My Bambu H2C has experienced three instances of magnets detaching from hot ends, resulting in three unusable hot ends. In each case, the failed hot end had been working over the course of many prints up until its failure. I have found one of the detached magnets (the other two mysteriously disappeared) but there’s no way for an end user to reattach the magnet.
Is this failure unique to my machine? As I recall, it’s happened each time on hot end position #6.
This topic also exists for the A1 hot end. Someone erroneously replied to use Super Glue original formula gel to reattach the magnet because on the Super Glue website, it has the temperature range that it can handle as “ -650F to 1800F degrees (-540 to 820C)”, which is an error. The problem is that whoever typed the info for the webpage inadvertently added a zero to the end of each temperature. This error is evident as 1800F = 982C. Now if you remove the last zero from the temperatures, then they match. 180F = 82C and -65F =-54C.
