Problem: Bambu Studio Prepare tab does not update after filaments are changed in AMS
Studio Version: 1.8.4.51
Platform: MacOS
Steps to reproduce:

  1. Open Bambu Studio
  2. Go to Prepare tab
  3. Change some filaments in the AMS
  4. The filaments available in the Prepare tab does not refresh and remain stale. The user must remember to go to the Device tab and then back to the Prepare tab to manually refresh.

There should be a callback within the system to keep things updated even if the Device tab is not active so that filament information that is shown in the Prepare tab stays up-to-date. Otherwise, the user may slice with the wrong filament.

Problem: Bambu Studio crashes shortly after launching after the recent update
Studio Version: 1.9.1.66
Platform: Windows 11
Steps to reproduce:

  1. Open Bambu Studio

Other information: Windows 11 Ver. 23H2, i9-12900K

Same issue here, curiously I’m using the same kind of CPU on a Asus Z690 motherboard. I know that I get at popup regarding BambuStudio not playing well with NahimicOSD.dll for a while before the newest build.

Problem: Impossible to change any option excepting “Cooling overhang thresholds” in the Filament settings
Studio Version: 01.09.01.66

If you have parts that are using adaptive layer height and you go to select more than one of the parts and then copy and paste them, the resulting copied parts do not have adaptive layer height applied to them.

If you individually copy and paste parts with adaptive layer height and paste them, then the copied parts do have the adaptive layer height applied. It seems to only happen when attempting to copy more than one part at the same time.

Problem: Bambu Studio crashes when opening the select model dropdown
Studio Version: 1.8.4.51
Platform: MacOS
Steps to reproduce:

  1. Open Bambu Studio
  2. Create a new project
  3. Click Printer Type and Select “Create Printer”
  4. Click “Select Model”, without selecting Vendor Type
  5. Experience the Crash

Other information: Mac OS 14.3.1, MacBook Pro 13" 2020

Welcome to the forum.

Do you experience the crash with the latest version of Bambu Studio?

Problem: Print by Object Exclusion-Zones not right - Toolhead crashing!
Studio Version: 1.9.1.66
Platform: Windows 10
Steps to reproduce:

  1. Open Bambu Studio
  2. Create a new project
  3. Add two Objects of your choice
  4. Change Plate-Settings or General settings to print by Object (doesn’t matter which one)
  5. Move one object closer to the other one.
  6. Observe the outlined circle of the exclusion-zones. Overlap them by approx. 10mm (1 square on the buildplate).
  7. Hit slice - It will work and allows you to print.

Other information: If you move the object until it causes a fault and doesn’t let you slice, check the purple outline - The overlapped area is way smaller than the original overlapped area shown.
From the grid-view it looks like the calculation of the exclusion-zone is 5mm-8mm shorter than it should be? You can count roughly 3 squares in purple (30mm) but 3,5 squares (35mm?) in the grey area.

I believe I was able to replicate this:

That behavior does seem different than before, with the overlapping grey outlines in screenshot 1 I would have expected the slice to be refused.

Problem: Z-Slider in preview shows wrong height values
Studio Version: 1.9.1.6.6
Platform: Windows 11
Steps to reproduce:

  1. Open Bambu Studio.
  2. Select 0.2 mm Standard Process.
  3. Add primitive “Cube”.
  4. Slice and see z-slider in preview - at layer 1 it shows the correct height of 0.2 mm.
  5. Enable “Scarf Joint Seam”. Slice again, and the z-slider will show a wrong height for first layer and all other ones.

Don’t know if this is important: the configured printer is in “LAN” only mode.

I have experienced this myself and also tracked it to the beta feature s are as you have.

It reliably causes the layer bar to incorrectly report the layer information.

It sometimes report a layer of zero 50 layers or higher up.

LAN mode is not related in my testing as I have never enabled LAN mode.

Yes, the crash also occurs in Version 1.9.1.67

Problem: Pin to Start lacking proper icon
Studio Version: 1.9.2.57
Platform: Windows 11 Pro (23H2)
Steps to reproduce:

Update Bambu Studio to 1.9.2.57.
Icon in Windows Start menu is generic.
Delete shortcut and re-create does not resolve.

We use Bambu Studio every day, all day, and end up closing (GPU usage for video) the app when we aren’t actively watching things. So that icon gets a lot of visibility. This just started happening with the latest update.

Desktop and Program icons are fine. It’s only the Pin to Start icon.

Just updated to version 1.9.2.57 and the AMS Filament diagram seems bugged with the lines. Not a big deal, just a graphical glitch. I rebooted but still exists.

The bottom left spool no longer connects it like is offset up and same with the side roll it offsets a little. Like I said no big deal just something that caught my eye right away lol.

I believe this has been fixed in the latest BS released today.
