Update: I've started working on this again and have decided to publish my latest designs as separate assemblies. The first can be found at Thing:3483883. I'm leaving this thing here as an archive.
I've been working on my Hypercube Evolution for a few months now off and on. I'm finally at a point where I've started mocking up the parts and feel like I can share what I've worked on so far. This is definitely a work in progress so please double check everything before deciding to use it. If you find an error please let me know. That said I've spent a lot of time trying to optimize the parts for easy printing and to use common M3 screw lengths.
A few important details about my build:
I'm using 8020 Inc extrusions (ended up replacing the 2020 extrusions with ones from Zyltech due to the 8020 having too narrow of a channel for standard hardware)
I'm going for a standard 300x300x3?? build volume. I ordered the Z extrusions 100mm longer than the spreadsheet called for
Utilizing 8mm (X), 10mm (Y) and 12mm (Z) linear rods per the standard build
The cast right angle brackets I'm using are from Amazon (http://a.co/5j6OLIc)
I'll be using a belt driven, single stepper, dual Z setup
It will be controlled by a Duet Wifi
It will be powered by a Meanwell HRP-600-24 power supply
I'll be using an E3D Chimera hotend, still undecided on the extruder
All of my models are either designed from scratch in the case of the unique parts or modeled off of the Inventor files provided by Scott3D (Thanks!)
Step files included for easy remixing! If Scott can provide them I believe everyone on this project should.
All parts should be in the correct print orientation. Some do require supports but not all. See notes below.
Once I have an operating Hevo I plan on editing this to clean it up and provide more details on the build. For now I'll just be sharing what I complete as each part is reasonably ready.
The XY stepper mounts and Y carriage are based on popular and I think very well done remixes. I've tried to get the correct attributions and remix links. If I got them wrong let me know. I took the basic concepts and applied them to Scott's solid models. They are not exact duplicates (though the Y carriage is close to exact), I made changes where I thought it made sense.
The Cast90_3030_Bracket_Insert I modeled to make it MUCH easier to install these brackets straight. They really help to align the extrusions. Support required for the tiny hollow needed for the tnuts to work properly.
8mm20T_GT2_Clamp was modeled because I despise using set screws to secure pulleys to the lead screws. If you use this make sure your slicer is skipping the half layer above the clamping area so it will break away when finished.
I'm pretty pleased with the way the XY_Idler_Mounts came out. The goal was to design a stronger part that wrapped around the frame so it could be positively centered and also to not use supports when printed. The thin connection in the linear rod clamp area will bend out of the way when tightened. Or you can cut it out, it's only one layer thick.
I'm still working on the details for my belt driven dual Z setup. I think the lead screw mounts I've posted will work for what I need though.
Let me know what you think. Any constructive criticism is certainly appreciated. Also let me know if you make or remix any of it.
4/25/18 - Lots of updates building up over the past couple weeks.
Completed my single stepper belt driven Z axis setup. It appears to clear everything and run smooth. Uses a 976mm closed loop belt.
I found the quality control on the 3mm 20T GT2 pulleys for the XY idlers to be terrible. The 5mm versions I have were much better so I printed some spacers to use the 5mm instead. They run true now. Use two per side with the flange butted together. No m3 washers should be needed.
Cut the zyltech 2020 extrusions to 200mm so modeled some 40mm MK2 heated bed brackets.
If you tighten the outer Z bearing holder screws too much it can cause the bearings to bind on the linear rods. To allow these screws to be left out or at most minimally tightened I modeled some right angle brackets that I mounted to the underside of the bed frame to help hold it together.
Finally a slight remix of the lead screw nut brackets to allow room for a Zyltech anti-backlash nut.
Any feedback on these updates appreciated.
4/23/18 - Corrected the remix attribution for the XY stepper mounts. I had a feeling I had it wrong then stumbled across MJ's collection of parts and remembered that's where I got the idea for how I remixed it.
4/22/18 - Of course since I put it in writing the z lead screw mounts needed to be changed. I'll upload the new setup once the longer closed loop belt I ordered comes in and I can finish mocking it up on the frame. I also ditched the 80/20inc 2020 extrusions. They have a 5.xmm slot which makes them incompatible with almost all 2020 hardware. I received my order from zyltech for replacements.
