Configuring a belt printer

General Discussion
1

Basic Information:

Printer Model: Ender 3 (if you can call it that at this point)
MCU / Printerboard: creality 4.2.2 + btt octopus
Host / SBC: orangepi 3b
klippy.log (not pertent, asking about configuration)

Describe your issue:

I have avitiva3d’s ender belt kit on my ender 3, however their docs don’t go over Klipper configuration at all. The belt for the kit is used as the Y axis, i.e. like the cr30 but at 90°. How would I go about configuring the y steppers. I plan on having 2 steppers for y on different step sticks

There was a prelim config here but it had some issues.

I made a comment with the few things I saw, but should get you at least started.

E3 4.2.7 board

Didn’t see your config and I’m new so maybe I missed it.
Above is the klipper configuration for a creality 4.2.7 board.
Your secondary board seems a bit, not needed but I don’t know what all you have planned.

My belt is z and I have basically a normal x, y Cartesian on my e3 belt.

There’s 4 extruders and there wasn’t enough stepper ports to drive 4 extruders when using 2 y motors on different ones
