Fucked up and shorted my old BTT Octopus. I have replaced it with the same exact board and I just flashed the board. I'm now in the process of configuring the printer and I just buzzed all of the stepper motors. All of them responded correctly except for stepper_z1 (no noise no movement).
I made sure the wire had no breaks along its length with a multimeter. The motor is still good because I swapped the wires with stepper_z and buzzed it. I assume this means it's a driver issue which I have 2 fresh tmc2209s to put it but when I replaced driver 4 and 5 I still couldn't buzz stepper_z1. Can anyone give me leads on what to do next?

are you satisfied you've got all the motor jumpers on correctly?

I'm pretty sure but I'll double check

Are you 100% certain that it’s the exact same board? Is it possibly an Octopus Pro 1.1? Because that board changed the enable pin for motor 4 compared to previous versions, which would match the failure you describe.

#

This is what the stock config has for Z1, verify that you have the correct enable pin in your configuration:


##  Z1 Stepper - Rear Left
##  Connected to MOTOR_3
[stepper_z1]
step_pin: PG4
dir_pin: PC1
## Octopus 1.0 & 1.1.  Octopus PRO 1.0
#enable_pin: !PA0
## Octopus PRO 1.1
#enable_pin: !PA2
rotation_distance: 40
gear_ratio: 80:16
microsteps: 32
