More Serviceable Extruder
My MK2S had detachable extruder head for easier maintenance. With upgrade to 2.5, most of the parts became obsolete so a suitable upgrade was needed to match 2.5.
The original MK2S design
I'm currently testing two designs for ease of use. Input welcome.
U-bracket design (R2F)
Scarab design

Re: More Serviceable Extruder
Revision F "U-Bracket" takes 0:01:56 to completely remove extruder assembly.
Revision G "Scarab" takes 0:02.44 to completely remove extruder assembly.
Rev F was kept for normal use though much more clumsy to reassemble, Rev G hid too many pinch areas that accidentally crushed wires while F didn't.
If I were to take another pass at this, the best features of F and G could be something worth testing. Considering the extreme limits on space and the design of the MK2/3, a detachable assembly using only off the shelf (standard) connectors, I'm satisfied with a 2 minute detachment time.
