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
I just had the same thing happen to mine. Had it for 2 weeks - printing daily and gone through 4 spools of PLA - no issues was working beautifully. Then this morning when doing the Leveling (I run it before every print) it made an odd sound when the print head returned to the back side of the printer and as it moved the bed up to the head on each pass it started gouging into the plate. Did it three times before I had to turn it off. Rebooted and ran a full calibration with no issues - it spits the poop out just fine but when doing the bed leveling it keeps moving the head up until it starts to scratch the plate. Went through each ise of one plate and started doing it on my CryoGrip plate that arrived today as well.
Man, really sorry to hear that. My issue turned out to be a bad SD card, as someone mentioned. It was corrupting the files sp the printer was working fine, but following crazy instructions. I contacted CS and they offered to send me a new card. I had to demand an answer about the destroyed plates and the nozzle, which got bent. They ended up sending me a complete hot end, a couple plates (though they didn’t replace exactly what I’d bouht) and a new SD card I won’t use, because it’s the same garbage they come stock with. I ordered a Sandisk card which is much larger (memory) and actually works. No issues since.
Make sure you stay on them to get replaced what they fausee to he destroyed. Unfortunately, i don’t see any chance they’ll replace your Cryogrip, which js a crime because it’s probably the best plate out there. Maybe you can get a credit for it, or one of their cool plates.
In case it help Bambu figure it out. Normally the printer goes to registration marks off the right side of the print plate, moves to the straight to the back of the printer, and then moves diagonally to check the print plate markings. When I had the problem it went from the registration marks on a diagonal directly to the print plant marking, and crashed in to the plate. Cycling the power seems to be the fix, though if you are like me you trashed one side of two plates before doing a ‘have you tried switching it off, and back on again’.
Hope you can get it solved.
