Disable Input Shaper for MK4S?
I have just upgraded to the MK4s and just wanted to disable the input shaper, as I had not made the best quality experience with it in the past.
I had learned that I need to go to printers->Add printer, but the only choices available are:
- "Original Prusa MK4S" with no Input Shaper in it's name, but a green Input Shaper badge on the image.
- "Original Prusa MK4 Input Shaper" with green Input Shaper badge on the image.
- "Orginal Prusa MK4" at the bottom in Legacy profiles.
So what is the supposed way to disable the IS on the MK4s?
Use the legacy MK4 profile?
RE: Disable Input Shaper for MK4S?
I am experiencing the same issue's and I believe Input Shaper is the cause, I am wondering how to disable it also
RE:
I asked support the same question today and here was their reply:
Support reply:
ah yes, IS is inbuilt with the MK4S. However IS itself is only a tool which helps mitigate issues caused by fast printer movements, thus allowing the printer to use faster print moves. You can technically slow down the print speeds if there seems to be any print issues cased by that.
My followup question:
Isn't input shaping still active even though you manually slow down speeds? I'm not sure if speed was the only difference with the MK4 profiles I was used to.
Support reply:
technically yes, practically it wouldn't be any different from profiles not having IS active.

So at the moment it seems like IS is always on. for the MK4S default profile. I was hoping to have the option for 2 separate profiles too. One with IS and one without IS.
RE: Disable Input Shaper for MK4S?
There is a M-command for disabling input shaper:
M593 F0
Place it at the end of the Start-G code section of custom G-code tab of the printer
I'm not sure if this code is recognized. You need to perform a test print (calibration cube) with this M command and without.
Would be nice to hear from your result.
