M300

[klaas1979]

I tried to install the scripts on an Ender 6 with a Hemera XS modificatation. The base setup is from 3dprintingforbeginners. I get the following error, after starting the firmware:

gcode command M300 already registered

Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
Printer is halted

I cannot find any M300 command defined, beside in the beep.cfg

Setup was done by git cloning in the path ~/printer_data/config/klipper-macros.

As I am a newbie to 3d printing and klipper, I am lost where to search in my configurations. Can you help and provide some directions?

My printer.cfg:

# This file contains pin mappings for the stock 2020 Creality Ender 6.
# To use this config, during "make menuconfig" select the
# STM32F103 with a "28KiB bootloader" and with "Use USB for
# communication" disabled.

# Because this printer has factory wiring, mounts, and firmware for
# a BLTouch, but does not ship with one at this time, default values
# for the sensor have been specified, but disabled, in anticipation of
# future revisions or user modification. User should take care to
# customize the offsets, particularly z-offset, for their specific unit.

# If you prefer a direct serial connection, in "make menuconfig"
# select "Enable extra low-level configuration options" and select the
# USART3 serial port, which is broken out on the 10 pin IDC cable used
# for the LCD module as follows:
# 3: Tx, 4: Rx, 9: GND, 10: VCC

# Flash this firmware by copying "out/klipper.bin" to a SD card and
# turning on the printer with the card inserted. The firmware
# filename must end in ".bin" and must not match the last filename
# that was flashed.

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

I moved beep.cfg. Now the configuration loads. I am using https://github.com/Desuuuu/DGUS-reloaded-Klipper to have the custom screen of the Ender 6 available. Maybe this can be the problem where the command is defined.

[jschuh]

The fork you're using adds a native m300 command, whereas mainline Klipper requires m300 to be defined via a macro. Unfortunately, there's no way to be simultaneously compatible with both (because Klipper doesn't have a conditional mechanism for macro definitions or file includes). This is just an unfortunate reality of running a fork: any changes the fork makes may introduce incompatibilities with the mainline. So, the only real option is to remove the beep.cfg file (as you have).

[klaas1979]

Thank you very much for the fast reply and locking into it. I will probaly get a compatible screen someday.
