 This project contains an open source low-cost, easy-to-build motorized **XYZ Micro-Manipulator** motion control platform achieving submicron precision.
 It's designed for applications such as optical alignment, probing electronic components, and microscopy.

 The device can be controlled via simple G-Code commands over a USB serial interface and is thus easily integrated into other projects.
 The firmware implements a complete motion planning stack with look-ahead for smooth and accurate path following capabilities.

+## ✨ NEW: Firmware v1.0.1
+
+This update improves calibration, homing, logging, and adds a Python API plus new G-Code commands.
+
+### Improvements
+- **Homing**: parallel homing support, higher repeatability, more accurate geometric reference  
+- **Joint calibration**: refined procedure, persistent flash storage (no recalibration after reboot)  
+- **Logging**: clearer and more detailed output  
+- **Python API**: easy device control from Python  
+
+### G-Code Commands
+- `G28` — Home joints (supports homing multiple axis simultanously for faster startup)
+- `G24` — Set pose command (directly sets servo targets, bypassing motion controller)  
+- `M17/M18` — Enable/Disable motors (with pose recovery from encoders on enable)  
+- `M51` — Read encoder values  
+- `M55` — Set servo loop parameters 
+- `M56` — Joint calibration (with save-to-flash option)  
+- `M57` — Read various information about the device state  
+- `M58` — Read firmware version

 The kinematic model is defined here: [kinematic_model_delta3d.cpp](firmware/MotionControllerRP/src/kinemtaic_models/kinematic_model_delta3d.cpp).
 Please check the dimensions of your build against the values set in the constructor. In particular, make sure the arm length matches.

 The firmware is written in C++ and takes some inspiration from the 'SimpleFOC' project. It aims to be streamlined and readable without any extra fuss, focusing on the hardware used in this project.
 It implements path planning with look-ahead and, unlike many other motion controller projects, supports true 6DOF-Pose interpolation and planning, making it ready for driving hexapod motion platforms; that may or may not be the next step for this project.

+### Building and Flashing the Firmware
 
 For building and flashing the firmware, Visual Studio Code (available for free on Windows and Linux) is recommended.
 Install the PlatformIO add-on and open the firmware folder. You can now build and flash the firmware like any other PlatformIO project.
