I am a bit of a loss as to why i try to calibrate beacon and unable to save_config. Unless i solve this problem I am unable to progress. BTW i am a retired person in their mid 70"s using 3D printing as a way to take up my retirement. I have never asked for help before unless i really need it but have limited experience.
This file contains common pin mappings for the BigTreeTech Octopus V1.
To use this config, the firmware should be compiled for the STM32F446 with a “32KiB bootloader”
Enable “extra low-level configuration options” and select the “12MHz crystal” as clock reference
after running “make”, copy the generated “klipper/out/klipper.bin” file to a
file named “firmware.bin” on an SD card and then restart the OctoPus with that SD card.
See docs/Config_Reference.md for a description of parameters.
