Vevo - Hypercube Evolution Frame conversion to Voron 2.4 R2

The design is fully tested but the documentation is work in progress, Please message if there any queries. Last edited 24\09\23.

I am not quite sure if this can be classed as a formal remix and if I classed it as such, would it confuse things? I therefore want to give full attribution & credit to the Voron Design Team for the original Voron 2.4 R2 design, documentation & their awesome, open source design work in general.

My side mounted exhaust mod is based on this great Voron mod. The original works perfectly fine, I have just added additional lid fixings and reoriented the part to print a little better IMHO. I will publish separately as a remix.

Conversation Costs

Some first thoughts regards this conversion. You will only be really retaining the Extrusion Frame kit from the original HEVO (unless you are already using Klipper and can reuse the RPI).

You will not be able to reuse the existing controller board unless it can control 7 stepper motors individually for use with the QGL(Quad Gantry Levelling).

Individual Nema 17 Stepper Motors may be reused but not ones with integrated lead screws. Better to have four matching stepper motors for the Z lifts. High temp motors are better for the X&Y motors within the chamber.

Undertaking this endeavour you will be certainly saving approximately $150 on the frame but you could also spend at least another $700 to $900 on additional items, dependent of specification to complete this project.

This is still very good value compared to some higher end kits available but still a significant expense. The expenditure just needs to be considered before undertaking this project. Things can get out of hand, you have been warned!

Please comment or message and I will attempt to answer in short order.

I am not wanting to reinvent the wheel with this publication. I have included a full Fusion 360 file to illustrate the general assembly of the conversion but will upload the BOM & the STL files to those that are different to the magnificent work the Voron Design Team have already created in the original BOM, Manual & STL files.

If any of the Voron Design Team have any issues with any of this or any form of attribution\license, please let me know and I will adjust asap to suit accordingly.

I have noted where there is a specific changes to fixings and to what size. However, I will not list all the stock fixings in the original manual or BOM, only the changes.

I have also designed various additional mods for the Vevo such as a Pivoting top mounted display:

Stock versus Bespoke Parts

The majority of the parts are as stock except for the odd bolt here & there. The major change is the use of MGN12H Linear Rails to the Z axis because the 3030 extrusion slot is to large for the stock MGN9H rails to the Z axis. The design still retains MGN9H rails to the Y axis and a MGN12H rail to the X axis but both are different lengths to the stock V2.4 300 design.

There are also 3 additional lengths of 2020 extrusion required for the XY Gantry. Two of the existing 2020 HEVO bed supports can be reused for the Build Plate support but will require some additional square washer to make up 6 mm over the length has they are slightly too short.

The motor idler pulleys on the Z Motor assembly are positioned 33 mm awy from the shaft as per the Voron Docs but are inverted to allow for the larger extrusion. This is a biggy & needs to be noted. Not inverting the pulleys will cause a lot of bother later in the assembly. I will attempt to publish something on this soon.

Please make sure you refer to the Manual addendum pages when published or message me. There are a few tweaks, like reversing the Z axis pulley\idler wheels, that will be bothersome to revise much later in the build.

Additional Tools Required:

Electric hand or bench mounted drill

Threading Tap to thread the extrusion core. Size to suit extrusion style.

Fine metal centre punch.

Bench Vice or clamps makes life a lot easier.

Frame Assembly

There is some basic fabrication required to the extrusions. Some very basic metal working skills are required as a minimum. A bench drill and a vice are not essential but they do make life very much easier. A printed drill jig may be an option if using a hand drill. You will also need either a 6 or 8 mm tap to thread the end of the extrusions. I do not intend to explain the best practise or provide jigs for both these required processes. If the 3030 extrusion includes a linear centre punch detail. marking the centre line 15 mm in with a punch prior to drilling is a relatively easy and accurate operation.

With the blind hole method of assembly, the holes have plenty of tolerance. All they are doing are acting as a clearance holes, allowing access to the wrench to turn the concealed bolt. The bolt moves up and down the linear extruded slot detail so there is plenty of wriggle room relatively.
