I have a Creality Ender 3 Pro printer, and just installed the Micro-Swiss All-Metal Hotend for CR-10 S Pro. After installing following the video instructions by Micro Swiss and Teaching Tech, I set it to print a good old Benchy.
Was working fine, until about half way through it blocked up.
The stuck filament appears to be trapped, even when heated to 230 °C, which makes me think it may have melted into a gap somewhere and cooled creating a block. I am using Filamentive PLA.
My questions are a) how should I remove the filament fully without damaging the thermistor and heating element and b) what do I need to do to avoid jamming?
