(A1Mini) Bed plate moves before bed leveling

Hi All,

Sometimes the initial start of a print start moves my bed plate. Don’t no why this happen sometimes. Im using a flat plate with a shinny pattern for a nice surface.
This plate have a very tiny pit (looks the nozzle pushed hard into the material)

  1. Create a design (and today 22-aug-2024) changed a design in Fusion360
  2. Export the design and send it to BambuLabs Studio
  3. Do my changes as well in BLS
  4. Slice the plate
  5. Print plate

In the initial part suddenly the nozzle moves the plate. Then it start his bed levelling procedure.

I post this issue but in meanwhile im calibrating my A1 Mini and see if this will solve the issue.

Does someone have any idea why this happen? A benchy print from the SD Card went ok. After that the same STL export gives me the issue again.

When the move happen I pause the print. Move back the plate and resume. The bed levelling is starting and the print goes as normal.

I’m not understanding everything…Can you post a video…??

Hey there,

Here you are:

The sound you hear then the nozzle move the plate. In this video it didn’t. But the sound is the same.

There is no video, just sound.

EDIT: Had to download file to watch video.

So your talking about the nozzle parking on the plate & not on the center steel piece…??

What kinda of plate is that…??, it doesn’t look like a Bambu plate.
I would try it again with the Bambu plate & see if it works.

Same issue. The nozzle scratch over the plate. Now the original plate was places on the bed. It scratch and then it proceed the bed levelling. After this everything works like normal!

I don’t know how this happen. Many STL files I use don’t have this problem. But sometimes this happen.

Now this happen from a design Fusion360 exported to BambuLabs Studio.

EDIT:

Hmm…Tried it again. Used same STL file, imported in Bambu Studio. Send to printer. Now the same STL file is working without issues…
No changes made different then the export before… So exact same settings.
