Unable to read tmc uart 'stepper_z3' register IFCNT

Hey everyone!

I'm working on my first build for a Voron 2.4 and I cant seem to get past this error:

Unable to read tmc uart 'stepper_z3' register IFCNT.

I'm using the BTT Manta M8P V2 as the controller with the CB1, and have the BTT EBB SB2209 also installed and connected through CANBUS. I have flashed the firmware for both Klipper and Katapult to both the toolhead and the M8P, both took successfully and the MCU connection is able to be made, as well as the MCU EBB. I'm getting data back with extruder temps temps from the tooldhead through the CAN network. I have tested the power output and 24v is being pushed out, so I know there is power to them (I have checked and confirmed with my multimeter)

I have checked my wiring, all looks to be correct. Jumpers are in the correct location. Every time I try and home the print head, or move it in any direction the above error is thrown and I am at a loss as to what it could be.

Does anyone know what this may be cause by? I cant find the issue and I've searched high and low through multiple forums, discord groups and reddit. I've attached my printer.cfg file, klipper log and images of my wiring and jumper locations

so the config says

## Z3 Stepper - Front Right on Motor7

now...look at your photos....do you have a driver in slot 7?

You have got to be freaking kidding me.

I need to drink more. Almost 6 hours and it was staring me in the face the whole time. Thanks for letting me know. I do appreciate it.

I’m going to go re evaluate my life choices now
