do you have the wiring correct , the pins face up on the display.
while I dont have this yet but I have read a lot about this and it always narrowed down to the cable connected in a wrong way.
have you not assembled your toolhead extruder hotend combo based on BTT EBB 36 for the electronics , does it not need the U2C Can adapter or did you directly hook it using USB plugged into your pi ?ahhh U2C can be removed as is still unused

did you convert your octopus pro into a can device and connect to ebb36 using CAN ?EBB36 is connected directly to octopus pro, and works perfect
Also looks like you got your btt tft70 working , how did you fix that.

You can flash Octopus with enabled CAN instand of USB - you choose it when you set settingo for build klipper. And after that, octopus works like u2c, and you not need u2c any longer.
About TFT70 - screen works, touch still not. I have to work longer on it.

i was reading about why people prefer to use a dedicated u2c board like the btt u2c adapter for interfacing with the can extruder board like btt ebb36 and it was called "timer too close" just google it.
this video comments section mentions about this issue.
now that this works and talks via CAN how can I flash klipper to it is it via some can communication with raspberry pi ?
this part is a bit hazy to me. is it via some python code I dont recall this but I rad something around it ?

RPi still use USB to communicate with octopus, CAN is used to communicate between EBB36 and Octopus Will try to write more tomorrow if you want. FOr now all works fine.

when you have some spare time at hand do write about itRPi still use USB to communicate with octopus, CAN is used to communicate between EBB36 and Octopus
- how the communication happens between these devices
- how would you flash klipper to octopus when its on CAN
- also would like to know if you do encounter timer to close errors

How it's copnnected: 
So EBB36 to Octopus Pro via CAN, RPi to Octopus via USB
Flashing works via USB. You have to set configuration in `make menuconfig` like this:
And works perfect. None of `timer to close errors`

Sorry, I have no time recenly. So, here is PTFE connected to CAN, and this tinny string is something like this https://www.amazon.com/KEY-BAK-RETR...key-bak+retraktor+mini-bak+id,aps,214&sr=8-11 with this https://mods.vorondesign.com/detail/avSsiCFH7Vte3kYhqt4atA .
White parts are from eSun ABS+ cold white.

did you use esun abs+ for your voron parts. did you see any layer adhesion issues with esun abs+ prints ?

Yes, I have all parts from eSun ABS+, and no problems with layer adhesion. Soon I will start build v0.2, and I will use Fiberlogy ABS, becouse I want to try them onyx colour.
