Maybe I’m doing something wrong, but say I open an A1 mini project that uses a custom profile in Bambu Studio saved into the project, but I want to print on A1.
I go to the Prepare tab
In the Printer section at the top where it says ‘Bambu Lab A1 mini 0.4 nozzle’ I select ‘Bambu Lab A1 0.4 nozzle’.
It immediately and automatically switches to 0.20 Standard @BBL A1 profile while losing all the original profile settings, including critical ones like supports, brim, etc…
I thought it used to ask if I wanted to transfer the settings. Thinking I might have opted to suppress the confirmation, I looked around the preferences, but I wasn’t able to see a way to reset it.
Is this a bug or is my process for targeting a new printer incorrect?
Load the 3MF into Bambu Studio as normal.
Once it’s loaded as the A1 mini, then change the printer to the A1.
It should ask you if you want to transfer the settings.
I thought you were choosing the A1 first, then loading the file…which it should change it back to the A1 Mini…meaning you would have to change it back to the A1.
Ah no. I’m doing the simplest thing I could think of. I also tried a few of my A1 mini projects, but they all show the same behavior. I switch to A1 and all settings are gone.
At this point, since clearing settings did not restore the confirmation dialog, and I don’t seem to be doing anything wrong in terms of process, I think it’s a real bug.
Here you go. This is the original file I noticed the problem with but it reproduced with others as well. Please let me know and thank you for trying this.
We could also try the opposite. I could make an A1 profile and see if switch to A1 mini would show the dialog or not.
That should restore the query to Save, Discard, or Use modified values.
Leave the “Remember my choice” box unchecked to continue being asked about similar modifications.
Ok, I hope I don’t get this mixed up.
The A1 Mini shows the everything correct & slices fine.
When I switch to my own .20 Profile, it doesn’t ask me to accept different settings…so the supports are removed, but the blockers stay.
The A1 shows everything correctly also, but when I change from the A1 to the A1 Mini…it’s the same as above…no setting but the blockers stay.
Yes, that’s exactly what I’m seeing as well. Thank you so much for confirming.
There’s no confirmation dialog asking to move the settings over.
The blockers stay in the preview, but support and infill settings are lost and they revert to the settings in the default profile.
FWIW, it’s the same thing for other files that don’t use blockers. Switching to a different printer causes all custom settings to be lost.
Honestly when I looked at the model & sliced, I don’t see a need for blockers unless your worried about the bottom numbers on the wheels.
You might try removing the blockers & check Support Critical Regions Only…JMO
Yeah I know. The uploaded model has two versions. One without blockers.
But I’m not concerned with specific settings in this file. I’m just using this file to illustrate the point that the software has a bug in it and settings are not transferred from a printer to the next and results in the model NOT slicing correctly for the second printer. More obvious example.
@Tanklet I was wondering if you could confirm whether this is in fact a bug. I believe others are reporting similar issues that have to do with losing settings when switching to a different printer in bambu studio.
FWIW seems to work in some files, but not others. I can’t figure out the difference.
It seems to me that the profile settings are tied to the nozzle, which is tied to a printer type. I have an A1 and a P1S. On projects where I am using both printers, I open two instances of Bambu Studio, one for each printer. Otherwise I have to fix the settings every time I switch between printers. For the filament profiles, I have two sets, one for use on the P1S and one set for the A1. When developing projects, I tend to maintain two 3MF files, each with parts printed on each printer.
Using a .2mm nozzle requires another set of profile settings for each printer.
It also seems to me that things like brims, supports. and infill patterns tend to work better setting such things by object rather than in the global settings. That way the settings are tied to the object regardless of the nozzle or printer, and allows for better control and manipulation.
