Mainsail klipper setup for rpizero and btt pico

[quartz hound]

Evening,
I have an ender 3 v2 and i'm trying to set up a raspberry pi zer w2 and a btt pico v1. I have mainsailos installed on the zero but i'm trying to compile the uf2 for the bttpico and i can not find the firmware option to compile the correct firmware for the pico.

its connected to the pi via uart and i'm following instructions as best I can but I think i'm missing something.

Mainsail is still giving me an MCU error as well so i'm guessing that my have smething to do with it??? this is my first really foray into 3d printers so please be gentle

hey there... fix your config. the format is not just random lines. its yaml and follow somes rules to get parsed:

here an example config for your pico board: https://github.com/Klipper3d/klipper/blob/master/config/generic-bigtreetech-skr-pico-v1.0.cfg

this is was klipper sees from your printer.cfg shown on the screenshot

ah, well that probablly would help, they do say to double check chatgpt's work

[remote sonnet]

and they are right...

also check the path of the mcu. thats an usb path and not the uart.

[quartz hound]

its no longer spitting out an error screen 🙂

[quartz hound]

and now it does again, im confused again

[mcu]
serial = /dev/serial/by-id/usb-Klipper_Klipper_firmware_12345-if00

thats still a usb path

next question would be did you flash the mcu with klippper?

I loaded the uart uf2 but i haven't done step 5.. that one confuses me

are they saying to modify the mainsail sdcard?

[remote sonnet]

step v tells you how you get the uf2 file from your pi to flash it on the pico

if you mean the step 5 under the build firmware topic

if you mean the step 5 from the configure printer paramters. it tells you indeed to change th esettings on your mainsail sd card. this can be done via ssh from the pi itself. no need to plug it into your computer.

[quartz hound]

yeah step 5 for printer parameters.

i guess i'll have to do that

[quartz hound]

Ok so the few hours ive confirmed the btt pico is flashed with the uart.uf2 fron https://github.com/bigtreetech/SKR-Pico/tree/master/Klipper

I used a laptop as I couldn't SSH to the zero as I couldn't get the user/pwd combo correct

I've done step 5 of the last part adjusting the files. the first didn't have the line to remove and I added the line to the second.

And I'm still getting mcu errors.

To say I'm scratching my head is an understatement

[hexed oracle]

You should definitely reflash the sdcard of the pi, if you don't know your username+password. You didn't install+setup that much, so now is the best time to reflash to set your username+password to something you know

[quartz hound]

Well I just figured out why SSH wasn't working, raspberry pi imager has SSH odd by default ☹️
