My P1P is a huge pain in the butt. I upgraded to a P1P for Christmas. I got it home on the 9th. Anyway, I woke up this morning with the front “shroud” I dont even know what you effing call it, on the floor. Its the front cover that goes on the hotend and has a fan on it.
I went to plug it back in but the stupid fan connector is broken. What do I even order to fix it? Im very unhappy with this printer so far, I think it’s been down as much as its been up and working.
The entire reason I upgraded to this printer over a my old bed-slinger was to get around the constant need for babysitting or tinkering, and yet I’ve probably spent more time troubleshooting this machine than printing. Between having to disassemble the entire machine because a screw fell back beneath the “poop chute”, having to disassemble the entire extruder assembly to remove a piece of caught filament in the gears, to having the GD, front plate with its weak magnets constantly falling off, now resulting in me having to buy a replacement all in under a week, Im really beginning to regret my purchase.
Not to mention, gettin support or trying to contact Bambu seems impossible.
Have you recently changed your nozzle? I found that if you don’t properly feed the wires back into the retaining clip they can put enough outward pressure on the cover that the magnets don’t hold as well.
I changed the hotend to a hardened steel one, and I also had to disassemble the extreder on like the 4th day I had it due to a small pc of filament breaking off in the gears, causing the extruder to be unable to grab onto my filament. I made sure though that I fed the wires back properly through the retaining clip. I’ve had an issue with the cover falling off when the printer is printing since I got it. As though the magnets were weak and the natural vibrating the printer often does while printing is shaking it off after a couple of hours. I shouldve just wrapped it in kapton and been done with it.
Firstly, it’s not just you. This has been reported by others and also happened to me.
I’m not a fan of the way that they wire up the nozzle. There wasn’t enough care taken in designing cable management in my opinion.
I was lucky though in that when it happened to me it was while I was standing there so I was able to hit the pause button before any real damage occurred. On closer inspection, my re-layout of the cable after replacement of the hot head apparently wasn’t “just right”. That’s because it was pressing up against the cover just enough to pop the magnets.
Whereas, I like the idea of magnetic hold of the cover - use magnets extensively in my designs - Bambu needs to get this right. Right now, there is too little design precautions to ensure a fool-proof attachment as we’ve seen reported just now by you and by a lot of others. One option would be to allow for a hasp or a clip to reinforce the magnets.
However, I’d be judicious with the use of Kapton tape in such an application. You gotta remember that Kapton tape and it’s adhesive was actually first developed for laminating bar codes onto PC boards that had to survive a wave solder process. In other words, it supposed to be hard to remove and you may be buying yourself a different kind of headache when you want to service it in the future. But, YMMV.
