Higher temperature after IS upgrade

Has anyone else noticed that you had to increase the temperature in the nozzle after the Input Shaping upgrade?

I've noticed that my filament is matte rather than shiny which is a telltale sign of to low temperature. Seems to mostly affect location where the printer really speeds up, such as perimeters on long straights and infill.

Thats to be expected.  Higher throughput from the hotend is going to require more temperature to keep the filament flowing.

I expected Prusa to adjust the filament profiles for the higher speeds.

But I realised that one of the culprits for me might be the Nozzle X nozzle that I have that needs higher temperatures.

What do you mean ?  Prusa HAVE bumped the temps for IS.  I just installed the current Mini and Mini IS profiles and for example on the Generic PLA settings for the Mini the temps are 215/210 (first layer/other layers) and on the Generic PLA for the Mini IS the temps are 230/220

They haven't been bumped up on my preferred filament from addnorth that has profiles in PrusaSlicer.

I have previously been in contact both with Prusa and addnorth about the filament profiles. Apparently Prusa runs their own tests on all filament that they create filament profiles for and we as users cannot send in changes to these. Only Prusa and the provider.
So I guess that Prusa has decided that either addnorths filament doesn't need any changes, or that they just haven't created any IS specific filament profile for addnorth.

Fair enough 🙂  Although if you are using nozzle x you should be running your own custom ones anyway (like myself who also has a nozzle x fitted).  Never rely on prusa to do everything for you. 

Use their changes to make informed decisions on your own profiles before you roll them in.  While the profile dependency is a wonderful tool for prusa you can never be certain what changes have been made to the underlying settings.  Its easy to miss stuff.  Far better to keep your own copies and then use the profile compare tool in PS to see what changes they are making.

Oh and don't forget to do regular export Config Bundle backups to save your custom profiles offline to some secure storage.  Just in case.
