klipper-dgus/config/printer-monoprice-mini-delta-2017.cfg

# This file contains common pin mappings for the 2017 Monoprice
# Mini Delta. To use this config, the firmware should be compiled for the
# STM32F070 microcontroller with an 8MHz crystal and USB for communication
# (instead of serial).
#
# IMPORTANT: Use of Kipper with a Monoprice Mini Delta requires a power supply
# with a _minimum_ 120 W (i.e. 10 A) capacity! The stock power supply will not
# work, as it can't power the hotend and the bed at the same time.
#
# Note 1: Some controller boards only trigger the bootloader when an update file
# is "printed" from the LCD, rather than supporting bootloader triggering
# during bootup. It may be preferable to use an ST-Link V2 to flash the
# firmware instead. Follow this link for an example of the commands needed to
# do this: https://github.com/arkorobotics/MiniDeltaBootloader
#
# Note 2: Klipper does not currently support the LCD interface used on this
# printer.
#
# See docs/Config_Reference.md for a description of parameters.


# Stepper A is the front-left tower, as originally wired. If you've rewired
# your steppers to "correct" this, you'll need to swap these values.

    M140 S0 ; turn off bed heater
    G91 ; Switch to use Relative Coordinates
    G1 E-3 F700 ; retract the filament a bit before lifting the nozzle to release some of the pressure
    G1 Z2 F1000 ; raise platform 2mm from current position
    G1 E-2 F700 ; retract filament even more
    G90 ; Switch back to using absolute coordinates
    G28 X Y Z ; Return to home position. Without an X Y or Z after G28 the print completion time will not be displayed on the Mini Delta's display.
    M84 ; disable motors
    M107 ; turn off fan. Don't use M106 S1. Using M106 S1 may prevent the fan from turning on for the following print. Some say M107 doesn't work for them but if the hotend is below 70 degrees it should work
