FT EMS V2.4 350 V2

FT EMS V2.4 350

Welcome to FizzysTech Electronics Management System designed for the Voron V2.4 350mm build.

INTRODUCTION

Not a fan of DIN rails and VHB tape - Sorry VoronDesign team. So I have designed my own printable modification to properly mount and manage the cabling required to build a Voron 2.4 350mm printer. This is version 2 of the frame after that has been tested by the community. 

THE DESIGN

This design was extended from the V0.2 and Switchwire Electronics Management solutions I previously created. It is designed to remove the need for DIN rails and especially VHB tape (Yes VHB tape has its uses but NOT for mounting electronics!). The components are designed and mounted on hex stand-offs and can be moved to wherever your heart desires. My initial implementation is intended as an example but it really is up to the end user to place the parts where they want them to be located and print only what is needed.

BOM

1. 16 x M5x10 BHCS
2. 4 x M5x16 BHCS
3. 8 x M3 Threaded Inserts
4. 8 x M3x6 BHCS

INSTALLATION INSTRUCTIONS

EMS is designed to be extremely flexible as to let the user decide what hardware to use on the printer. Therefore we have created a mounts repository where power supply, controller board, expansion board and single board computers (Raspberry Pi) mounts are stored. Please visit our mounts repository to download universal cable ducts and mounts for the hardware you intend to install - https://www.printables.com/model/558357-ft-ems-mounts-repository

Which hex mounts do I need? Here is a breakdown of what each are used for: -

1. Mount A = hole directly in the center of the hex and the screw is inserted from the mount side
2. Mount B = hole is with a 5mm offset and the screw is inserted from the mount side. Depending on which direction you need the offset you can rotate the hex so its actually 5mm offset in 6 directions!
3. Mount C = Cable tie in the center of the hex in the vertical orientation
4. Mount D = Cable tie in the center of the hex in the horizontal orientation
5. Mount E = These are used for electronic mounts that have a heat insert in them. The screw will go through the center of the hex from behind into the mount. These are typically used for SSR and some PSU mounts.
6. Mount F = These are used for electronic mounts that have a heat insert in them. The screw will go through the center of the hex from behind into the mount. These are typically used for SSR and some PSU mounts.
7. EMS Bolt = this is used for awkward mounts and load into the channel on the electronics mount with an M3 heat thread insert preloaded. These work in combination of Mount E and F.

We recommend printing the whole set of parts and test fit them outside of the printer prior to installation. This will serve as a double check to ensure that all the correct parts are printed and prepared.

1. Remove the printed supports from each of the 4 frames.
2. Prepare all of the parts and insert the heat-sets where needed. 
3. Assemble the entire EMS frame along with the electronic components outside of the frame prior to installation 
4. Use the correct mount and the hex (Mount A) or if you require a 5mm offset then use hex (Mount B) 
5. An optional EMS Bone Bracket can be used to join the 4 frame pieces together. These are downloadable from the EMS Repository linked above.

Hope that you appreciate the amount of time and effort to turn around such a big modification. If you like my designs and would like to contribute to fund filaments and other equipment required for prototyping, please do so at my paypal.me or Ko-fi. Your support is greatly appreciated :) 

Do let me know what other boards you intend to mount.
