Hello all,
I have an issue where I cannot set the details for the tmc2208 driver in the extruder section.
All the stepper drivers are the same & all have all been soldered on the back to enable me to use the uart.
In the section [stepper_extruder] I get ar error for the step_pin, dir_pin, enable_pin & rotation distance.
However, if I comment out rotation_distance it tells me it is needed.
I can run the extruder in standalone mode.

I have attached the config file & the klippy log.
Many thanks in advance to anyone who can assist.

Hi @Gruntfuttock ,
[stepper_extruder]
isn’t a valid configuration section. I think you’re looking for [extruder]
. To set TMC parameters, you use [tmc2208 extruder]
. Example with your config:
[tmc2208 extruder]
uart_pin = PD9
run_current = 0.8
stealthchop_threshold = 999999
[extruder]
microsteps = 16
rotation_distance = 40
nozzle_diameter = 0.400
filament_diameter = 1.750
heater_pin = PE5
sensor_type = ATC Semitec 104GT-2
sensor_pin = PC1
control = pid
pid_kp = 14.669
pid_ki = 0.572
pid_kd = 94.068
min_temp = 0
max_temp = 250
In your log, there’s also a connection error:
mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-Klipper_stm32f407xx_240039000551333438353530-if00: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-Klipper_stm32f407xx_240039000551333438353530-if00'
What’s the output of the following in SSH?
ls /dev/serial/by-id/*
Thanks for looking at this.
I’ll amend the extruder config tomorrow. If it works I’ll take it on the chin as either muppetry or a senior moment.
No sure about the connection issue, it connects every time I switch it on. I will have a look just in case.
Yes that worked.
Thankyou.
I now have another issue, the oart cooling fan does not self start. I can start it manually from Mainsail.
I get unknown command M106.
Any ideas?
Please attach a recent klippy.log to your next post.
Thanks for the reply, I haven’t been back to the printer for a while.
The issue is the part cooling fan does not auto start. I can manually start it.
Many thanks
Tim
