+## Technology Stack
 
-- `/docs`: Documentation for the project.
+**Backend:** Rust with [Ethercrab](https://github.com/ethercrab-rs/ethercrab) for EtherCAT, [SocketIO](https://socket.io/) for real-time communication, [axum](https://docs.rs/axum/latest/axum/) for REST API
 
-# Technology Choices
+**Frontend:** [Electron](https://www.electronjs.org/) + [React](https://react.dev/) with [Shadcn](https://ui.shadcn.com/) components and [Tailwind](https://tailwindcss.com/) styling
 
-## Backend
 
-To interface with Beckhoff and other EtherCAT devices we need an EtherCAT master stoftware. Possibilities are [PySOEM](https://github.com/bnjmnp/pysoem) (Python), [SOEM](https://github.com/OpenEtherCATsociety/SOEM) (C) and [Ethercrab](https://github.com/ethercrab-rs/ethercrab) (Rust). For realtime operation only C and Rust are suitable. We chose Rust because of safety and confidence in the written code.
+## Hardware Examples
 
-[SocketIO](https://socket.io/) was chosen for performant event driven communication from the backend to the server. But we still use REST with [axum](https://docs.rs/axum/latest/axum/) for the communication thet benefits from the request/response model.
+QiTech Control supports a wide range of EtherCAT hardware from WAGO and Beckhoff. We provide complete step-by-step tutorials with wiring diagrams and software configuration for many common modules.
 
-We use [Smol](https://github.com/smol-rs/smol) for EtherCAT IO in the control loop for it's performance and [Tokio](https://tokio.rs/) for server IO because of it's ecosystem and maturity.

-We could combine the code of the frontend and backend using [Doxius](https://dioxuslabs.com/) but it lacks good Linux support. We chose [Electron](https://www.electronjs.org/) with [React](https://react.dev/) for it's maturity and ecosystem. For the UI we use [Shadcn](https://ui.shadcn.com/) components and [Tailwind](https://tailwindcss.com/) for styling. For routing we use [TanStack Router](https://tanstack.com/router/v1).
+## QiTech Machines
 
-# Dev Setup
+QiTech Control powers 10+ production machines for filament extrusion, winding, measurement, and material processing.
 
-[Developer Documentation](./docs/developer-docs/)
+**[View complete machine catalog on the wiki](https://github.com/qitechgmbh/control/wiki/QiTech-Machines)**
 
-## Backend
 
-- Rust stable 1.86^ toolchain (install via [rustup](https://rustup.rs/))
-- `rust-analyzer` extension for VSCode
-- Set your interface in `server/src/ethercat/init.rs` like `en10`
-- Connect a Beckhoff EK1100 to your interface
-- run `cd server && cargo run` to start the server (localhost:3001)
+## Contributing
 
-## Frontend
+This is an open-source project. Contributions are welcome! Please see the [wiki](https://github.com/qitechgmbh/control/wiki) for development guidelines.
 
-- nodejs and npm installed
-- run `cd electron && npm i && npm run start` to start the frontend

