printer-20200321_140741.cfg

# This file contains common pin mappings for the BIGTREETECH SKR mini
# E3 v1.2. 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 "!PC13".

# 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.

#max_extrude_cross_section:
#   Maximum area (in mm^2) of an extrusion cross section (eg,
#   extrusion width multiplied by layer height). This setting prevents
#   excessive amounts of extrusion during relatively small XY moves.
#   If a move requests an extrusion rate that would exceed this value
#   it will cause an error to be returned. The default is: 4.0 *
#   nozzle_diameter^2
#instantaneous_corner_velocity: 1.000
#   The maximum instantaneous velocity change (in mm/s) of the
#   extruder during the junction of two moves. The default is 1mm/s.
max_extrude_only_distance: 100.0
#   Maximum length (in mm of raw filament) that a retraction or
#   extrude-only move may have. If a retraction or extrude-only move
#   requests a distance greater than this value it will cause an error
#   to be returned. The default is 50mm.
#max_extrude_only_velocity:
#max_extrude_only_accel:
#   Maximum velocity (in mm/s) and acceleration (in mm/s^2) of the
#   extruder motor for retractions and extrude-only moves. These
#   settings do not have any impact on normal printing moves. If not
#   specified then they are calculated to match the limit an XY
#   printing move with a cross section of 4.0*nozzle_diameter^2 would
#   have.
#PLA
#pressure_advance: 0.6528
#PETG
pressure_advance: 0.84
#   The amount of raw filament to push into the extruder during
#   extruder acceleration. An equal amount of filament is retracted
#   during deceleration. It is measured in millimeters per
#   millimeter/second. The default is 0, which disables pressure
#   advance.
pressure_advance_smooth_time: 0.040
#   A time range (in seconds) to use when calculating the average
#   extruder velocity for pressure advance. A larger value results in
#   smoother extruder movements. This parameter may not exceed 200ms.
#   This setting only applies if pressure_advance is non-zero. The
#   default is 0.040 (40 milliseconds).
#
#
[verify_heater extruder]
# Heater and temperature sensor verification. Heater verification is
# automatically enabled for each heater that is configured on the
# printer. Use verify_heater sections to change the default settings.
#[verify_heater heater_config_name]
heating_gain: 0.5
#   The minimum temperature (in Celsius) that the heater must increase
#   by when approaching a new target temperature. The default is 2.
check_gain_time: 40
#   The amount of time (in seconds) that the heating_gain must be met
#   in before an error is raised. The default is 20 seconds for
#   extruders and 60 seconds for heater_bed.
hysteresis: 3
#   The difference between the target temperature and the current
#   temperature for the heater to be considered within range of the
#   target temperature. The default is 5.
#max_error: 120
#   The maximum temperature difference a heater that falls outside the
#   target temperature range may accumulate before an error is
#   raised. For example, if the target temperature is 200, the
#   hysteresis is 5, the max_error is 120, and the temperature is
#   reported at 185 degrees for 12 seconds then an error would be
#   raised (or 24 seconds at 190, or 120 seconds at 194, etc.). The
#   default is 120.
