Assembling Original Prusa i3 MK3S – Part 4: E-axis – extruder (long version)

The fourth part of assembling Original Prusa i3 MK3S.

I am just following the instruction provided with the 3D printer and trying not to make too many mistakes. As a result I’ve reached the end of E-axis assembly in 3 hours and 40 minutes.

This series will be splitted in parts just as it is in the manual. That was the toughest part in the entire build. I’ve made a terrible mistake that took me an extra hour.

I’ve forgotten to assembly extruder cover, which lead to disassembling the whole part. Unfortunatelly I was unable to remove one of the M3x40 screw because of crooked nut or broken thread and this alone took me 45 minutes. Beside I’ve encountered two tricky parts: Pushing nylon guide filament and X-axis belt assembly.
