# Sample macro config to be used in conjunction with the Decontaminator Purge Bucket & Nozzle Scrubber mod. Created by Hernsl
|
|
# (hernsl#8860 on Voron Design discord) and edited by Edwardyeeks (edwardyeeks#6042 on Voron Design Discord).
|
|
|
|
# The goal of this macro is to provide a nozzle scrubbing and purging routine that is easily copied/referenced into your printer.cfg.
|
|
# Users can simply change parameters and enable/disable options in the first half. Descriptions are laid out in sequence to be read
|
|
# first; PLEASE READ CAREFULLY.
|
|
|
|
# This sample config assumes the following: The user has implemented the default decontaminator purge bucket & nozzle scrubber mod
|
|
# for the VORON 1/2.
|
|
|
|
# Features in this macro: option of putting the bucket at the rear or front of the bed. Purge routine that can be enabled/disabled.
|
|
# By default, bucket is located at rear left of bed and purge routine is enabled.
|
|
|
|
# Default parameters are set for safe speeds and movements. Where necessary, tweak the parameters for the nozzle scrub procedure
|
|
# to fit your printer.
|
|
|
|
# To avoid adding length of lines to your main printer.cfg config file, one can upload a config file separately into klipper and
|
|
# include it into the main printer config. Upload nozzle_scrub.cfg to the same directory as printer.cfg. Usually, it is in /home/pi/.
|
|
|
|
# Once uploaded, add the following to your printer.cfg in the Macros section: [include /home/pi/nozzle_scrub.cfg]
|
|
# Those running mainsail will need to use the following location instead: [include /home/pi/klipper_config/nozzle_scrub.cfg]
