3D Printing Canada - Voron 2.4 BOM

I have had a couple of requests for the Voron 2.4 BOM of the kit we sell. Below I have a detailed list displayed.

You will have to build your own wiring harness but all supplies are included.

3D Printed Parts not included (but for sale as an addon with the kit)

Hey Jason,

I’m in the process of getting the parts together for a Voron 2.4 r2.

Can I say that the list you’ve posted here needs scrubbing? You’re listing the “BTT Octopus V2.1” and a “Controller with 7+ Stepper outputs” which are the same thing. I’m not sure why you’ve listed a “Raspberry Pi orange P1 mini” when everything I’m seeing is the Raspberry Pi 4. The “Hotend Kit” is something that isn’t as definite as it should be, which is listed as part of the problems below.

We’re still in the Covid parts shortages and you’re going to have problems especially with the electronics Raspberry PIs (of all models) are getting very hard to find. You can still get a few RPi 4s from companies on AliExpress but their prices are going up continuously. I can’t find anybody in North America that has them. The “genuine” Omron inductive sensor is basically not available anywhere - from what I’m seeing, most people building Voron 2.4s are looking at using Klicky as the height sensor.

Despite all this, it’s not the BoM you’ve listed above that’s been the biggest problem for me, it’s getting an accurate list of the parts that are to be printed (and understanding what are the different options for the drag chain mounts, the mains panel, etc.).

I was trying to keep everything organized, but the instructions/configurators don’t provide a concise list of the 3D printed parts and I’ve tried going through the pages to make sure I have everything ready for putting it together when I have the mechanical parts together. So far I’m up to page 241 of the assembly manual in terms of getting the parts together:

I’m excited about building the printer but it’s definitely not for the faint-hearted. As has been noted, the assembly manual looks outstanding but has a lot of holes and is incomplete in a lot of areas (including explaining different options).

Oh, and the suggestion that you’ll need 1.6kg of Black and 0.5kg of your accent colour is maybe half of what you’ll need - you’ll need to do some experimentation to ensure that the prints come out flat as some of them are pretty big and PLA is recommended for all of them. That’s why you see rafts in the prints above.

Once I get everything together and start putting together the printer, I’ll let everybody know how it goes. I’m expecting assembly and set up to take probably about a month (40 hours of actual work).

HI Myke

Thanks for picking up on that, I will scrub it a bit more,

This list is actually the list that is in our Voron Kits, Not a list to build one (although they are very similar) Our supplier is including everything listed on here including the Orange. You are correct its not the full Pi4 but we have it running here in the store and does work quite well. Little different setup from the PI4 but does function.

We had a couple of people ask for our BOM so I downloaded the VORON BOM for the 2.4 and tried to make a list of what is in our kit.

Printing is the biggest commitment. they are available as an add-on when you purchase the Voron Kit. I went a slightly different tact with my voron, I used the CNC machined parts instead of using printed.

You are correct time-wise, It is about a 40-60 Hour build time assuming everything is ready to go on the low end and if you still have to cut extrusion or rails you are on the high end.

Hey Jason,

Question for you - does your kit include the Hot Insert Nuts? I think it’s the “M3 Threaded Insert” (with 110 quantity, which seems about right) but I wasn’t sure.

Interesting about the RPi Orange - I haven’t seen anything about them in my research other than people using other versions had poorer quality prints because they don’t properly process double precision float values as well as the Raspberry Pi 4.

Now, just looking around, I found:

One other thing I forgot to mention in my original reply that it seems that all the cool kids are going with the Afterburner toolhead PCBs as it cuts down on the amount of work making up the wires for the hot end:

A bit pricey, but I’m looking forward to using it with mine. According to AliExpress, the two I ordered are in the country.

Right now I’m waiting for a date for the machined aluminum plate and trying to find a thermal fuse before starting to build. I have basically everything else with two or three items a day away from being received (with still a few 3D printed parts at the bottom to do as well as find a Mean Well 5V AC/DC supply but that’s not a show stopper - I may have a bulk power supply lying around somewhere here that I can use).

I keep seeing/reading how amazing the printer is and I’m looking forward to getting mine together.

Hi Myke

yes our kit it the afterburner setup with the dragon hot end.

The orange is as close as you can get to the 4 without actually being there. I know the image setup is different but it does work. I have a couple of Pi4s at my place so I stuck one in mine.

There are actually a couple of PCB options for the afterburner. Yes most common is the toolhead board which is nice however I went with the next step, I am using the Duet 3 mainboard with CANbus and am setting mine up with CANBUS. The Hovard to be specific, HUVUD Toolboard – Lukes Laboratory

I got 2x of the V.60 version and added the resistor because it has the shaping accelerometer built into it. Only going to be 4 wires going to the tool head and I am going to set it up on the umbilical setup so less moving mass.

Good to know about the RPi Orange - I have three RPi 4s, so I’m good.

I know I commented somewhere on the HUVUD Toolboard and I said I wasn’t wild about the connector placement; I didn’t think it was that well done in terms of keeping the wires simple at the hot end. I also want to understand the timing delay for the STEP pulses to the TMC2209 and nobody could give me a good explanation of what they are.

The concept is great and I like the idea of the hot end temperatures/fans being controlled by a remote processor. I’m just not 100% sold that there won’t be stepper timing delays through the communications hardware/software. This is also true for end stops.

I like the idea of just four wires (two 18 gauge stranded for 24V/Gnd and a couple 28 or 30 gauge for the the signals) but I want to ensure that everything works at the appropriate speeds with no delays from the rest of the system.

absolutely, I agree, that’s why I am taking the genie pig on this one and testing. I do have the Voron Toolhead board as well for a backup but gonna try the CANBUS first.

The kit I have is one that was tested from a supplier we did not end up going with and chose the one we currently have in stock. There were a few issues with it not to mention the price was high but just means I get to build one.


Just an update - for Future Voron Kits - the OrangePi is NO LONGER INCLUDED as part of the kit.