+# XTREM Communication Protocol
+
+**Version:** 3.007
+**Device:** XTREM / XTREM-S Weighing Module
+**Standard:** OIML R76:2006 / EN45501:2015 compliant
+
+---
+
+## Overview
+
+The **XTREM communication protocol** allows a terminal or host controller to exchange data and commands with the XTREM weighing module.
+The device transmits and receives ASCII-coded frames over a serial interface (RS232, RS485, Wi-Fi, or Ethernet, depending on configuration).
+
+Since we are using the Ethernet interface we need to provide some kind of DHCP to assign an IP - Address to each XTREM Device.
+They then may be addressed via a **broadcast** IP (e.g.: 192.168.4.255/24).
+A **Unicast** communication is applied through the device ID inside the XTREM Frame.
+
+---
+
+## Frame Structure
+
+Each message—both query and response—has the same format:
+
+```
+STX ID_O ID_D F D_ADDRESS D_L DATA LRC ETX
+```
+
+| Field         | Description                                       | Length (bytes) |
+| :------------ | :------------------------------------------------ | :------------: |
+| **STX**       | Start of message (ASCII `02h`)                    |        1       |
+| **ID_O**      | Sender address (2 ASCII hex chars)                |        2       |
+| **ID_D**      | Destination address (2 ASCII hex chars)           |        2       |
+| **F**         | Function code (`R`, `W`, `E`, etc.)               |        1       |
+| **D_ADDRESS** | Data address (register, 4 ASCII hex chars)        |        4       |
+| **D_L**       | Data length (2 ASCII hex chars)                   |        2       |
+| **DATA**      | Optional data field                               |    Variable    |
+| **LRC**       | Longitudinal Redundancy Check (2 ASCII hex chars) |        2       |
+| **ETX**       | End of message (ASCII `03h`)                      |        1       |
+
+In the default configuration the Frame also requires a CRLF at the end.
+
+**Example:**
+
+```
+STX ‘1’ ‘7’ ‘0’ ‘1’ ‘R’ ‘0’ ‘1’ ‘0’ ‘1’ ‘0’ ‘0’ LRC ETX CR LF
+```
+
+---
+
+## Function Codes
+
+| Function | ASCII | Hex | Description     |
+| :------- | :---- | :---| :-------------- |
+| **R**    | R     | 52h | Read request    |
+| **r**    | r     | 72h | Read response   |
+| **W**    | W     | 57h | Write request   |
+| **w**    | w     | 77h | Write response  |
+| **E**    | E     | 45h | Execute command |
+| **e**    | e     | 65h | Execute response|
+
+### Write response codes
+
+* `'0'` – OK
+* `'1'` – Write denied (sealed)
+* `'2'` – Read-only register
+* `'3'` – Invalid value / out of range
+
+### Execute response codes
+
+* `'0'` – Executed successfully
+* `'1'` – Blocked by seal switch
+
+---
+
+## LRC Calculation
+
+The **Longitudinal Redundancy Check** is a one-byte XOR of all message bytes, excluding:
+
+* `STX`
+* `ETX`
+* The LRC itself
+
+Example C function:
+
+```c
+unsigned char LRC(unsigned char* s) {
+    unsigned char lrc = 0;
+    while (*s) {
+        lrc ^= *(s++);
+    }
+    return lrc;
+}
+```
+
+Example Rust function:
+```rust
+pub fn compute_lrc(data: &[u8]) -> u8 {
+    data.iter().fold(0u8, |acc, &b| acc ^ b)
+}
+
+```
+
+---
+
+## Key Data Registers
+
+| Address (hex) | Description                | Type | Notes                                 |

+| **0007h**     | Hardware version           |   R  | Read-only                             |
+| **0008h**     | Software version           |   R  | Read-only                             |
+| **0009h**     | Sealing switch status      |   R  | `0=UNLOCK`, `1=LOCK`                  |

+| **0013h**     | Stream mode output rate    |  RW  | Time in ms                            |
+| **0100h**     | Device state               |   R  | Status bits (power, Wi-Fi, ADC, etc.) |
+| **0101h**     | Weight value               |   R  | Gross weight                          |
+| **0102h**     | Tare value                 |  RE  | Read/Execute                          |
+| **0103h**     | Net weight                 |   R  | Gross − Tare                          |
+| **0110h**     | ADC counts (instant)       |   R  | Raw ADC data                          |

+| **EEEEh**     | Factory reset              |   E  | Restores defaults                     |
+
+---
+
+## Post-Factory Reset Configuration
+
+After performing a factory reset, several registers must be configured to ensure proper operation of the device.
+
+Note: The unit may remain set to 'g' after a factory reset, but the values received may be in 'kg' depending on the device configuration.
+
+The following registers should be reviewed and set as required:
+1. **Address: 0022 | Max (Max1) (scale maximum capacity)**
+    The default value for this register may vary between devices (e.g., 60000 or 6000). Set this value to 6000 to ensure correct operation.
+2. **Address: 0023 | e (e1) (scale interval)**
+3. **Address: 0026 | Decimal position**

