Being able to set your own filament can be very helpful or very frustrating.
Let me try to make it helpful for you 
As you can see there isn’t much to see with my custom filaments.
Brand, type and that’s it, no colours, no fancy things.
This way you can keep things neat while also taking full advantage of those PA values we can now store so nicely.
No need to define colour or such in the filament section, this can be set on the fly in the AMS settings later, or in Studio.
A nice option to include all nozzle sizes you have…
But we are now at the point where things quickly get confusing if you don’t stick to the simple approach.
For ever nozzle size you added to the profile or already had as defaults in Studio there is now a dedicated section for all the filament related things.
Means in simple words > You can set all nozzle sizes you have AND set dedicated flow ratios for them in one single place.
Don’t confuse yourself by later adding more filament profiles you won’t need…
Ok, that looks fine now, you calibrated the filament and ???
Right… How to get the calibration to math those custom profiles ???
Take a look:
For each slot I have the filament calibrated.
But I do this the smart way
For the PA profiles you select the filament in question and save the calibration with a name that contains the value.
Makes finding and keeping them tidy much easier.
For example, if you often use different nozzle sizes or hotend you can include this in the file name as well.
So instead of just Siddament PLA matte you add 0.2mm in the name to later know for sure that’s the calibrated value for the 0.2mm nozzle.
You can go as wild as you like here…
When I first tried my luck with these new features I created all the profiles and for all the colours I had around…
The filament quality is good and consistent so the big advantage I had from this multicolour way was that I totally lost track.
Yes, there is such a thing as having too many profiles…
Once you are happy with your results please do export your profiles because Studio sometimes removes your profiles during updates and it is a pain to get them back in LAN only mode.
