I have a New printer (bambulab A1 bought this June) , with a fully updated firmware, and it has the same issue, it stops at 65% and says “print complete”.
I formatted the SD card, it printed succesfully, then the next print showed the same error.
Anyone managed to solved this issue? Yesterday on our day one with A1 mini combo, we had also the same problem: Printer got freeze at 85% and showed “print complete”. Nozzle and bed temp was still at printing levels but no movement at all. Print was sent to the printer from the app.
We still have 14 days to return it but I would like to know if there is any solution to this problem?
Same issue here. I just wasted 500g of filament because I have no idea why the print stopped or when it stopped to continue it 
Just got a new A1 a week ago and this has happened to me twice now. Printed loads of stuff already and had a 12h print as well that went well. Not sure what’s going on.
It says print it complete, but the bed doesnt cool down and the head doesnt return back to it home position. I can still see the filament stuck on the last object with the head. Restarting the printer results in the head moving and dragging whichever object is stuck to it.
Disappointing as it wastes a lot of filament 
Same problem here, second time this happens. 6 our print it’s stops mid print and says it completed. Nozzle still at mid print distance. Print send via pc. Had this printer for less than a month. Will try another sd card. Wasted a lot of filament!!
Same issue. I think I will be able to cut of the print and continue it and glue it together afterwards but not fun first experience.
Same problem on A1, it failed 3times today, one after another. Did anyone figure it out?
Hey, Few days A1 has been interesting. Display change mode by it self during the printing. Display jumps from printing view to control or displays previous printings. Touch screen is difficult to handle as well. Also print stops it self as a completed.
Firmware was updated to 01.06.
Now I downgraded it to 01.05.
Display works as it should be. Touchscreen works alao.
I have 12 hour printing on goibd present and after 25% ok.
Will see.
Cheers
Not working. 52% done. I arrived home and display showed nozzle temperature setup screen with number 6 entered, waiting other digits or ok.
I pushed back arrow.
After few. Minutws printing was cancelled by it self. Like a ghost is pushing the buttons.
Then I started to downgrade firmware into .04 and downgrade stopped at 32%.
Wonderring what to do next.
Cheers
Power off and on.
Factory reset with .05 firmware on going.
Next printing again.
Will see.
maybe the stl is the problem in my Situation was the stl the problem
change some setting in bambu and slice a agian
I have had the same exact issue several times. The last time the fan was still blowing loudly. The nozzle was stuck to the model and since the nozzle was still hot and cooling I extruded the filament back out when it got a little cooler and did a nice cold pull which looked very clean. No idea why this is happening.
I had the same problem. Print stopped half way done after about 30 minutes. The tip was stuck to the model. The plate was still warming but the tip wasn’t, so it knew it wasn’t printing. No errors, it just said print complete. Fans were all going. An hour before I successfully completed the exact same print, and this was a reprint, so it wasn’t the settings.
Having the same issue. Some prints are fine but then on other prints it’ll just randomly stop and say it’s completed. My handle stopped at 64% and said it’s all good.
I’ve recalibrated it and factory reset it but it still keeps happening. Any advice would be greatly appreciated.
I have this issue every time I leave the printer doing some larger print and the “it is lubricating time” prompt apears. Just last night, a 12h51min print failed at 12h10min mark because the printer decided to have a lubrication session. It always stops the project and says in the Bambu Handy app that print was succesful, and like 78% or similar. Then it resets and is ready to print. Unit is New, and with newest firmware. I suspect the Lubrication prompt has some timelimit, and if it is not met, it just cancels everything.
Ad the same issue today, Did Bamboo at a solution ?