+## 1. Introduction
+
+The EL2004 LED Toggle Example is a minimal demonstration showing how to control digital outputs on a **Beckhoff EL2004 EtherCAT terminal** using the QiTech machine framework.  
+It represents the simplest possible hardware interaction in the system:  
+**toggling LED outputs using the QiTech Control Dashboard.**
+
+---
+
+## 2. Requirements
+
+### Hardware
+- Beckhoff **EL2004 EtherCAT Terminal** (4-channel digital output)  
+- Beckhoff **EK1100 EtherCAT Coupler**  
+- **24 V DC power supply** (AC/DC adapter + DC hollow plug)  
+- Jumper / bridge wires (0.5–1.5 mm² recommended)  
+- A **Linux PC** (Ubuntu/Debian recommended)  
+- Standard Ethernet cable  
+- Flat screwdriver  
+
+### Software  
+*(Installation steps in Section 4)*  
+- Rust toolchain  
+- Node.js + npm  
+- Git  
+- QiTech Control repository  
+- EtherCAT HAL (included inside repo)
+
+---
+
+## 3. Hardware Setup
+
+### 3.1 Schematic
+
+![](../assets/schematic.png)
+
+---
+
+### 3.2 EK1100 Wiring
+
+This wiring configuration powers the EL2004 and prepares it for LED control.  
+It is not the only possible wiring but is the **simplest functional setup**.
+
+#### ⚠️ Safety Warning  
+Always disconnect power before wiring.  
+Working on live EtherCAT terminals can cause serious damage or electrical shock.
+
+---
+
+#### 3.2.1 Safe Wiring Procedure (Beckhoff Recommended)
+
+1. Insert a screwdriver **straight** into the square release hole.  
+2. Insert the stripped wire into the round opening.  
+3. Remove the screwdriver — the spring clamp locks the wire.
+
+![](../assets/wiring.png)
+
+---
+
+#### 3.2.2 Wiring Steps (Used in This Example)
+
+We supply power using a **DC hollow-plug adapter**, like this one:  
+https://www.amazon.de/dp/B093FTFZ8Q
+
+Perform the following wiring on the EK1100:
+
+1. Red wire **(+24 V)** → Terminal **2**  
+2. Black wire **(0 V)** → Terminal **3**  
+3. Jumper wire from **Terminal 1 → Terminal 6**  
+4. Jumper wire from **Terminal 5 → Terminal 7**  
+
+After wiring, your module should look like **Figure 1**.
+
+---
+
+#### **Figure 1 — EK1100 Minimal Wiring**
+<img src="../assets/ek1100.jpeg" width="400">
+
+
+---
+
+### 3.3 EL2004 Integration
+
+Slide the EL2004 onto the **right side of the EK1100** until it locks.  
+The EtherCAT E-Bus and power contacts connect automatically — **no wiring required**.
+
+#### **Figure 2 — EL2004 Terminal**
+<img src="../assets/el2004.jpeg" width="400">
+
+---
+
+### 3.4 Final Assembled Setup
+
+#### **Figure 3 — EK1100 + EL2004 Connected**
+<img src="../assets/complete.jpeg" width="400">
+
+---
+
+### 3.5 Power & Ethernet
+
+#### Power  
+Connect the 24 V adapter to the hollow plug used earlier.
+**Example AC/DC Adapter (Figure 4):**
+
+<img src="../assets/adapter.jpeg" width="400">
+
+
+#### Ethernet  
+Use a standard LAN cable to connect your PC → EK1100.
+The final powered up and connected setup should look like this:
+
+<img src="../assets/power.jpeg" width="400">
+
+---
+
+## 4. Software Setup
+
+### 4.1 Installing on Ubuntu/Debian
+
+Paste this into your terminal:
+
+```bash
+# Press Enter when prompted
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+sudo apt update
+sudo apt install -y npm nodejs git
+
+git clone git@github.com:qitechgmbh/control.git
+cd control/electron
+npm install
+```
+### 4.2 Running the Backend
+```bash
+./cargo_run_linux.sh
+```
+This script:
+
+- Builds the backend
+
+- Grants required system capabilities (raw sockets)
+
+- Starts EtherCAT communication
+
+Ensure the EK1100 is connected.
+
+### 4.3 Running the Frontend
+```bash
+cd electron
+npm run start
+```
+This launches the QiTech Control dashboard.
+
+## 5. Demo
+
+### 5.1 Assigning Devices in the Dashboard
+
+Once the backend + frontend are running, you should see:
+
+- EK1100 Coupler
+
+- EL2004 Digital Output Terminal
+![](../assets/discovery.png)
+
+Steps:
+
+- Click Assign on the EK1100
+
+- Select TestMachine V1
+ 
+![](../assets/setmachine.png)
+
+
+- Enter a serial number (use the same for EK1100 + EL2004)
+
+![](../assets/serserial.png)
+
+- Click Write
+
+- Repeat for the EL2004
+
+### 5.2 Testing LED Control
+Navigate to:
+
+Machines → TestMachine
+![](../assets/machinedetected.png)
+You will see this interface:
+
+![](../assets/machinecontrol.png)
+
+**You can now toggle the four digital outputs of the EL2004.**

