I just to switch within the program to .4 nozzle on the left then all my filament and process profiles disappeared. It automatically switches my printer as well to the stock …

Yeah that makes sense. I’m not at my computer at the moment but when I get back to it I’ll poke around the process files and see if there’s a way to make them more compatible.

Yeh but within process settings all I should have to do when I change a nozzle size is change the line width. Like I should be able to change the filament or nozzle and then just sellect a custom process profile and make one little change and thats it but they expect me to recreate the entire thing …

I’ve never had a saved 3mf file abandon it’s saved settings without my input - the file format forbids it, it creates copies of machine,filament,process inside itself - you can save project-level configuration to a 3mf with confidence. The slicer’s method of storing it’s user config is completely…

I just tried to open a project using a .6 Nozzle. Everything opened correctly but if I switch to .4 nozzle then it removes my filament and process settings. It says my custom filament profile is unsupported and my process settings are set to generic only. So that means I would have to completely re…

[image] Beacon: Even if I had to change all the setting per filament within filament that still doesnt fix my issue. I should be able to have all my process profiles be universal because there is nothing in there that says what size the nozzle is. I do not fully agree with you though, because…

I guess I am just spoiled coming from cura because it allows you to change any one setting and create a new profile off of that without filling in every field again. Unfortunetly nobody can tell me how to use cura on a h2c.

It doesn’t survive the diameter switch. I agree that different filament profile settings are related to your nozzle size so maybe I could see needing to create a new filament profile each time. But your Process profiles have zero things in it that should make it married to the filament profile. If t…

[image] Beacon: But your Process profiles have zero things in it that should make it married to the filament profile I find that to be the opposite, but I agree that the current layout is maybe too fragmented for its own good. Some examples would be transparent filaments really like also hav…

There is definitely a relation between the process profile and the nozzle size. 0.2mm layer height for a 0.4mm nozzle requires totally different settings, than 0.2mm layer height for a 0.6mm nozzle. That in combination with the different filament profiles, makes management of the different fairly …

Creating a universal process file This will create a process file that is compatible with all existing Bambu printers First in Bambu Studio create a custom process profile. I called mine ‘universal-process-profile’ and set the Walls count to 5. [image] Now navigate to your BambuStudio user proce…

BS making me recreate every profile when I change nozzles

I wrote the post originally as answer for this thread, but it got way too long and maybe more useful standalone, so I’ll just link it:
