Notable features for this release:

  • Afterburner Toolhead System, features minimal parts you actually swap, and improved cooling of both hot end and parts. Comes in both Direct Feed and Bowden configurations. We've incorporated all feedback received during the beta testing process and made it much easier to assemble.
  • Direct drive A and B motors allow for smoother belt path and less parasitic loses. Also reduces noise and ringing, while improving machine reliability.
  • Z rails are now centered on the vertical extrusions, allowing use of almost any 2020 T slot profile available.
  • Increased Y travel. There's now a full 10mm of over-travel on Y axis, allowing one to use the Z nozzle probe without sacrificing build plate space.
  • XY joints and Z idlers now use regular 20T toothed pulleys, reducing complexity and cost, while improving reliability of the machine. Z idlers are also simplified and now use single screw for belt tension adjustment.
  • Z drives now accommodate any metal 80T pulley available on the market, including ones with flanges. Metal 80T improve accuracy over printed 80T pulleys, and allow for more consistent gantry leveling results.
  • New front idlers are vastly simplified and also feature single screw belt tension adjustment. This allows users to get more consistent results when tensioning belts and, more importantly, while trying to match the belt tensions of a group of belts.
  • Part counts and variety has been reduced, and printed parts now require much less plastic.
  • Improved bed mounting using globally sourceable spacers in order to help eliminate bed distortion during the build process.
  • Front panel is now a set of doors, using magnetic latches and print-in-place hinges.
  • Screw-down panel clips from V2.1 return with a re-design and improved installation method. They are now almost as quick as the quick-release panel clips to install and remove.
  • Rear fan housing has been redesigned to help utilize more of the filter material. It now uses a 60mm fan for easier 24V sourcing.
  • Rear plug panel sees the return of the integrated non-filtered mains inlet, which is much cheaper and easier to source. It also features dual Keystone terminal slots for easy port extendability (CAT6, USB, etc).
  • Electronics compartment layout has been improved to allow better cooling and easier component management. DIN3 (35mm) rails are the standard configuration now which bring with it much improved installation and maintenance experience. Electronic compartment cooling is now provided by dual 60mm fans, significantly improving component cooling.


  • Take advantage of the Voron on Discord: https://discord.gg/voron. The community is very active on Discord and the users are very helpful on the channel.
  • Download Fusion 360 and get a free license to view the 3D model of the printer. The 3D model is a very useful reference when the manual is ambiguous or unclear.
  • Check out Nero 3DP's Youtube channel, he has a ton of videos on assembling Voron printers.
  • Get a serial number once you finish building your Voron.


  • Spool3D would like to give our thanks to the Voron team for all their hard work creating this 3D printer.

Spool 3D Voron 2.4 kit

I am very happy with the contents of the kit, well packed and complete. I have not assembled it yet though but do not expect any issues at all. I just finished building a Blurolls VORON2.4 3d printer kit and it turned out good. The Spool 3D kit has 1/2 mm thicker panels which I wish the Blurolls kit had. I also like the embedded magnets in the build plate that comes with the Spool 3D kit better than the magnetic sticker Blurolls uses. Including both the STD and HF Dragon options is also a nice touch for Spool 3D. Spool 3D also includes SS hardware which will be nice compared to the carbon steel hardware which may end up rusting over time. Spool 3D also includes an impressive array of tools! That's all that comes to mind right now. I am more than satisfied with my Sppol 3D purchase, it cost me more than the Blurolls kit but well worth it to me! Go for it, you wont regret it. I have never been disappointed with any product from Spool 3D and they are great to deal with as well.

The best 3D printer you can buy

I was going to hold out for the LDO 2.4 kit, but I'm not a very patient person, so I bit the bullet and bought this 2.4 kit. Theres a couple trade offs compared to the LDO version, but I'd say overall they are about par. What you lack in the useful extras in the LDO kit, is made up by slightly better parts. Namely the linear rails and extrusions, while still keeping the high quality LDO motors. I'd recomend that you print off the klicky probe as soon as you get this built. The probe that came in this kit (The same one in the Voron BOM, so no fault of the kit) melted on me in the first few days. The klicky probe mod makes the printer much better however, so no big deal, just make sure you have a spare endstop to use for it. The only part not included with my kit was a bed thermistor, which I believe was just an oversight and might be fixed in later kits? Luckily I had a few spare. The wires included in the kit weren't long enough, I had to splice probably 10 inches or so to the end of the hotend harness for it to reach my controllers. It probably would have been plenty for a 300 kit, but not the 350 kit. I also had to do a bunch of troubleshooting to why my probe was getting inaccurate readings. It turns out its because of the bed design. The included print bed has slots bored out of it, and rare earth magnets fitted in rather than the magnetic sheet glued down to it. This screwed with the readings of the probe and gave me skewed readings. This doesn't effect the klicky probe mod, so I really recomend that ASAP. This design of bed is honestly better IMO, just really shows that Voron needs to adopt a different probe design. The heated mat thing for the bed isn't pre-installed like the LDO kits, and will fall off if you don't pick up some RTV sealant for the edges. The adhesive will burn off and smell your house up if you don't. If spool3d wants to earn some brownie points, maybe they can pre-seal these beds down since it takes over 24h to cure and their customers will be wanting to get it built asap ;) This kit also includes roll in style T-nuts. I was going crazy undoing my frame several times sliding them in as the instructions don't mention pre-loading these nuts like the v0.1 kit does. Turns out theres a way to install these without sliding them all the way from one end. Check the discords pin's in the 2.4 channel. (You kinda force them in on an angle, the ball bearing springs inward). If I could make some recomendations for this kit, it'd be to add about a foot of wire for each part of the hotend, pre-glue the bed down with RTV and include 2x M3x50mm bolts for the stealth burner, because those screws were hard to find. Maybe also add an upgrade option to upsell the 36mm pancake stepper needed for the stealth burner too. Overall, an excellent kit. I've owned probably 10 different printers including the V0.1 and this machine is incredable. You'll have a hard time finding anything this quality under $8k (or probably way more). You're only limited by your own skill of building. This is not a beginner project, but theres lots of help on the Voron Discord channel if you need it.
