Basic Information: Printer Model: Made by me MCU / Printerboard: Mks Robin Nano and BTT SKR 1.4 TURBO klippy.log (1.2 MB) klippy.log Hello, my name is Alfredo Collie and I am from Venezuela, I hope you are doing very well, I installed Klipper on 2 machines on a MKS Pi v1.1, both print perfect…

Hello @alfredcollie ! The Klipper is a firmware solution that splits into two parts: The host on the SBC/PC that does the calculation work And the client that runs on the printer’s mainboard and does the connection to the hardware So both make one unit an can not be separated. For your second p…

I have 2 instances of klipper installed

I see. I assume you stick to this information, yes? https://www.klipper3d.org/FAQ.html#can-i-run-multiple-instances-of-klipper-on-the-same-host-machine

According to your log it seems the troublemaker is the host MCU according to RPi microcontroller - Klipper documentation Depending on your Linux skills, you need to either: Duplicate them to have two instances with two different endpoints OR Deactivate it in one of your configs, this means remove…

I already have created two instances of klipper and moonraker I deleted [mcu rpi] from one of the printer.cfg and it no longer connects What else can I do

Deleting the entire [mcu rpi] section will not cause a malfunctioning connection between Klipper and board. Post a new klippy.log

This is the message that appears when removing MCU RPI Unknown pin chip name ‘rpi’ I can’t send the klippy.log it’s too big

Archive klippy.log klippy (1).log 1 file sent via WeTransfer, the simplest way to send your files around the world

Adding the RPI MCU again connects the printer immediately

You need to remove [adxl345] cs_pin = rpi:None spi_bus = spidev0.2 in this case as well
