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

Uncompleted Tasks

  • Add heater to enclosure to get the temperature up to 50C for printing ABS

The Digital Dentist has taken quite a lead with this project and scrounged up parts to build a basic frame and put part of an old CNC machine on it. — Pete Prodoehl

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