Please do not become the first VORON fatality. There is no special Reddit flair for that. Please, read the entire manual before you start assembly. As you begin wrenching, please check our Discord channels for any tips and questions that may halt your progress.
INTRODUCTION STL FILE KEY By this time you should have already downloaded our STL files from the Voron GitHub. You might have noticed that we have used a unique naming convention for the files. This is how to use them.

PRINT GUIDELINES The Voron Team has provided the following print guidelines for you to follow in order to have the best chance at success with your parts. There are often questions about substituting materials or changing printing standards, but we recommend you follow these recommendations as closely as possible.

If you need assistance with your build, we’re here to help. Head on over to our Discord group and post your questions. This is our primary medium to help VORON Users and we have a great community that can help you out if you get stuck.

FINAL THOUGHTS VORON printers are amazing machines that take care and attention to assemble. Take your time! Little issues in the assembly phase tend to stack up and cause you trouble later on. If at any point you get stuck or are just not sure about something, please ask on Discord. There are no stupid questions and we’re more than happy to point you in the right direction.

VORONDESIGN.COM GATHERING EXTRUSIONS GETTING EXTRUSIONS TOGETHER Separate the extrusions you’re going to need for this section of the build. We’ve laid out all the parts you should have and highlighted the ones that will be used in the following sections.
Page 12
VORONDESIGN.COM ASSEMBLE FIRST CORNER M5X16 BHCS Use a low strength thread lock compound here.
Page 13
VORONDESIGN.COM ATTACHING MIRROR SIDE BUILDING SQUARE It’ not a bad idea to build this frame on a glass surface to ensure you can get it as square as possible.
Page 14
VORONDESIGN.COM ASSEMBLE FRAME TOP CHECK THE FRAME Use a framing square and ensure all corners are as square as possible before moving on or you may have problems later on when you start printing.
Page 15
VORONDESIGN.COM BED EXTRUSIONS M5 Shim M5X10 BHCS M5X16 BHCS FASTENERS Insert fasteners before you start. It makes attaching the bed extrusions to the frame easier. Don’t tighten these down too hard at this stage. We’ll want them loose when we install the heated bed assembly!
Page 16
VORONDESIGN.COM Z AXIS LINEAR RAILS M3X8 SHCS CENTERED RAIL INSTALLATION GUIDE When tightening the fasteners to hold the linear rails in place, ensure that you have attached a centered rail installation guide to both the top and bottom. You should have two printed. DON’T OVER TIGHTEN! The M3 fasteners that hold the linear rails to the frame do not need to be hulked down.

Page 24
DECK SANDWICH VORONDESIGN.COM THE SANDWICH The bottom deck panel is held in place by mounting it in between the DIN rails and bed extrusions using M5 fasteners. Depending on the thickness of your panel you may need to use a washer so that the fasteners do not bottom out into the extrusions.
Page 25
VORONDESIGN.COM DECK PANEL & Z DRIVES M5x40 SHCS INSTALL BOTTOM DECK PANEL Flip the frame over and install the deck panel. We’re going to be working inverted for a little bit. You probably want to tape the carriages in place so they don’t fall off the ends of the rails when you flip the machine!

VORONDESIGN.COM Z ENDSTOP PIN 33mm Shaft Deflange GT2 20T Check our help videos in discord if you need help removing the flange for the 20T pulley. Grub Screw...
VORONDESIGN.COM IMPORTANT NOTICE We have specified a notch to be cut into the Z endstop pin along with a grub screw. This is simply to prevent it from falling out if you tilt your machine to do work on it in the future. This does happen (even to the best of us) and can result in a nozzle strike with significant damage to the gantry.

VORONDESIGN.COM Z ENDSTOP PIN Solder Connector It’s possible to solder the JST connector directly to the microswitch if you wish. M3x20 SHCS JST 3 Pin Connector Endstop Microswitch Secure the microswitch with two your M2 self tapping screws. Make sure to remove Microswitch the lever from the microswitch as it will get in the way.

VORONDESIGN.COM BUILD PLATE INSTALL M3x16 SHCS 3 POINT BED MOUNTING M4 Knurled Nut Some people have more luck doing a 3 point bed mount. It can help prevent bed warping.
Page 36
VORONDESIGN.COM Z ENDSTOP INSTALL Z ENDSTOP POSITION The endstop is meant to fit under the build plate, but please make sure that the pin is not touching the bed. It can transfer heat giving inconsistent results in Z probing.

VORONDESIGN.COM LOW VOLTAGE POWER GPIO DIRECT POWER There are some risks to powering a Raspberry Pi directly to the GPIO. While it is very unlikely you would ever have a problem due to the protection circuit in the Meanwell power supply, you may elect to modify a USB cable to take advantage of the built in polyfuse.
VORONDESIGN.COM CONTROLLER WIRING The Voron printer supports multiple controller configurations. Depending on your choice, there will be different wiring requirements to follow. Please check our Discord for specific guides on the controller boards you have chosen.

ENDSTOP WIRING WIRING ENDSTOPS For the purpose of endstops in the Voron - It is safer to wire in the NC configuration as a fault in the endstop or it’s wiring stalls mechanical movement in the machine and produces an error for the user to investigate.
VORONDESIGN.COM PRE-FLIGHT CHECKLIST MAINS WIRING Now is a good time to go back and have a careful look at your mains wiring. Mistakes here can mean bad news so it’s best to get some fresh eyes on things. Verify that your wiring conforms to the previous guide steps. LOW VOLTAGE WIRING Double check that your low voltage wiring has been completed correctly.
