  • Page 3 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.

  • Page 4: Introduction

    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.
  • Page 5 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.
  • Page 6 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.
  • Page 7 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.

  • 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 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 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.
