Dual Z TMC2209 Issue

OlivierF · July 26, 2022, 12:13am

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 config :
Duet 3 Mini 5+

[stepper_z]
#driver2
step_pin: PC24
dir_pin: PB28
enable_pin: !PC28
microsteps: 16
rotation_distance: 8
#endstop_pin: PC5
#position_endstop: 0
position_max: 400
#Uncomment if you have a BL-Touch:
position_min: -4
endstop_pin: probe:z_virtual_endstop
#and comment the follwing lines:
[stepper_z1]
#driver4
step_pin: PC16
dir_pin: PB21
enable_pin: !PC28
microsteps: 16
rotation_distance: 8
#endstop_pin: PC5
#position_endstop: 0
#position_max: 400
#Uncomment if you have a BL-Touch:
#position_min: -4
#endstop_pin: probe:z_virtual_endstop
#and comment the follwing lines:


[tmc2209 stepper_z]
uart_pin: PA1
tx_pin: PA0
select_pins: PD0
uart_address: 2
run_current: 1
sense_resistor: 0.056

#[tmc2209 stepper_z1]
#uart_pin: PA1
#tx_pin: PA0
#select_pins: PD0
#uart_address: !0
#run_current: 1
#sense_resistor: 0.056

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 compiled for the ATSAMD51P20
# with a "25Mhz crystal", "16KiB bootloader", and USB communication.

# To flash the board, double tap the board's reset button to enter the
# bootloader and then run: make flash FLASH_DEVICE=/dev/ttyACM0

# See docs/Config_Reference.md for a description of parameters.


# Pins for reference:
# Driver Step Pins - 0:PC26, 1:PC25, 2:PC24, 3:PC19, 4:PC16, 5:PC30, 6:PC18
# Driver Dir pins - 0:PB3, 1:PB29, 2:PB28, 3:PD20, 4:PD21, 5:PB0, 6:PA27
# Driver Enable - !PC28
# Uart addresses - 0:0 1:1 2:2 3:3 4:!0 5:!1 6:!2 | "!" is for inverted select pin
# Thermistor Pins - T0:PC0, T1:PC1, T2:PC2
# Vssa Sense:PB4 | Vref Sense:PB5
# Current Sense resistor for drivers - .076ohm
# SPI lines:{PD11, PC7} -> Shared SerCom#7, SPIMosi:PC12, SPIMiso:PC15, SPISCLK:PC13
# Vin Monitor:PC3, uses 11:1 voltage divider

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’

Post a log with the error.

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.

jakep_82 · July 26, 2022, 1:28am

This is all that log contains as far as errors.

OlivierF · July 26, 2022, 1:35am

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

OlivierF · July 26, 2022, 2:01am

jakep_82 · July 26, 2022, 2:12am

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.

tigs · July 30, 2022, 12:20am

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
