+
+## ✨NEW: Hardware Version 4.0
+A new version of the hardware has been released, fixing several issues with the previous design:
+
+- Self collision during homing fixed.
+- Connection of ball joint block with screws only was not well constrained and could rotated a bit.
+- No reliable way to ensure consistent linkage rod length
+- Unnecessary ball joint friction
+- Accurate ball position heavily dependet on print quality and corner rounding
+- Rubber bands could not be changed or removed once glued in.
+
+A video about the improved ball joint and linkage manufactoring process can be found on YouTube: [Better Ball Joints for the Open Micro-Manipulator](https://www.youtube.com/watch?v=NM2KXvRGmpg)
+Also the FreeCAD model was restructured and improved and now includes all pins and fasteners. It now provides a reference for all required mechanical parts.

+## Open Micro-Manipulator GUI
 To make testing and using the Open-Micro Manipulator easy and convenient a python control program with a graphical user interface is provided here: [Open Micro-Manipulator GUI](https://github.com/0x23/OpenMicroManipulatorGUI).
 It has simple controlls to move the device around, while also displaying a live camera feed (e.g. from a microscope camera). Additional features, include a simple g-code runner and realtime mouse control (e.g. for Biology applications).

+## ✨ Firmware v1.0.4
 
-## ✨ Firmware v1.0.1
+Firmware 1.0.4 comes with many smaller improvements and bugfixes and a great new feature as well:
+
+ - **Tools**: Tool usage (for example for laser engraving) is now supported on the two GPIO pins of J5 on the pcb.
+              Tools are integrated into the planner and run fast and with correct timing when executing g-code.
+              The tools support PWM (using the PIO feature to squeeze out extra channels without relying on software PWM).
+
+   Example usage:
+   ```
+     M3 T0 S0.7  // set pwm output of tool 0 to 70%
+     G4 S0.001   // dwell command (or any other motion command) - necessary to apply the tools output
+   ```
+   
+- **Calibration**: Calibration has now some addition error checks to improve error reporting of potential problems like encoder alignment.
+- **Kinematic Model Parameter**: Initialization code has been cleaned up and better comments where added to the parameters. Parameters are preset for HW v4.0 but you can toggle back to the old HW-v3.0 parameters if necessary.
+- **Bugfixes**: smaller bugfixes
+
+IMPORTANT: If you have **Hardware Version v3.0** you need to switch back to the old kinematic parameters in the [kinematic_model_delta3d.cpp](firmware/MotionControllerRP/src/kinematic_models/kinematic_model_delta3d.cpp) file (there is an #define for that at the top).

+# Setup Guide
+
+This guide walks you through the setup of your new **Open Micro-Manipulator** device.
+
+## Checklist for New Devices
+
+1. **Was the mechanical limit pin added to the rotor?**  
+   This pin is required for proper homing of the device.
+
+    <div style="display: flex;">
+        <img src="mechanical_limit_pin.jpg" alt="Mechanical Limit Pin" width="40%">
+    </div>
+
+
+2. **Are the screws that secure the rotor to the motor shaft installed?**  
+   If the rotor is not firmly attached, it may slip imperceptibly during homing or other movements, leading to problems during calibration and homing.
+
+3. **Is the homing direction correct?**  
+   During the homing command (`G28`), the end effector should move toward the base.  
+   If it moves in the opposite direction, rewire the motor to reverse its direction.
+
+   <div style="display: flex;">
+       <img src="homing_direction.jpg" alt="Mechanical Limit Pin" width="40%">
+   </div>
+
+
+## Calibration and Checking the Encoders
+
+You can use the calibration plotter to check if your encoders are working as expected.
+On the left you see a good calibration on the right a bad calibration.
