Hi, I tried to install numpy which ran fine, but when I came to make the mcu and stop the klipper service I got the following error: Failed to stop klipper.service: Unit klipper.service not loaded. I tried to carry on with the makeflash etc, but on the ‘Save and Restart’ of the printer, klipper could not start. (Has anyone else had this issue?)
hard to say from the little information. the service was not loaded when you installed numpy. I guess you are trying to add the input shaper? Have you rebooted? Is klipper online now?
Hello,
Yes I was in the process of installing input shaper. Numpy installed fine (I presume), but when I had this error when I tried to stop/start the service. I had prepared the RPI as an MCU and was trying to flash it, when I added the ‘RPI MCU section’ to my printer.cfg and restarted the printer the host would not boot. I had to then comment out the ‘RPI MCU’ restated and the host was available again.
Could this be something to do with the service not stopping correctly? When doing the ‘make flash’?
Can I uninstall Numpy and all the dependencies and try it again? If so what are the commands to do this?
Many thanks
Michael
you probably haven’t installed the RPI MCU correctly. That has nothing to do with numpy.
have you followed these instructions?
Yep, I followed the instructions on the Kilpper website on how to install input shaper. Numpy installed fine but it was the stopping of the service that didn’t work when I can to flash the RPI MCU part.
Many thanks
Michael
if it’s not stopping it’s because it’s already stopped 
Ok, but I then couldn’t start the service again… And this was after restarting Klipper
Many thanks
Michael
can you send some logs of when the mcu is failing? I’m fairly certain rpi mcu failed to install somehow
Would that be the Klippy.log file? Sorry, I’m very new to Klipper and Voron.
I’m at work at the moment but can certainly get you the logs when I get home.
Many thanks for your help. I really appreciate it.
Michael
yes let’s start from the klippy.log
Hi,
Please see the attached.
(Attachment klippy-1 (1).log is missing)
Hi,
I attempted to attach the klippy logs but apparently, it’s an invalid file type to attach to discourse!!! Is there another way??
it shouldn’t be too big. just paste it inside a
code tag
otherwise use pastebin

that’s the log of the working machine. when it is working, connect to SSH, stop the service, make menuconfig and select “linux process” from the list, then make flash.
then enable the mcu process
sudo cp ~/klipper/scripts/klipper-mcu-start.sh /etc/init.d/klipper_mcu
sudo update-rc.d klipper_mcu defaults
Add the [mcu rpi] to your configuration and at this point you can restart the klipper service.
If it’s not working send the log. Please enclose the log into a code tag.
Hi,
Thank you so much for you help. I ended up reinstalling mainsail and Klipper and then started the whole process again and it now seems to be working. I’ve not yet connected the ADXL board and tried input shaper but hopefully the software side is sorted now.
May I ask you another question? I have the SKR E3 Turbo and I’m trying to get the LCD to work. It requires the spi pins but there isn’t any physical pins so it requires the software pins enabled. But I don’t know how you reference these pins nor what their pin assignments are.
Any help would be greatly appreciated.
Many thanks
Michael
you mean software SPI? This is a good start klipper/sample-lcd.cfg at master · KevinOConnor/klipper · GitHub
