Ultra-MegaMax: Dominator (UMMD)
Introduction
A CoreXY 3D printer being developed by Mark Rehorst at MMS. Already mostly finished, it has a 300 x 300 x 698 mm print envelope, is fully enclosed and will soon be heated for printing ABS reliably.
Completed/Has
NEMA-17 400 step/rev motors for X and Y axes, 9mm wide glass core belts
Belt lifted Z axis driven by an OnDrives Rino 30:1 worm gear reducer that prevents bed-drop when the machine is powered off.
Linear guides in all axes
Cast aluminum tooling plate bed with PEI print surface and 750W line powered heater on a 3 point kinematic mount
24V power supply plus two DC-DC converters to operate lighting.
Frame made from 40×40 mm t-slot extrusion
About 20W of white and 20W of UV LED lighting
Enclosure made from 8mm thick dual layer polycarbonate greenhouse panels
E3D Titan extruder and V6 hot-end

I can donate a QU-BD 1.75mm extruder to this project. It will need a Nema 17 motor though. — Pete Prodoehl
