Extruder Assembly Choices
The Prusa Mk2S extruder instructions have 35 steps whereas the Mk3 extruder instructions have 66 steps, mostly as the later has more small odd metal parts.
I was thinking about trying to construct a Mk3 extruder assembly, but I'm put off for the moment by trying to source the odd parts.
If I had planned differently and had not bought a 5th stepper motor and a hotend already then
I could order this kit from aliexpress which appears solves the sourcing problem
tidily.
