I’ve been printing for a month now on my enclosed p1p.
The other day while printing polycarbonate with the default settings of 100c bed and 280c nozzle my “front housing assembly” which is basically the fan on the toolhead that is mounted with 4 magnets popped out and the printer paused. The magnets that are on the toolhead itself were out of their place and attached to the front housing assembly.
I simply popped the whole thing back in place, pushed it hard and it works fine, except there is 1mm gap on the right side, possibly because the magnet didn’t fit all the way in.
Has someone else had a similar issue, either on p1p or x1c?
Will this be covered in the warranty, any thoughts on the failure?
I think this is a quite common issue. I had it on my X1C. I glued the magnet back in place a couple of month ago and since then the problem didnt happen again.
There are high-temp CAs that are good to around 250ºF if you’re worried. Normal CA, the bond will get soft at around 200ºF, but it’ll still be sticky and gooey and contribute enough additional friction to retain the magnets, I’d think.
CA starts to break down and produce Cyanide gas at around 330ºF (165ºC). That’s really the only temperature you need to be worried about, and I doubt the magnets in the cover can get that hot even on a long high-temp print job.
But if the magnets are getting that hot, there’s a different more significant problem to worry about - the Curie Temperature of the magnets. As they heat up, their coercivity goes down (how strong they are). As the magnet approaches its Curie Temp, magnetism goes to zero. That temp is much higher than the magnets will get (in the 300ºC range), but the coercivity loss is exponential and the magnets will start losing coercivity at temps as low as 100ºC. So a really long print job that’s high temperature may weaken the magnets enough to shake the cover loose even if the magnets stay stuck in their pockets.
Used superglue to secure my magnets on tool head today, printing ABS at a enclosure temp between 45 and 52 deg C and magnets started falling out. Seems to be working fine now
