prusa mini- klipper error
Hi everybody... I have a issue with klipper.... I would like to use my prusa mini with ratos... motherboard flashed... all done without any problem but I have a klipper error in main sail
I check the printer config file and ratos.cfg but didn't find the problem
Did somebody have this issue?

Going through the config files now, have you already run through the configurator without issues?
yes
no issue in configurator
line 65:
4p_toolhead_cooling_tach_pin=PE14,
line 265: pin: PE14
line 267: tachometer_pin: ^PE14
did you make any edits to RatOS.cfg after running the configurator?nothing
Have you updated ratos-configurator?
yes all is up-to-date
Hm. The Prusa Mini is not officially supported, maybe @miklschmidt could point us to who created the pinout/configs for this and we could ask them. In the meantime try running through the configurator again?
ok i'm trying right now
still same error
Are you choosing 4-pin fans, or are those coming automatically?
coming automatically ... if you choose another option you have a error in the end of configurator
What is that error, out of curiosity?
okay, run the configurator back the way you had it, and try editing line 265 to
pin: PE9
I don't know enough about how the configurator works to figure out why these are explicit pins instead of their aliases as written in lines 62-67, but looking at boards/prusa-budd/config.cfg, that should get you up and running for nowline 265 in RatOs.cfg?
Another error after modify
okay, open printer.cfg and change line 60 from
[fan part_cooling_fan] to just [fan]
hm, that might not do it. Lemme see what my printer.cfg looks like (if my dang printer will get on the network)After the change I have this now
Give it a few minutes, I think that means it will at least start now
I have another problem...
every time I boot the pi , the RatOs modifications are away... the pe9 go back to pe14
error mcu now
okay. We should have done this the right way in the first place, that is my mistake. In printer.cfg somewhere like line 128, add:
done
Your raspi is connected to the buddy, correct?
yes
Are you able to ssh into your pi?
I'm connected
run
lsusbI
pi@RatOS:~ $ lsusb

pi@RatOS:~ $
Okay, unplug the buddy and run it again. I think that second line will disappear
yes it disappear
doing some of this from memory as my pi is misbehaving. Are you familiar with the linux command line?
nope
don't worry ... I will install without ratos
I cannot ask you to loose so much time.
I got laid off a few weeks ago, I do have more time nowadays 😛
but I do need to run some errands. If you get it working with vanilla klipper, I'd be curious what you end up with in this section:
I have this already in ratos.cfg
right, but it isn't working. So I want to know what value does work
I have change it by serial: /dev/serial/by-id/usb-Klipper_stm32f407xx_prusa-buddy-if00
but still the same error mcu
is there a file in that directory?
Can do a
cd /dev/serai/by-id then lsIt s ok now … thanks for help
