Documentation is being finalized, 2.1.0 will be released as release candidates (pre-releases) until it's done.

Update all packages after connecting RatOS to your wifi network. Follow the installation instructions, and pay close attention to the update process.

Changes from RC1

Tons of bugfixes for boards, drivers non-standard sense resistors and general functionality
Realtime Analysis Tool now does input shaper calibration, belt tension peak detection and mechanical health estimation on macro recordings. It also shows you g-code response output while running macro's. Performance have been significantly improved, video memory requirements are significantly lower and should allow longer macro recordings on lower end graphics hardware.
Full one macro beacon contact auto calibration including scan compensation using BEACON_RATOS_CALIBRATE
More boards added.
Improved diff dialog and file change handling in wizard.

Expanding the configurator - Klipper configuration generator.

RatOS now simplifies the klipper configuration process by automatically generating and updating the RatOS.cfg file based on your selections in the configurator. This file becomes the sole inclusion in printer.cfg, eliminating the need for managing multiple includes or modifying lines of code. RatOS intelligently recognizes your hardware and adjusts the configuration and macros accordingly.

Should you make any changes to your hardware, RatOS will simply update RatOS.cfg and display the changes for your review. This ensures that your have more confidence in tinkering, and can try out new things quickly without worrying about configuration.

Features

Point and click klipper config generation
The wizard will now ask you about your hardware configuration
- Select from 12 printers and 32 control boards
- Configure toolhead hardware (up to 2 toolheads per printer)
- Support for multiple instances of 12 supported toolboards.
- Printer configuration
- Motor / driver configuration
  - Reconfigurable motor slot allocations, you decide which slot is used for which axis.
  - Supports 24V, 36V, 48V, 56V, and 60V setups
  - Supports a variety of 2130, 2209, 2240, 2160 and 5160 drivers.
  - Supports a variety of stepper motors, including a "generic" stepper using klipper defaults.
  - Current adjustment
  - Automatically applied tuning presets for known configurations.
RatOS.cfg does not use pin aliases, the pins match the board's pinout diagram.

Expanding the configurator - beyond the wizard

RatOS 2.1 has evolved into a comprehensive application that interfaces with Klipper and Moonraker. It is set to expand its capabilities with various tools aimed at enhancing interactive analysis and calibration. The initial offerings will include VAOC (Visually Assisted Offset Calibration) and RAT (Realtime Analysis Tool), promising to elevate the user experience further.

Realtime Analysis Tool (RAT)

Power spectral density graphs, live, real-time, in your browser!

Create your own macros for analysing different aspects of your printer.
Hunt down sources of mechanical issues using the Oscillator by monitoring the realtime PSD while touching different parts of your motion system.
Works on phones, use it like a Star Trek Tricorder.
Supplies two new g-code commands, OSCILLATE and GENERATE_RESONANCES.

IDEX Support

Helge Keck's outstanding contributions to RatOS 2.1 have made all RatOS macros fully IDEX compatible, offering numerous advantages compared to other implementations.

Toolshift

RatOS features an integrated gcode postprocessor compatible with PrusaSlicer, OrcaSlicer, and SuperSlicer. It leverages the rapid toolshift macros for synchronous toolhead swapping and advancing to the subsequent print position in just two swift actions. This results in almost instantaneous tool changes, drastically cutting down on the time typically required for purge towers, and may even render them unnecessary. Additionally, Toolshift is customizable to execute a hotend purge during a tool change if the upcoming toolhead has been inactive past a predefined duration.

Intelligent priming / purging
Single toolhead + spool join mode
Multi color mode
Copy/Mirror mode
Experimental auto centering of print on the build plate for copy and mirror mode
Toolhead remapping
IDEX aware SET_PRESSURE_ADVANCE with toolhead syncing capabilities
Automatic toolhead deactivation after last use in print.
Fan synchronization
Optional automatic toolhead standby
Retraction control
Fully automated z-offset calibration before printing
Live speed and acceleration control while printing

Visually Assisted Offset Calibration (VAOC)

RatOS features a Visually Assisted Offset Calibration interface, complete with z offset probe support, making toolhead offset calibration a breeze, blazing fast and extremely precise.

Single Toolhead Hybrid CoreXY support

RatOS is equipped with specialized Hybrid CoreXY kinematics, which include the capability to operate two additional Cartesian motors on the Y-axis. This feature significantly enhances performance scaling in CoreXY configurations. By carefully tensioning the belts, users can achieve more than a twofold increase in the recommended shaper accelerations for the Y-axis.

Macros: new built-in features

Beacon contact auto calibration
Automatic hotend/nozzle thermal expansion calibration (Beacon Contact or Z offset probe)
Primeblob is now significantly faster, takes less space and adapts to nozzle size.
Sensorless homing supported for all driver types.

* Insert, runout and clog detection
- Automatic loading / unloading with on-toolhead sensor
- Automatic print resume on insert
- Optional purge before unload or after load
- Sanity checks before print starts, checks for filament presence
- Filament grabbing on insert even if the hotend is cold
- Filament status color in Mainsail
Hotend type and nozzle aware tip forming when unloading
New calibratron macros, PID tuning and pa tower.
Tons of user adjustable macro variables for customization and further tuning.
Many small usability improvements and sanity checks.

Adaptive Meshing and Priming

Adaptive meshing and priming is now officially out of beta and enabled by default. Beacon adaptive priming and full IDEX support has been added.

User hooks are now supplied with the full params of the calling macro
ratos CLI tool for utility functions, advanced usage and third party integrations. Use it to regenerate configuration, flash connected boards, tail logs, register / unregister / symlink klippy and moonraker extensions and more.

Backwards compatibility

RatOS 2.0 configurations will still work in 2.1 (As for RC2 this is unknown.. will need testing)
Generating a new configuration will require that you reflash your toolboard via the configurator.

Huge shutout to @HelgeKeck for his tireless work, and @3dprintpt for all the new boards and wiring diagrams!
