MPCNC 3D printer starts printing – online


this is the most recent status of my MPCNC 3D printer. Everything is built from scratch. My first intention was to build it replacing all bearings with igus style bearings. But because of the special design of the middle part this is not possible (for now 😉

The middlepart needs these metal bearings to work rigid. The plastic parts spread a little bit when you put it on the metal rods. My igus adapter won’t. So: No chance right now to get this working.

But: The outer linear rods work very smoothly with them. So you can save 24 metal bearings and replace them with 3d printed igus adapters. After some more testing you’ll find these adapters on thingyverse.

At the end of the video you can see a little red sleeve case (printed on MPCNC) containing a odroid-c1+ with reptier-server running on it.

After activating z-probing in Repetier firmware the layers are perfectly growing now.

  1. Thank you, Walter. That is a very helpful hint. Well, the poor quality may also result in some bad settings of the repetier firmware. Some params have to be optimized. If that doesn’t help, I’ll try your suggestions.

    The parts for the glasbed holder are a modified version of The openscad files will be published soon.
    During the next days I’ll try it with a bowden extruder setup for colored 3d-printing with a diamond noozle ->

  2. that’s a nice extruder mount you got on there 😉
    What parts are you using to support the glass bed? I like it and would like to do something similar when my bed heater comes in.

    note: I designed the extruder mount with with the intention of it being used with the extruder throat run all the way up to the drive gear, this way the air duct will line up with the nozzle better, and aid in cooling.
