Hi, I’m trying to configure my Z axis to work with 2 TMC2209 drivers and 2 motors. I may want to configure it to be able to work individually in the future but now I just want them to work… The tmc2209 stepper z section is in comment because I was having issue with the UART adresses… Here’s my con…

Assuming you’re using driver 4 for z1, you have a typo in your config. The dir_pin should be PD21, not PB21. Klipper3d/klipper/blob/master/config/generic-duet3-mini.cfg # This file contains common pin mappings for the Duet3 Mini 5+. To use # this config, the firmware should be compi…

Oh crap thanks! I did correct it but still get the error with UART if I uncomment the tmc2209 stepper z1 section… With it commented the second Z still doesn’t move. The error : Unable to parse option ‘uart_address’ in section ‘tmc2209 stepper_z1’

By the log I suppose it’s the klippy.log, here it is : ===== Config file ===== [stepper_x] step_pin = PC26 dir_pin = !PB3 enable_pin = !PC28 microsteps = 16 rotation_distance = 40 endstop_pin = ^PC31 position_endstop = 0 position_max = 300 [tmc2209 stepper_x] uart_pin = PA1 tx_pin = PA0 select_pin…

Yes the klippy.log, but attached as a file I can download. What you posted here though indicates you’re board isn’t connecting at all.

[image] OlivierF: mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/ttyACM0: [Errno 2] No such file or directory: '/dev/ttyACM0' This is all that log contains as far as errors.

The file doesn’t seem to update with my last error?!?

I need to see the full log. A parsing error is usually caused by a typo, but I need the log to figure out what is wrong.

I m sorry I cant find your section for [tmc2209 stepper_z1]
without that it won t find the uart for that stepper driver
That might be creating the issue