+Working on live EtherCAT terminals can cause serious damage or electrical shock.
+
+### 3.2.1 Safe Wiring Procedure (Beckhoff Recommended)
+
+1. Insert a screwdriver **straight** into the square release hole.  
+2. Insert the stripped wire into the round opening.  
+3. Remove the screwdriver — the spring clamp locks the wire.

+
+### 3.2.2 Wiring Steps (Used in This Example)
+
+We supply power using a **DC hollow-plug adapter**, like this one:  
+https://www.amazon.de/dp/B093FTFZ8Q
+
+Perform the following wiring on the EK1100:
+
+1. Red wire **(+24 V)** → Terminal **2**  
+2. Black wire **(0 V)** → Terminal **3**  
+3. Jumper wire from **Terminal 1 → Terminal 6**  
+4. Jumper wire from **Terminal 5 → Terminal 7**  
+
+After wiring, your module should look like **Figure 1**.

+
+### 3.3 EL3021 Integration
+
+Slide the EL3021 onto the **right side of the EK1100** until it locks.  
+The EtherCAT E-Bus and power contacts connect automatically.
+Then you need to wire the adjustable power supply to the EL3021.

+
+## 4. Software Setup
+
+### 4.1 Installing on Ubuntu/Debian
+
+Paste this into your terminal:
+
+```bash
+# Press Enter when prompted
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+sudo apt update
+sudo apt install -y npm nodejs git
+
+git clone git@github.com:qitechgmbh/control.git
+cd control/electron
+npm install
+```
+### 4.2 Running the Backend
+```bash
+./cargo_run_linux.sh
+```
+This script:
+
+- Builds the backend
+
+- Grants required system capabilities (raw sockets)
+
+- Starts EtherCAT communication
+
+Ensure the EK1100 is connected.
+
+### 4.3 Running the Frontend
+```bash
+cd electron
+npm run start
+```
+This launches the QiTech Control dashboard.
+
+## 5. Demo
+
+### 5.1 Assigning Devices in the Dashboard
+Once both backend and frontend are running, the Setup -> EtherCat page should look something like this:
+![](../assets/EL3021_overview.png)
+Listing the EK1100 and the EL3021.
+
+To assign the two devices to a machine, click "Assign" on both devices. This should open the following pop-up modal:
+
+**EK1100**
+![](../assets/EL3021_assign.png)
+1. Select "AnalogTest V1" under "Machine"
+2. Choose a serial number to uniquely identify the machine (1 in this example)
+3. Under "Device Role" select "0 - Bus Coupler"
+
+**EL3021**
+![](../assets/EL3021_assign2.png)
+1. Select "AnalogTest V1" under "Machine"
+2. Use the same serial number you chose for the EK1100
+3. Under "Device Role" select "1 - EL3021"
+---
+The machine is now configured.
+A new Tab "AnalogTest" should appear in the right sidebar. Clicking that tab should show the machine control interface:
+![](../assets/EL3021_control.png)
+Results should show the current measured by the analog input - the current set on the adjustable power supply.

+## 3. Hardware Setup
+
+### 3.2 EK1100 Wiring
+
+This wiring configuration powers the EL7031-0030.  
+It is not the only possible wiring but is the **simplest functional setup**.
+
+#### ⚠️ Safety Warning
+Always disconnect power before wiring.  
+Working on live EtherCAT terminals can cause serious damage or electrical shock.
+
+---
+
+#### 3.2.1 Safe Wiring Procedure (Beckhoff Recommended)
+
+1. Insert a screwdriver **straight** into the square release hole.
+2. Insert the stripped wire into the round opening.
+3. Remove the screwdriver — the spring clamp locks the wire.

