Voron 2.4 Build, Mods and Tweaks

Voron 2.4



This was my build list for the 300mm Voron 2.4 I built. I am planning on updating it to 2.4R2 and will list those components as I find them.

I ordered parts from Amazon, West3D, DigMach, KB-3D, Fabreeko, Printed Solid and Mandala Rose Works.

More recently I have seen parts and even kits appearing on Amazon. A lot of the parts are the same manufacturers as those from other suppliers, but with Amazon Prime shipping and potentially cheaper prices. I had a lot of issues with components I originally sourced from West3D and DigiMach. They were both good at helping me fix the issues, but it took a long time to sort out which was not ideal. I also hit shipping issues with other suppliers that has pushed me to looking more at Amazon now than I did previously.

Afterburner PCB

I decided on Hartk1213's "Voron Afterburner Toolhead Board v3.rabbit (also known as ERCF PCB board)" since one day I may add a ERCF Filament changer.

You will also need a new PCB cover from here

Since the PCB has a temperature sensor built in, I ended up using this cover with air vents

2. Bed Wagos

I strongly recommend using Wago 221 wire connectors between the bed wires and the board underneath. This makes it a lot easier to remove the bed whenever necessary.

I bought this Wago kit so that I would have plenty on hand, I now use them all over the place.


Bed Wagos

Use the bed Wago mount to make the bed wiring pluggable:

3. Nevermore Micro

Instead of the extractor filter and fan I am installing the Nevermore Micro V5 Duo mod.

4. Filament Latches for panels


5. StealthBurner upgrade

Updated the tool head to the Voron StealthBurner.

Parts kit: Amazon

I pulled the trigger a little early though so I have a pre-release build that I will need to reprint now that the final release is done.

6. Klicky Probe

This has been the best mod so far. This mod replaces the original inductive probe with a contact switch. The best part is that, combined with some klipper macros, we can use this mod to do auto z-offset calibration, no matter which build plate you use.

More info here

7. Decontaminator Nozzle Brush

This is a great mod that gives you a nozzle scrubber and purge bucket for cleaning your nozzle before each print. Couple this with the purge and clean macros in my config to ensure a clean nozzle every print.


Upcoming Mods

Here is the list of mods I plan to assess and probably implement:
