Voron Trident Can Bus EBB36 upgrade

Note: the printhead LED's connector is reversed.

also reversed is extruder motor (fixed in config).

There was a sticker on the TMC2209 that prevents heat sink to stick.

Recommended order of assembly:

Remove cable chains.  Install both X and Y endstops.

best STL that I found:

https://www.printables.com/model/429169-rigid-ebb36-v12-mount-on-voron-cw2-stealthburner-t

Using BTT u2c 2.1

BTT EBB36 v1.2

https://github.com/EricZimmerman/VoronTools/blob/main/EBB_CAN.md

The End stops must be moved, also need mounts for umbilical:

The X-endstop uses existing mounts on the carriage.

Can Bus Cable

I used silicone wire (red/black) 18g and 22g and 1/4 inch nylon sleeve.

You have to widen the end of the sleeve by cutting it off, putting it on
a x-acto knife and re-melting.

It needs a stiffener 3mm nylon or PTFE

I think the opposite twist was good, making the sleeve a bit easier. 
The stiffener (either ptfe or nylon) was critical.

It was somewhat difficult in spite of seeing it done at work so many
times...

Very important to verify that the connectors fit well.

Setup canbus on voron:  (i used 500000, and i think by doing it in this order, it propagates).

https://github.com/rlaferla/Voron/blob/main/CAN_Bus_Guide.md

Setup u2c, follow instructions from:

https://github.com/bigtreetech/U2C/issues/4

setup ebb36 

Follow instructions from:

https://github.com/Arksine/katapult

and 

https://github.com/bigtreetech/EBB  (klipper build settings)

Wiring:

24v probe is problematic.

VERY IMPORTANT, don't forget to remove the USB jumper on the ebb36.  Also, if your canbus cable power works, the power LED lights up on ebb36.
