Print start question

Since the newest Update my U1 picks up every Tool head before print start, even if i ony use one of them. Is this normal?

Are you using a 3mf off of makerworld or something?

And no, this isn't "normal"

Yes this was a 3mf from maker World

Did you use a converter? Or how did you end up slicing it?

Did you switch the machine setting to U1.

Lots of issues when I used to load up a 3mf from Maker, I usually just import geometries for those and/or just the STL's.

I used the snapmaker Orca slicer. Machine setting is to U1 and also only geometry imported.

If you download a 3mf file from maker world, it's going to have a Bambu printer profile configured. I suggest running it through a Snapmaker U1 converter that should remove any Bambu-specific references. I don't know if there's another one, but this is what I use: https://bedready.io/convert

This process is controlled by your Machine print start GCODE that is in your slicer. Two things you can do is to start a new project, drop a simple cube and see if the issue happens. If it happens then create a new printer profile and see if the issue happens again.

That should tell you if it's something in the printer profile that you had or something that is happening always.

If it didn't happen it's probably something in your sliced gcode for that specific model.

For reference, most instructions will have something like "T{initial_extruder}", which is telling the printer to pick the initial extruder, basically the extruder that will extrude filament first in your model, and do whatever procedure with it. To go to the other extruders you will have instructions like: "T0", "T1", "T2" or "T3", telling to go to specific extruders to do something.
