My trusty old Wanhao Duplicator i3 Plus began acting up, so I decided to do some maintenance on the MK10 extruder. Had some issues along the way, but I got there in the end, more or less.
Disassembling the hotend is only possible while it's hot, which complicates matters. But often it just needs a new PTFE tube inside it, if you can get to it. The process would be the same for clones/rebrands, such as the popular Monoprice Maker Select Plus.
