Front Cover of Tool Head Falling Off

Bambu Lab X1 Series Troubleshooting
21

I have a brand new X1 Carbon. Just had the same issue so came here. I’ve had the printer set up for 2 days. Printed first 3 things with PLA. All worked perfect. Printed a small cube with ASA, was perfect also. Started a bit larger ASA job and it did this about 75% (1.5hrs) of the way through. After reading everything here I’m going to assume it’s the magnets giving out from the high heat. Going to try the methods suggested above to try and makeshift tie it on. But just wanted to add to the list so they might get moving on a proper solution.

Same here. It looks like the printer is somewhat loosing steps and doesn’t know the position of the print head in this last movement to get to the filament cutter in the front left.
Mine is violently moving to the cuter, misses it, pushing of the front cover, moving to the front right and snapping the cover back on. Then back to the filament cutter and is now in the right position.

I used two strips of duct tape to hold it in place

if you get this notification but your cover does not fall off and all screws are tight and connectors in place than this might be your fix:

i was able to fix it by simply placing another magnet behind the one that is responsible for the hall effect sensor.

Seems like the magnet is not strong enough to trigger the hall effect sensor continuously.

Having the same issue. Specifically when printing something that takes up a large amount of the print area.

For example when printing the 6x6 gridfinity base plate the tool head would aggressively slam into the front top left of the P1S enclosure. A small sprint loaded bracket would spring out of the way when the tool head went from right to left. But when the printed would go from left to right in that corner it would have a serious failure and rip off the tool head.

Duck tape is not a solution. The magnets are not the problem. The bambu slicer used my p1s preset. Not A1.

A legit solution would be appreciated.

Tengo el mismo problema, alguien sabe como solucionarlo?

I have the same problem as the original posting person. I initially though I changed a setting within Bambu Studio by accident while fine tuning profiles for other filaments there. But even full resets did not change anything. I tried so far:

  • different big and small models (all sliced with Bambu Studio)
  • during calibration of a print it gets to the front left corner and hits off the cover
  • tried factory reset the X1C itself
  • tried reset everything in Bambu Studio
  • deleted and readded the printer in Studio
  • also tested one of the pre-saved models with the same result

Baseline is I cannot print anything at all currently

I had the Panda Touch in the USB slot, took it out, No longer having the problem. Thanks

My printer is 3 days old and has been doing this at the end of the print. Now it is doing it anytime it goes near the front L corner. Anyone have a reply from Bambu?

I’m having the same issue with my new P1S. Four days in, the printhead cover keeps flying off. I’m trying some duct tape now. Very frustrating.

33

and it still fell off in the left corner.

34

For anybody else who may benefit from my fix, check the tape and foam on the inside that covers the board in the back of the display. After adding a light bar, my tape was in the wrong spot. That was enough to bump the tool head cover and trigger the sensor even though the cover didn’t fall off.

Once again, hoisted by my own retard!

I am now after 600 hours of printing having the same issue! After a flawless print the head moves too far forward then to the left and slams into the left front corner!!!

This is exactly what was happening to mine. The Foam and tape behind this board started coming loos and sagging a bit. It sagged just enough to catch the print head as it was going by and would knock the cover loose. Thanks for the tip!

41

I have the EXACT same problem, the printer is literally brand new, first print test and it does that initial stages. any fix?

42

This is still an issue and personally i feel is a design flaw. I am tired of wasting time and filament!

43

I’ve not been able to print a single thing…. On a brand new printer

Welcome to the forum.

Does the prints that come presliced on the SD card/printer memory print okay?
