Introduction

This is a fork of RatOS-Configuration repo that adds support for Voron printers. Currently, only the Voron Trident is supported.

Features

• Support for my specific Voron Trident 250 (see Assumptions below)
• Adds two new variables (see New Variables below):
  • Optional "motors off" at print end
  • Support for textured plates in the print start command to apply a configurable Z-offset
• Modified the Z-calibration sequence to work with Protoloft's auto Z-calibration
• This repo can be used across multiple printers without any modifications
  • Instead of using the default printer.cfg file you can have printer-<name1..n>.cfg (see Install section)

Assumptions

• Choice of Klicky as the z-probe
  • The included template might be compatible with other z-probes, but is untested (PRs welcome)
• Mainsail OS or FluiddPi as the base install
  • RatOS itself is not used, only the configuration files
  • RatOS might work, but is untested
• LDO 42STH48-2504AC A & B motors
  • BOM calls for LDO 42STH40-2004MAH (PRs welcome)
• Fysetc Spider v1.1 controller
  • Other MCUs haven't been tested (PRs welcome)

Install

• Setup Raspberry Pi using the method of your choice
  • Following either the Mainsail OS or FluiddPi installation instructions is recommended
• Chose a unique name for your printer which will be referenced as <name> below
• SSH to your Raspberry Pi and change directory to klipper_config:

  • ssh pi@<hostname>.local
    cd ~/klipper_config

• Clone repo:

  • git clone https://github.com/AdamYellen/RatOS-Configuration config

• Copy the included template:

  • cp config/templates/voron-trident-klicky.template.cfg printer-<name>.cfg

• Modify the mcu setting at the bottom of printer-<name>.cfg
  • Hint: ls /dev/serial/by-id/
• Install klipper_z_calibration
• Install Klicky Probe macros in a specific sub-directory:

  •  git clone https://github.com/AdamYellen/Klicky-Probe-macros.git klicky-probe

• Modify the klipper args to reference the named printer config file and restart Klipper
  • There are two ways to edit this reference based on how Klipper was installed
    • Edit the KLIPPY_ARGS line in /etc/defaults/klipper:

    • KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/klipper_config/printer-<name>.cfg -l /tmp/klippy.log -a /tmp/klippy_uds"

    • Restart Klipper:

    • sudo /etc/init.d/klipper restart

  • OR
    • Edit the KLIPPER_CONFIG line in /etc/systemd/system/klipper.service:

    • Environment=KLIPPER_CONFIG=/home/pi/klipper_config/printer-<name>.cfg

    • Restart Klipper:

    • sudo systemctl restart klipper

• Use your interface of choice (Mainsail, Fluidd, nano, vi, etc.) to edit the copied template to suit your needs

New Variables

• Add TEXTUREDPLATE=true to your slicer's PRINT_START command and adjust variable_textured_plate_offset in the config file
  • This is an additional Z-offset that will be applied after Z-probing
• Enable or disable the motors off variable (variable_end_print_motors_off) in the config file to control that behavior
  • Defaults to True
