# This file contains pin mappings and other appropriate default parameters
|
||||
# for a Wanhao Duplicator i3 v2.1 and its clones
|
||||
# (Monoprice Maker Select, Cocoon Create, etc.)
|
||||
# See the files example.cfg and example-extras.cfg for a description of available parameters.
|
||||
#
|
||||
# This will probably work on older revisions (v1.0, v2.0) of the printer
|
||||
# but is untested on those versions.
|
||||
#
|
||||
# For best results with klipper and the Wanhao Duplicator i3, follow these
|
||||
# guidelines:
|
||||
#
|
||||
# - Flash a bootloader to the Melzi board in the printer
|
||||
# See http://www.instructables.com/id/Using-an-Arduino-to-Flash-the-Melzi-Board-Wanhao-I/
|
||||
#
|
||||
# - Make sure the auto-reset jumper is *enabled* on the Melzi board
|
||||
# (See step 1 in the bootloader tutorial above)
|
||||
#
|
||||
# - Locate the USB serial port for your printer in /dev/serial/by-id/ format.
|
||||
# See https://github.com/KevinOConnor/klipper/blob/master/docs/FAQ.md#wheres-my-serial-port
|
||||
# It will be something like:
|
||||
# /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_ABCD1234-if00-port0
|
||||
#
|
||||
# - Configure klipper to compile firmware for the AVR atmega1284p
|
||||
#
|
||||
# - At this point, "make flash FLASH_DEVICE=..." should successfully
|
||||
# flash your printer board. Use the /dev/serial/by-id/ format for
|
||||
# FLASH_DEVICE to ensure consistent results.
|
||||
# See https://github.com/KevinOConnor/klipper/blob/master/docs/FAQ.md#the-make-flash-command-doesnt-work
|
||||
# if you have problems.
|
||||
#
|
||||
# - Copy this sample file you are currently reading to ~/printer.cfg,
|
||||
# and customize the following parameters:
|
||||
# * [extruder] > step_distance
|
||||
#
|
||||
# This is the inverse of "E steps" (extruder steps per mm) from the stock
|
||||
# Wanhao Repetier-based firmware.
|
||||
# (See https://3dprinterwiki.info/extruder-steps/ )
|
||||
#
|
||||
# For example, if your E-steps are set to 107.0 steps per mm,
|
||||
# then step_distance should be (1 / 107.0) ~= .009346
|
||||
#
|
||||
# * [extruder] > PID parameters (pid_Kp, pid_Ki, pid_Kd)
|
||||
# * [heater_bed] > PID parameters (pid_Kp, pid_Ki, pid_Kd)
|
||||
#
|
||||
# PID values from stock Wanhao firmware (Repetier) do not
|
||||
# translate directly to klipper. You will need to run klipper's
|
||||
# PID autotune function for the extruder and bed. After getting the
|
||||
# klipper firmware up and running, run the M303 autotune procedures
|
||||
# by sending these commands via octoprint terminal (one per autotune):
|
||||
#
|
||||
# extruder: M303 E0 S<temp>
|
||||
# heated bed: M303 E-1 S<temp>
|
||||
#
|
||||
# After the autotune process completes, PID parameter results
|
||||
# can be found in the Octoprint terminal tab (if you're quick)
|
||||
# or in /tmp/klippy.log.
|
||||
#
|
||||
# Enter the PID parameters into the appropriate sections of ~/printer.cfg .
|
||||
#
|
||||
# * [extruder] > max_temp
|
||||
# * [heater_bed] > max_temp
|
||||
#
|
||||
# The max temps included in this printer config are limited to 230 for extruder
|
||||
# and 70 for heated bed. If your printer has been modified to handle higher temps
|
||||
# (like an upgraded hot end or a separate MOSFET for your heated bed), you may
|
||||
# want to increase these values.
|
||||
#
|
||||
# * [mcu] > serial
|
||||
#
|
||||
# Enter the USB serial port of the printer in /dev/serial/by-id/ format
|
||||
# for best results.
|
||||
#
|
||||
# - Power cycle the Wanhao Duplicator i3
|
||||
#
|
||||
# - Issue the command "RESTART" via the Octoprint terminal tab (similar to
|
||||
# how you would send a manual gcode command, but send the word RESTART).
|
||||
# This tells klipper to reload its config file and do an internal reset.
|
||||
# You should then see a status screen appear on the printer's LCD.
|
||||
#
|
||||
# - Be sure to follow these instructions before attempting any prints:
|
||||
