Alright… can someone explain to a non-Bambu guy….
Why they designed a cover that was so prone to falling off… as to warrant a sensor or whatever to detect it, instead of designing a cover that just doesn’t do that?
I was monitoring this print remotely (Bambu P1S), so I'm not sure what actually happened. It's possible that it failed for other reasons, and then the tool head got tangled in spaghetti and disassembled itself.
Hmm. that's plausible.
But it's still enough a problem that they programed an alert for it.
which means it's enough of a problem had a way to detect it.
feels like a case of not fixing the problem.
I think it's a good added measure to stop a print, in this case something caused the spaghetti, it would have kept causing spaghetti but the cover popping off stopped the print. I've got about 400 hrs on my p1s (upgraded from p1p), and I've never had the faceplate pop off. I would guess this is an isolated incident.
Coult be AI generating the message. Just kidding
All hail the robot overlords.
It's held in with two fairly strong magnets, I don't think it falls off on its own. If a print falls over and catches on the extruder it could push the front off. I've had it happen for that reason.
Personally..... I'd just have left it off if I was them. I can't imagine a little plastic shield helps hot end temps
depending on the design, it might be to control air flow around the hot end's cooler block.
it's usually best to have some type of duct go from the fan and around the back of the block rather than just being open air- it keeps the air contained until it does it's job. But again, the only Bambu I saw was at microcenter and I was in a bit of a hurry so I didn't get a good look at it.
I've printed on mine for nearly 1000hrs now, never had an issue with that or prints not sticking. Just have to prep it well and make sure there are no scraps under it.
Normally the toolhead should never hit any object. If it does, and the cover detaches, it can be detected and the printer stopped before any significant damage is caused. Fallen off cover > broken machine.
The cover needs to be detachable to change or replace the hotend, and you need to have the cover for basic protection and better airflow control (I assume), and it's best practice to have a sensor to protect from user error. If the sensor is already there, why not also use it during the print?
