HI im new to vorons printers and looking to buy a formbot 2.4r2 kit.

i am a bit confused on if i really need all the parts i found on github or which one to leave.

Since i am not too far into the different boards and mods one can do, i don´t know what i really need. Also what parts are just decoration and what are functional.

Also are all parts i find on Github actually compatibale with the can system and btt board the formbot kit comes? There is a few files on Formbot which i guess i need all of.

It feels like there are way more parts listed then what i can buy of from the formbot site.

Im am a bit overwhelmed

Anyone who can help me figure this out?

This is a tricky one, it's almost easier to say what NOT to print. Anyhow.
Something to remember, once you get to the electronics; The Formbot kit has the whole electronics compartment ROTATED BY 90°, check their wiring guide. Some cables will not be long enough to reach where they need to if you go strictly by the official Voron manual. This could depend on the size of printer purchased, but my 350 had to be built according to Formbots wiring picture. https://drive.google.com/file/d/19wdkwaP-MP6JrulkZ-r0Kav1kbvxzPzk/view

You'll want to click on "STLs" on this website to get the complete package of files. https://vorondesign.com/voron2.4
It's fairly tough to keep track of this, to be fair. Starting with the files from Formbot, you'll need everything in there except 3-6.stl, they ship that unit already mounted in a printed part.

The kit comes with Voron TAP. So you need to print the files here too: https://github.com/VoronDesign/Voron-Tap/tree/main/STLs The manual for TAP specifies what to print, all the files and then only one of the sensor mounts.

You'll really want to print most things, except;
Superceded_parts, skip.
Bowden, skip.
Test_Prints, skip.
Skip any parts that deal with the stock, small front display, (mini12864) you'll be using the BTT HDMI 5" from the kit and those are in the Formbot files.
You only need the correct bracket for your BTT Manta, none of the other ones in the package. Manta is a brand new upgrade for the Formbot kit, so the Octopus bracket may or may not fit, check the hole dimensions before printing.
You'll use Voron TAP for Z-offset, homing, quad gantry level, making a bed mesh and so on. So none of the probe mounts, brackets or retainers are needed.
The kit has generic cable chains, only chain anchors for 3 hole chains is needed.
Only the printhead that fits your specific hotend is needed, none of the others.
An ADXL345 can be mounted directly to the hotend assembly, this is mentioned in the manual, so you can skip the ADXL345 files.
The PSU only needs the "lrs_200" psu bracket, the PSU_stabilizer will not fit if the electronics are turned 90 degrees.
RS25_psu bracket is not used. Wago mounts are not used.
Anything to do with "hall effect" for endstops is not used, skip those files. You have physical limit switches for X and Y.
Skip the whole "X_carriage" folder since the Voron TAP files replace everything in there.
Skirts are all optional, but I recommend them, to keep fingers out of the electronics compartment but they also add that much needed PIZZAZZ 😛 Oh and some of the skirts hold the cooling fans for the electronics, just print them all!
The skirt that holds the filtered power inlet is not optional however. Skip the other types of power inlets.
Skip any skirt folders that aren't for your model, obviously.
Nozzle probe, skip.
There are two doors for the print head, one has "pcb" in the name, pick that one.

Hopefully people can correct any mistakes I've made here.

Id recommend reading the manual too before going into all this. It'll give you a better idea of what goes where, what you probably should and should not print etc. But yes it is a bit overwhelming at first, but eventually it clicks.

yeah im already on it. im not that scared about all the mechanical stuff and extrusions etc. but the wiring and not having it go up in flames is what gets me
