# This file contains common pin mappings for the BIGTREETECH SKR mini
# E3 v3.0. To use this config, the firmware should be compiled for the
# STM32G0B1 with a "8KiB bootloader" and USB communication/USART.

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

algorithm: bicubic
fade_start: 1
fade_end: 10
#fade_target:
#   The z position in which fade should converge. When this value is set
#   to a non-zero value it must be within the range of z-values in the mesh.
#   Users that wish to converge to the z homing position should set this to 0.
#   Default is the average z value of the mesh.
split_delta_z: 0.015
#   The amount of Z difference (in mm) along a move that will
#   trigger a split. Default is .025.
move_check_distance: 3
#   The distance (in mm) along a move to check for split_delta_z.
#   This is also the minimum length that a move can be split. Default
#   is 5.0.
mesh_pps: 4,4
#   A comma separated pair of integers (X,Y) defining the number of
#   points per segment to interpolate in the mesh along each axis. A
#   "segment" can be defined as the space between each probed
#   point. The user may enter a single value which will be applied
#   to both axes.  Default is 2,2.
#bicubic_tension: .2
#   When using the bicubic algorithm the tension parameter above
#   may be applied to change the amount of slope interpolated.
#   Larger numbers will increase the amount of slope, which
#   results in more curvature in the mesh. Default is .2.
