All set but no comm between spider 3 board and raspberry (no MCU at mainsal)

[ErickSobreiro]

Hello, after installing the firmware, with the correct serial number in the printer.cfc, the mainsall identifies the USB and board but the MCU does not connect to the interface. Need assistence!

Evidences attached

Thank you

[cyberjak2k]

Have you fixed the error it reported to you in your printer.cfg?

[ErickSobreiro]

yes, as there is nothing connected to the board, I deleted the entire cfg but the lack of communication remains. even with the errors the MCU description should appear. Thank you

[cyberjak2k]

Can you post your printer.cfg?
If it helps I'm also in the FYSETC discord as well as their Facebook messenger chat group

[ErickSobreiro]

sure, its a default CFG - the only change now is "serial", first step, test the connection and then start editing the cfg.

This file contains common pin mappings for the Fysetc Spider board.

To use this config, the firmware should be compiled for the STM32F446.

When calling "menuconfig", enable "extra low-level configuration setup"

and select the "12MHz crystal" as clock reference

For flashing, write the compiled klipper.bin to memory location 0x08000000

See docs/Config_Reference.md for a description of parameters.

Uncomment below if you're using the Raspberry uart0 to communicate with Spider

#restart_method: command

You need to select 'Communication interface' to USB in 'make menuconfig'

when you compile Klipper for Spider

Obtain definition by "ls -l /dev/serial/by-id/" then unplug to verify

##--------------------------------------------------------------------

If you want to use the Raspberry uart0 to communicate with Spider,

you need to select 'Communication interface' to 'Serial (on USART1 PA10/PA9)'

in 'make menuconfig' when you compile klipper and set the serial as below

##--------------------------------------------------------------------

ok I looked at the Spider 3 printer config as the darn hash comments go bold so hard to tell , but the error suggests tht line 397 is the problem.
I'm going to suspect it's however you edited it added some invisible characters to the end of that line.
goto line 397 , goto the very end of the line and hit backspace till the cursor deletes the last letter or character in it, then manually type that chacter back in , save it, and restart ( failing this I need you to upload the file instead of copying it in ) but it's defeinitly a problem in the config after editing

[ErickSobreiro]

Its interesting, because the error still there.

Following attached all cfg files. Thank you very much!

config-20250512-173110.zip

[cyberjak2k]

Ok give me some time to look these over ( probaby will be tomorrow before I can answer further ) I have the same board in my self designed printer ( Voron inspired ) so there shouold be a LOT of things that match up ,

[cyberjak2k]

Actually I took a quick look. Here is your problem

If you look at line 397 it doesn't have a # in front of it so Klipper failed to understand.
Start using notepad++ to edit configs in future as it will also help by showing you the line numbers which clipper told you it was line 397
So just put # to the left of that line so it's commented out

[ErickSobreiro]

many thanks, its working!
