Very interesting project and concept! And questions...

[bsafh]

That's really nice!

Minor questions:

• could it be possible to use the BTT EBB42 gen2 (instead of gen 1) to be future proof and to switch from cursed Molex ports to the standard xt30 ports on the the new EBB Version? That way all can cables could be xt30 plug'n'play without crimping! That would need some new printed parts and change the wiring a bit

• or could it benefit from using a Fysetc Hexa Fusion distribution board (xh2.54 for CAN-H/-L) (max 6x CAN with own STM chip, canbwork as CAN-BRIDGE)

• or could the useage of BTT CEB (6 boards) or Mellow CANbus Expand (4 boards) simplify wiring?

You can use a EBB42 gen2, but there are no benefits over using the older ones (besides no molex) and they cost alot more. Generally speaking you can probably use pretty much any board(s) as long as you have these ports per lane:

• Stepper Motor & driver
• I2C (for humidity sensors)
• Endstop
• RGB

Additionally you need either one of these once:

• Probe (Sync Feedback sensor)
• Thermistor (PSF sensor)

However keep in mind that there will probably some changes necessary, for both printed parts and software configuration. There is a dedicated board in development, which should be release soon(ish).

A dedicatwd board would be good, hopefully CANBUS...

Are there any plans for Kits to be sold?

[fronti90]

AFAIK that board would use CANBUS and kits are in planning. You should joins us on discord, plenty of information there! :)

Both boards and kits are in development and should be out soon :) EDIT: They are all out! https://github.com/DW-Tas/EMU/blob/main/docs/sourcing.md

EBB Gen 1 boards are cheap hence are a good fit. Gen 2 while easier to wire, is triple the cost right now, which materially affects the per lane cost for no good benefit other than one off ease of connectivity :)
