I make only very slow progress: https://www.youtube.com/watch?v=40GhRyhDb0o

UPDATE 5. February: Assembled Y axis.

UPDATE 2. February 2018: Assembled Z axis.

UPDATE 19. December 2017: I started the build and added a picture from the frame.

UPDATE 3. December 2017: uploaded a design change. I will use now a 5" display that shows the TouchUI from OctoPrint instead of the MKS TFT32. The display is connected to a Odroid C2. I even managed to allow my future HEVO to access my NextCloud. No need to upload files anymore.

The first orders are out and I expect the parts for the frame to arrive soon. On demand I will publish some pictures on progress.

===================================================================== UPDATE 16. November 2017: Added some more parts and a picture of my planned HEVO. To get more room for cables and bowden tube I lifted up the top frame. So the changed parts will not get mounted to the L brackets. Instead I use normal M5 screws and hammer nuts. I only reduced the M6 hole in this parts to M5. M6 Screws are not needed anymore.

===================================================================== I am only planning my new HyperCube Evolution. I like the design very much, but I wait for budget clearance from the finance minister. So I used the provided Excel spreadsheet to calculate the parts and assembled them virtual in OpenScad. I wanted to know how it would work with a normal lead screw attached with a coupler to the stepper instead of using a stepper with an integrated lead screw. It worked not so good with the sizes from the spreadsheet and the standard parts. I have found a way to have a build height of 470mm with a 500mm lead screw. You need a little bit more Z extrusion length and a new Z axis linear rail bracket. This bracket prevents that the bed crashes into the motor coupler. For the 500 mm lead screw with a 470 mm build height you will need Z extrusions with 690 mm length. In other words: add 20 mm to the length of the Z extrusions calculated by the Spreadsheet and use this part. Be aware that I have not verified this in reality. As I will put the electronics in a room under the printer I will add some tens of millimeter anyway.

If the height of the rail clamp doesn't fit for you: There is a variable in the beginning of the scad file that allows you to adjust it.
