Spider v3 cant run BTT EBB 2209 CAN toolhead (Fysetc Voron 2.4 R2)

[inkvi601]

Id like to ask you, if there is any compatibility problem to use BTT EBB 2209 CAN toolhead with Spider V3 controller?

I flashed firmware on both (Spider3 and EBB CAN module), controller is normally running using CAN bus, but when I try to turn on the EBB CAN toolhead module, entire electronics is silent - there is only one red LED flashing (24V label red LED on Spider).

I dont understand, where can be a problem, since the toolhead module is using same voltage. Everything is working with original Fysetc CAN toolhead module... Im using original FYSETC CAN cable provided with the kit.

I found the issue. You have error in your drawing.

Your original wiring image from Fysetc wiki: https://wiki.fysetc.com/assets/SB_CAN_ToolHead_V13_Wiring.png

You have +24V (red cabel) on the bottom pin fo CAN cable connector. But in reality, you have it on the top pin (you have it right on Voron wiring image). So you have it swapped- drawing from wiki vs. reality.
