Unfortunately the fan bracket popped open during a print last week and a good 3 hours worth of filament accumulated and backed up into the print head of my UM3 extended+. This left a fairly significant blob of polywood stuck in and around the print head and extruding nozzle.
I've cleaned the worst of it away using microshears and files and now there is just some gunk left in some hard to reach and fiddly places at the back of the nozzles where the wires are. Ideally I would like to remove the AA print core to finish up the clean up operation but due to the accident there is now a loose/dirty connection with the print core. Therefore, before I'm able to scroll through the menu to remove the core, I get a max temp error and all menu options disappear and I'm unable to proceed. My only option is to switch off the printer.
So I'm asking for some advice regarding my next steps and options... Is the only way around this to disassemble the print head? I haven't done this before (although I'm happy to give it a go!) so my worry is that I will spend time disassembling the print head and I still won't be able to get the print core out! I guess this is not the case but I just wanted to check. Any other suggestions/options are also very welcome!
Thanks in advance!
