This occurs constantly. If I clear the error and press the continue button in Studio, the H2D continues on its merry way printing my part as if nothing happened. I make sure the build plate is properly cleaned and wiped down with IPA before each print.
EDIT: I do not use gluesticks or any other type of adhesive so it wouldn’t be a lump of stick glue. Also, the H2D has not been modified in any way. I’m using the PEI build plate that was shipped with the printer.
Maybe the camera/sensor itself is dirty? No idea which one is used.
I agree with @technodanvan, my guess is also a dirty camera. It seems like the live view camera is the one used for foreign object detection from the docs (Introduction to H2D Intelligent Detection | Bambu Lab Wiki), so make sure that one is clear of any dirt/smudges and hopefully that should fix your issue
Make sure you have removed all of the foam packing from the inside. Had the same error until I discovered some packing I over looked.
I have 2 H2D, they both do it. One is a month old, the other is 3 days old. Nothing on the bed, 2nd printer is spotless, 1st is maintained well and clean. It’s something with the printer.
I feel like such an idiot. Yep… it was a small piece of packing foam that I missed. In the words of the immortal Homer Simpson, D’Oh!
Where did you find it? I also get an error, but everything seems to be clean
front corners near the top
A rather xenophobic warning if you ask me.
It’s a very small piece of packing material right underneath the main camera, partially blocking its view of the bed. I’ve included a pic for reference. I missed it because I wasn’t looking for something this small.
Check the other side in the front also.
OMG you are so right.
This was driving me nuts
Guess what I found?
Thanks for the heads up.
Thanks I missed them too.
Pesky little piece of foam got me too.
Fairly certain this got me too. It would be nice if, for example, its the very first calibration / set up, the error message indicates that it could also be some packaging foam that’s causing the issue.
Suggesting its something on the bed when it’s not can be misleading (fully aware why it would say this though)
