Started a print from Bambu Studio, startup went fine, including bed leveling. Purge line printed normal. Then the printer began completely ignoring the actual print I sent to it, and went the the front right (doorhandle) corner, to the very physical edge of the plate, and began badly gouging and dragging along the plate in long lines. In the process of troubleshooting, I began having problems with the AMS not responding, and not being able to access the SD card. I rebooted everything, reset the printer to factory defaults, resliced to print, finally got everything running and resent the print. Same result.
This is not a bed leveling issue, or a clogged print head. It’s not a Z axis issue, as the print head shouldn’t even be going near that corner, and it’s not even trying to print the actual file. As far as I can tell, it’s not even doing any extruding while it’s gouging, though that may just be because it’s dug so hard into the plate that the filament can’t get out.
I don’t see how it could be a corrupt file giving bad orders to the printer, since I re-sliced it, creating an entirely new file. I’m at a loss, as none of my searches came up with anything like this issue. I’ve put in a support ticket, but my reading here hasn’t given me high hopes for that avenue.
That looks pretty bad, just a quick suggestion. Could the nozzle be really really bent? I mean probably after that but it is good to check, even if that is not the issue.
I thought I read somewhere to turn off plate calibration (or something like that) with those 3d plates on Bambu website. I believe it is different then bed leveling and uses that bar code on the plate? Fairly new to this so a pretty vague answer and take this info as is, probably wrong but just an idea Hope you can get it solved.
How many hours do you have on your printer? It could be that the SD card has gone to the SD card heaven and needs to be replaced, especially if the files are becoming corrupted. Because of how the printers use the SD cards, after a while they can start corrupting. Reach out to support aswell, this shouldn’t happen and those buildplates are essentially fancy bits of metal now.
I have one side of the stock P1S plate gouged in a similar manner, did a bed levelling just like you then mine gouged the purge line permanently into the plate, no the plate was not badly aligned and the correct one was selected.
I was scared to start another print in case it did it again but( touch wood) it has not happened again, still to this day I have no idea why.
Thank you for your response. The first one was on the Bambu Smooth plate. It was a routine print, and I hadn’t done anything special or different prior.
Thank you for the reply. I will certainly look into replacing the SD card, but I don’t think it was the cause in this case.
I’ve had the printer less than a month. Also, I crossed my fingers, flipped the effect plate over to the textured PEI on the other side, and ran 4 successful prints staight from the BH app after posting.
I had printer do that to me but it was a firmware/software problem.
A word of advice. Use the damaged plate until you figure out the problem. Don’t ruin all your plates
Hope you can get it solved.
