My linear y-axis rail recently started clicking and Bambu support helpfully shipped out a replacement.
When going to take the heat bed off the printer to replace it I’ve discovered that one of the screws is completely stuck, and even the most careful removal attempt is stripping the head. I’ve obviously gone back to support as it’s not even two months old and hasn’t been removed before but anyone got any tips for removing a stuck and stripped screw at all?
I’ve tried the obvious things like a rubber band/glove in the hole, torx instead and can’t grab the head with any pliers as it’s below the bed height.
I had to pull my bed off when filament got stuck in the rail slot.
The bed screws should be level with the plate, so you can’t screw up from the bottom…but there is enough room to get a small saw blade inserted.
You would have to cut through the spring, then the screw.
If it’s on the left side it should be pretty easy, the right will be a little harder because of the base.
Thanks, I thought I might end up doing that in the end. Going to try tapping a flat head screw driver into the top of the screw first and see if I can get any purchase.
If you do end up cutting it, you can get the spring from the A1 Screw Kit. The bed screw you’ll have to find yourself.
Unless of course Bambu could send them to you.
If it’s a hex socket head screw (or pozidrive) then you could use a drill, larger diameter than the the screw shank, but smaller than the head, and ‘drill out’ the head. That will leave, on lifting off the bed, a short stub of the screw shank that should be removaable with pliers. (for larger sizes, you can get reversed twistdrills, which as they cut in, they screw out the bolt)
Thanks! I managed to sort it, tapped a flat head screwdriver far enough into the head to get purchase and get it loosened. It was properly stuck though
