Hi all,

Getting an MCU uable to connect error (this is my first attempt at setting up klipper and I’m using mainsail os) I do the following (I have tried multiple usb cables too):

My make menu config is this:

Then I use ‘make’

then I turn off klipper and run this command to flash my board:
avrdude -p atmega1284p -c arduino -P /dev/ttyUSB0 -b 115200 -U flash:w:out/klipper.elf.hex

then I get this which looks like it runs ok to me:

avrdude: AVR device initialized and ready to accept instructions

avrdude: Device signature = 0x1e9705 (probably m1284p)

avrdude done. Thank you.

(appologies for the long text rather than a screenshot, I can only include one image as I am a new user)
I restart klipper and I get the error message

for reference my ls /dev/serial/by-id/ command returns: usb-1a86_USB_Serial-if00-port0

Has anybody else had this issue or have any advice?

Thanks!

Hello @raincoatnoun !

Why avrdude?

Did this not work for you?

sudo service klipper stop
make flash FLASH_DEVICE=/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0
sudo service klipper start

Hi @EddyMI3D
Thanks for you response!
avrdude was recommended in the config file
When I used make flash I was getting an error. Which seems to be gone now
This is the response:
Flashing out/klipper.elf.hex to /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 via avrdude

I’m still getting what looks like the same MCU error though

You had that already in you first post.

You got that from where?

BTW: For code, please use the Preformatted Text feature of the forum editor:

Yes I did, it was the same response

I got the config file from here:

Thanks fo the advice about using the preformatted text feature!

For future users, I have solved this issue!
I used this make menuconfig:

Used this to flash the bios (thanks @EddyMI3D for getting me to try it again!)

sudo service klipper stop
make flash FLASH_DEVICE=/dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
sudo service klipper start

Then changed added

[include mainsailos]

and corrected the serial by-id part of the printer config, my printer config now looks like this:
printer.cfg (2.4 KB)

Hope this helps somebody else!
