I just had my first clog, due to selecting a PLA spool for an ABS print. Upon disassembling per the online instructions the entire connector socket for the extruder tore off the PCB, traces and all. I’m pretty careful with this kind of thing, so I expect lots of other folks will have this situation eventually.
Note that this is one of the plugs that is glued to it’s corresponding socket, but I even cut that glue loose as best I could.
Anyway, I’ll order e replacement board and a spare extruder, but maybe Bambu Lab could consider adding epoxy or similar to the base of the connectors on the toolhead board to give them a little better chance of survival during disassembly.
That’s one area where I think they could make a slight improvement when it comes to swapping the toolhead and making it easier on the customer.
I’d like to see them sell a daughterboard quick-disconnect kit. There’s currently 3 plugs in a tight-spot the user has to unplug to get the hot-end out - having a single quick disconnect (button disconnect or magnetic disconnect) connector in the middle would make this way easier on the user and reduce the risk of this type of issue occurring to the on-board receptacles.
I’m not sure if the toolhead as the connection to the BUS of the printer, but an added benefit could be to add an identifier chip (or jumper headers) that tells the printer what toolhead is installed (e.g. 0.4, 0.6, 0.8, hardened, etc.). Allowing for catching inadvertent errors, like they do with the build plate scan.
