printer.cfg

# This file contains common pin mappings for the BIGTREETECH SKR mini
# E3 v2.0. To use this config, the firmware should be compiled for the
# STM32F103 with a "28KiB bootloader". Also, select "Enable extra
# low-level configuration options" and configure "GPIO pins to set at
# micro-controller startup" to "!PA14".

# The "make flash" command does not work on the SKR mini E3. Instead,
# after running "make", copy the generated "out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the SKR
# mini E3 with that SD card.

# See the example.cfg file for a description of available parameters.

#   The micro-controller to read from. The default is "mcu".

#sensor_adc1:
#   Specify the above two parameters (a temperature in Celsius and an
#   ADC value as a float between 0.0 and 1.0) to calibrate the
#   micro-controller temperature. This may improve the reported
#   temperature accuracy on some chips. A typical way to obtain this
#   calibration information is to completely remove power from the
#   printer for a few hours (to ensure it is at the ambient
#   temperature), then power it up and use the QUERY_ADC command to
#   obtain an ADC measurement. Use some other temperature sensor on
#   the printer to find the corresponding ambient temperature. The
#   default is to use the factory calibration data on the
#   micro-controller (if applicable) or the nominal values from the
#   micro-controller specification.
#sensor_temperature2:
#sensor_adc2:
#   If sensor_temperature1/sensor_adc1 is specified then one may also
#   specify sensor_temperature2/sensor_adc2 calibration data. Doing so
#   may provide calibrated "temperature slope" information. The
#   default is to use the factory calibration data on the
#   micro-controller (if applicable) or the nominal values from the
#   micro-controller specification.

#   is True.

#   A list of G-Code commands to execute after a filament runout is
#   detected. See docs/Command_Templates.md for G-Code format. If
#   pause_on_runout is set to True this G-Code will run after the

#insert_gcode:
#   A list of G-Code commands to execute after a filament insert is
#   detected. See docs/Command_Templates.md for G-Code format. The
#   default is not to run any G-Code commands, which disables insert
#   detection.
event_delay: 3.0
#   The minimum amount of time in seconds to delay between events.
#   Events triggered during this time period will be silently
#   ignored. The default is 3 seconds.
pause_delay: 5
#   The amount of time to delay, in seconds, between the pause command
#   dispatch and execution of the runout_gcode. It may be useful to
#   increase this delay if OctoPrint exhibits strange pause behavior.
#   Default is 0.5 seconds.
