Formbot Voron 2.4 build log - In pursuit of multiple toolheads

[honest prairie]

My Formbot kit arrived today, thanks to the current USD exchange rate at a very reasonable price.
I create this build log for myself, but also to have more information about the printer available in case I have questions or problems (very likely).

It's my first Voron and I don't really need a printer of this caliber. It's more of a project that I can tinker with when I have some spare time, but you never know what you'll come up with when you suddenly have the possibility to print almost any material. ;) Also, my faithful Ender gets something to do again, because he is now printing all the ABS parts.

The current goals are as follows:

• Have fun while building
• Hopefully a working printer in "standard" configuration
• Extend to 4 toolheads with Stealthchanger

If you see something that I can do better, please let me know. I'm relatively new to the Voron community and will probably have to read up on a lot of things as the build progresses.
See you later! ^-^

The frame is finished and square!
Really nice extrusions in the Formbot kit, the diagonals match within less than a mm without much effort.

The linear rails are cleaned and greased, ready for installation.

[frank ingot]

Welcome! I like how organized you are. My workspace has never looked like that.😅

[honest prairie]

Thank you very much! :)
I always try to have only the necessary parts on the work surface. Reduces the risk of mixing things up or forgetting steps.
Of course, it's all lined up extra pretty for the photo. 😉

[frank ingot]

Yeah that linear rail photo is

You mentioned an interest in multiple toolheads, and that is something I'm interested in as well, specifically for printing with soluble (BVOH or PVA) support material for projects with moving interior parts. Is that your interest, or is it something else?

[honest prairie]

I would like to print with multiple materials, but probably nothing water soluble. 😉
More likely PETG with PLA support or vice versa.

Z Rails and the deck panel are installed:

Today I built a Nevermore Micro V6 for later installation.

[honest prairie]

Alright, the Z Drives are done! I'm having a blast so far. :D
Everything in the design is so well thought through.

[pure sail]

It's highly addictive 😄

All of a sudden you find yourself having the full voron lineup of printers, hehe

[honest prairie]

After a few days break I was able to make some more progress today:

• The Z idlers are installed
• The Nevermore filter and bed are installed
• The A and B drives and idlers are assembled
  I chose to cut the provided wires for the Y-stop on the A-drive mount and installed a connector instead.

[honest prairie]

The Gantry and Belts are in! 🥳

[honest prairie]

Tap is done, the Stealthburner is next.

[honest prairie]

Ok the ammount of work to assemble this Toolhead is kind of ridiculous. Looks good though! 😆

[honest prairie]

It's been a while... but I wasn't completely inactive. Most of the wiring is finished! I didn't take many photos, first of all because it's not particularly interesting, and also because I'd better concentrate. Lo and behold, all the magic smoke is still inside ;D
The result:

[honest prairie]

No pictures today but it's moving! 🎉
All fans and heaters are behaving as expected. Also tap / quad gantry level is working.
Now it's starting to feel like a 3D printer. 😄

[honest prairie]

I've done a lot of tuning in the last few days. So far the side panels have only been held together with tape and prayers. xD
But yesterday the results were finally good enough to print the clips. I also printed a silicone nozzle wiper, but it's not installed yet.

[honest prairie]

Wow, this build log has become a bit sparse lately... To be honest, I didn't have much time besides work and just wanted to finally get the kit done.
Here it is: my “stock” Voron 2.4. It works beautifully and looks great on my new 3D printer table. 😄

I hope to document the upcoming modifications in more detail again. Planned so far are:

• Fridge Door Mod
• Camera
• StealthChanger with 3 Dragon Burners (expandable up to 5, a self-made exhaust PCB is already on its way)
• Filament box on the printer

Cool build log with really good pics, hope it serves you well! 🙂

[honest prairie]

Thank you! 😁 I'm sure it will.

[honest prairie]

The exhaust PCBs arrived!
However, I already discovered the first mistake: The input connector cannot handle the current I need for multiple toolheads. 😅 It's already fixed for the next revision but for now I will just solder the input wires.

This is the backside, it connects all the toolheads in parallel to power and in series to the CAN bus with a termination resistor at the end.

Looks cool

[honest prairie]

Thanks, I'll put it on GitHub once I'm sure everything works. 😄

[agile hound]

Sounds great! I would like to turn my v2 into a stealth changer sometime. What kind of mods are you using?

[honest prairie]

I'm still in the planning phase (and procuring material), but I'll upgrade to Mini BFIs, install a crossbar with Modular Docks and then build 3 Dragon Burners with the PCB I made.

The parts for the fridge door mod are also already ordered, but that has nothing to do with the rest. 😉

[honest prairie]

I've just prepared the umbilicals, I think I have to add some more strain relief to the connectors on the exhaust side. The heat shrink tubing is not enough to prevent buckling.

The D-Sub connector allows me to disconnect all cables going to the upper part of the printer (CAN, power, lighting, exhaust fan) in case I need to remove the rear panel.

Hi, do you have any small tools to print for the assembly? Example to adjust the position of the pulleys on the engines or even a guide to avoid losing the balls of the rails?

I have exactly the same project as you. I just received my formbot kit. afterwards I will install a multi-tool for it.
