Overview

Builds on the D3D v19.02 3D printer.

Features

Eco edition - insulated heatbed for 30%-60% lower energy consumption while printing with heated bed
Upgraded to 24V control system
Silent stepper drivers - uses TMC2208 in legacy mode instead of A4988
500W heatbed for 1 minute bed heatup time
Added built-in GFCI electrical safety breaker as a standard feature
Still uses the Titan Aero extruder with 3 mm nozzle
Auto bed leveling with babystepping correction

Future Work

Dual extruders borrowed from LulzBot TAZ Pro
Supervolcano Nozzle add-on
Rubber optimized extruder - see Rubber Extruder

CAD

Hint: Tasks: (1) Updating Y axis holding bracket including 3D printed Corner Fit. (2) New insulated bed. (3) 3D Printed Control Panel. (4) Offset cable chain start piece.
