Makerbot Reprap mk7+gen4 (Improved Version)
Description (By Makerbot Official)
This extruder was designed from scratch, and contains a number of custom manufactured parts.
We’ve learned a lot over our past extruder designs, and incorporated a lot of those lessons here: that’s why it’s smaller, lighter, and faster to build.
And since it’s designed from the ground up for 1.75 mm filament, it’s light-years ahead of past designs in small-filament reliability.
*More Stable Automatic Transmission Platform
*More dynamic Woodiness shell (Organic glass shell)
*Arduino Mega 256K
*High-performance MK7 RISC
