So about 2 weeks in with my new A1 and some 45+ prints in so far including ones from Bambu site & custom items I’ve designed. All print fine…
Problem I’ve seen is that the VERY first print I tried doing was the SD card benchy to see what a 17 minute print looks like.
Long story short, when it gets to the top of the wheelhouse and starts to get a layer or two from connecting the 4 wheelhouse posts - it snaps the print off the bed rather violently. Tried it with 3 different filaments, a Bambu brand new PLA and then a Hatchbox and Amazon Basics. Same issue all 3 times - same spot of the print.
However slice thru the Bambu Studio from a download - 47 minute print and it works absolutely fine - doesn’t pop off. Prints perfect.
For the most part all prints stay fine on the bed adhesion wise but in certain circumstances, I do notice that infills will also click when printing sometimes like Gyroid ones like its hitting the print and not staying up top. Could this be a bed leveling issue or something to that extent? I’ve run calibration tests and the like and it still seems to be doing this for Benchy every time failing.
How do you even troubleshoot such an issue?
might be some firmware changes that breaks the original benchy… maybe try to reimport it into the slicer from the sd card somehow to see what it does.
one reason for clicking ive found is improper retraction settings on the fliament, causing the head to leave a small spur when it changes layer.
bed adhesion (grease/heat) and warping can also be an issue that leads to the same issue.
there’s also a manual tramming guide in the wiki, where you manually adjust the bed to get it level.

Well remember the Benchy that comes on the SD card is the one I’m referring to which is that optimized 17 minute pre-sliced one that I cannot redo myself. Just threw the 3 models I kept into the PLA recycle bin I have and its uncanny how specific all 3 of these are failing in the same exact print spot.
I’ll try the tramming guide as I just saw that post about it last night and wanted to sit down and try this today. Maybe that’ll help here but ironically most of my prints have been absolutely fine otherwise but that’s probably because they have a far larger surface to adhere to the plate with.
Of course my plate I wash with Dawn soap, green scrubby and use IPA on it after to ensure it stays clean as it can.
