KBobine

Warning

This repo is still at work, doc is uncomplete and code can present some bugs, use it whith care

Kbobine is a gateway between Spoolman and Klipper, it allows to send current spool informations to Klipper. Then, it let you store settings inside Klipper configuration.

Compatibility: Fluidd/Klipperscreen/Mainsail UI.

Requirements: a working Spoolman component in Moonraker

Fluidd	KlipperScreen	Mainsail

What it does ?

At Klipper startup or when a spool is selected (by UI or macro), it informs Klipper and send back informations from Spoolman to klipper (material, vendor, name of the filament, ...). Then Klipper apply settings previously set for this spool. If no information found, settings from equivalent spool/material/default can be imported.

Note

With the minimal install you can use kbobine just to share information between klipper and spoolman. More informations on how spoolman_ext.py works

What kind of settings ?

Pressure advance and firmware retraction was the first parameters introduced in early version. But you can store any settings you need in your Macros. For example, I store temperatures, filter use, filament sensor use, extrude_factor... I use some extended functions to limit max_flow and fan_speed during the print.

Why store the settings inside Klipper config instead of Spoolman ?

These settings are mostly printer/toolhead dependent. It also allows you to call settings even if connexion to spoolman is lost.

How it works ?

KBobine use a moonraker component spoolman_ext.py to track spool change then send informations about spool to klipper. It stores infos about spool in a saved_variable array kbobine_table once the spool is loaded. If no setting is detected, it will prompt to calibrate filament or load settings from other filaments in table. Then it populates a current_settings array from default settings and stored settings. This array can be called from your Macros like this:

{% set settings = printer['gcode_macro _KBOBINE'].current_settings %}

How to install it ?

Clone the repo

First clone the current repo on your printer

cd ~
git clone https://github.com/fbeauKmi/kbobine_filament_settings.git kbobine
cd kbobine

Run the installer

Usage: bash install.sh [-0|--option]

Kbobine installer

Optional args:
  -m, --minimal              Install moonraker component only.
  -f, --force                Force Moonraker component installation.
  -h, --help                 Display this help message and exit.

Warning

The script does not restart Klipper/Moonraker, you will have to do it manually once done.

sudo systemctl restart klipper
sudo systemctl restart moonraker

Uninstall it

Remove Moonraker component, delete kbobine folder, Manually remove entries in moonraker.conf and klipper config

 unlink ~/moonraker/moonraker/components/spoolman_ext.py
 rm -rf ~/kbobine

How to use it ?

• Kbobine Configuration and usage
• Simple Use case : Check in PRINT_START if a spool is selected
