MCX? I really love the simple design of the MicroCube and I was looking for a more relieable movement system. I found the HyperCube Evolution to be a loved and very successful design, so I tried to get the best of both worlds. This printer is an evolution of the original prototype and prints a lot more reliable and cleaner. You can see it in action here https://youtu.be/z_v5L1m4204

Updates 2024/04 added cases for the electronics and the display

General Speed and vibrations have still to be considered with the rods compared to an extrusion based frame. It is possible to print with around 50 mm/s, you can of course try higher values and tweak the build. The usable print area for my build is 84x88x110mm. Smooth Rod Lengths for this version are as follows: X: 240mm Y: 210mm Z: 270mm X-Carriage: 245mm Diagonal Stabilizer Rods: 300mm

How to build? I mostly used the 8mm rods, T8 leadscrew and bearings from my Wanhao Duplicator i3 mini (rest in peace...) for the hardware and Nema17 motors. Also using TMC2208 drivers in standalone mode on a MKS Gen L 1.0 board. You can also use A4988 drivers with a Ramps 1.4 sandwich, have a look at the original MicroCube (https://www.thingiverse.com/thing:1938877) for a mount.

I'm also using the Mech Endstop 1.2 designed by MakerBot for all 3 axis and designed mounts for all of them. Everything is held together by M3 screws of various lengths. The hotend is a cheap chinese 12V E3D V6 clone and it can be used with a standard metal bowden extruder or a Voron Mobius.

The machine is using a removable, non-heated 100x100x3 mm mirror glass tile as printbed with a BuildTak sheet attached. It is based on my earlier designs and works fine for such a small machine. Details can be found here https://www.thingiverse.com/thing:3483100

I don't plan to write a build guide, this is basically a MicroCube with some parts borrowed and customized from the HyperCube Evolution - which both have excellent guides. I included the scad files for my own designs / modifications aswell as a copy of my configuration for the marlin firmware (1.1.9) and profiles for PrusaSlicer - just load the 3mf file to get printer configuration and print profile for PLA 0.2mm standard.

I would love to see someone improving this design or get inspired to build their own! Please feel free to write a comment if you have any questions, I tried to take pictures of all critical areas.
