prusaslicer printer list

My printer is a MK4S with MMU3 turned off and input shaper turned on

Is there a way to setup Prusaslicer so that my printer is selectable?

The mk4s profiles are all with IS, Prusa decided since they were not creating non IS versions there was no need to explicitly say they were IS

Leaving us with the problem that the printer and prusaslicer cannot agree on the printer model

Since the world and his bother are not reporting that specific problem, it indicates a user configuration problem

I suspect so, but I'm not aware of any 'configuration' adjustments I can do on the printer other than what appears on the menus. SO likely I am missing something basic in Prusalslicer since I get the mismatch problem on both my MK4S and My MK3S

The fact it is happening on two printers it is probable that the issue is with slicer. If I were you I would redownload and install the profiles and reselect the printer profiles. Then try a test print with a bog standard, out of the box printer profiles.

Oh and check the printers correctly know what they are, on the printers:

Settings / Hardware / Printer Type

Here's what I see when I slice with the default Mk4S profile:

M17 ; enable steppers
M862.1 P0.4 A0 F0 ; nozzle check
M862.3 P "MK4S" ; printer model check
M862.5 P2 ; g-code level check
M862.6 P"Input shaper" ; FW feature check
M115 U6.2.2+8853

I think it's time for you to update your slicer and profiles and/or reset them to current defaults.
