This is a lengthy ReadMe that includes printing suggestions and required additional hardware. Additional components are listed at end, includingrequired Piezo Mount.

Update March 2 2019 Groovemount & Fusion Overhaul

• Now includes E3D v6 Groovemount Orion Mount
• Fusion Files updated for all v1.2 parts

• Mass centered over centerline (BMG filament path is off-center)
• Bracing for motor during travel moves
• Minimal supports required for printing
• Y-Carriage prints in 2 parts for strength and modularity; no supports needed
• Bring-your-own hot end, anything that mounts to the Orion lower-mount (currently E3D groove mount or threaded heatsink, Slice Mosquito) bolts into place
• Multiple part cooling fan options
• Full Fusion 360 project available