+
+Perform the following wiring on the EK1100:
+
+1. Red wire **(+24 V)** → Terminal **2**
+2. Black wire **(0 V)** → Terminal **3**
+3. Jumper wire from **Terminal 1 → Terminal 6**
+4. Jumper wire from **Terminal 5 → Terminal 7**
+
+After wiring, your module should look like **Figure 1**.

+
+#### **Figure 2 — EL7031-0030 Terminal**
+
+<img src="../assets/EL7031_0030.jpg" width="300">
+
+Slide the EL7031-0030 onto the right side of the EK1100 until it locks.
+The EtherCAT E-Bus and power contacts connect automatically — **no wiring required**.

+
+That's what the pin should look like.
+
+---
+
+### 3.2.2 Wiring (EL7031-0030)
+
+**Crucial:** The EL7031 requires two power sources: E-Bus (side contacts) for logic, and Front Terminal (6 & 14) for motor power.
+
+| Terminal Point | Function         | Cable Color (Example) |
+| :------------- | :--------------- | :-------------------- |
+| **4**          | Motor Coil A1    | Red                   |
+| **12**         | Motor Coil A2    | Blue                  |
+| **5**          | Motor Coil B1    | Green                 |
+| **13**         | Motor Coil B2    | Black                 |
+| **6**          | **Power +24V**   | PSU Red (+)           |
+| **14**         | **Power 0V/GND** | PSU Black (-)         |
+
+---
+
+### 3.3 ⚠️ Safety Warning
+
+- **Mandatory Power Supply:** Without 24V connected to **Pin 6 (+24V)** and **Pin 14 (GND)**, the terminal will remain in `PREOP` state or show a "Warning" LED (No Power). The motor will **not** move without this external supply.
+
+#### Risk of Destruction (Short Circuit):
+- **Never** connect the 24V Power Supply to the Motor Output pins (**4, 5, 12, 13**). This will instantly destroy the terminal (causing pins 12 & 13 to glow red/burn).
+- Ensure strict separation: **Pins 4/5/12/13 are for the MOTOR ONLY**.
+- **Pins 6/14 are for POWER ONLY**.
+
+Also, see the documentation of the EtherCAT terminal ([EL7031-0030](https://download.beckhoff.com/download/document/io/ethercat-terminals/el7031-0030de.pdf)) for the different power modes (page 46 ff.)
+
+---
+
+## 4. Software Setup
+
+### 4.1 Installing on Linux (this depends on your distro)
+
+Paste this into your terminal:
+
+```bash
+# Press Enter when prompted
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+sudo apt update
+sudo apt install -y npm nodejs git
+
+git clone git@github.com:qitechgmbh/control.git
+cd control/electron
+npm install
+```
+
+### 4.2 Running the Backend
+
+```bash
+./cargo_run_linux.sh
+```
+
+This script:
+- Builds the backend
+- Grants required system capabilities (raw sockets)
+- Starts EtherCAT communication
+
+### 4.3 Running the Frontend
+
+```bash
+# move to the control directory
+cd electron
+npm run start
+```
+
+This launches the QiTech Control dashboard.
+
+---
+
+## 5. Demo
+
+### 5.1 Assigning Devices in the Dashboard
+
+Once the backend + frontend are running, you should see:
+
+![](../assets/UI_start_motor.png)
+
+Make sure that under "Assign" → "Machine Assignment"
+the correct serial number is selected (each device should have the same one, here it is 1).
+Under "Machine" select your new Machine however you named it (I named it "TestMotor V1"), else it will detect that there is something connected to it but the connection won't work.
+
+![](../assets/machine_assigment_motor.png)
+
+**NOW THE MOTOR SHOULD TURN!**
+
+In the interface "TestMotor" on the left side, you can now control the motor (its state and its speed).
+
+![](../assets/UI_motor.png)

+
+## 6. Documentation
+
+Use the official documentation of the EL7031-0030 for more information:  
+[Beckhoff EL7031-0030 Documentation](https://download.beckhoff.com/download/document/io/ethercat-terminals/el7031-0030de.pdf)
+
+---
+
+## 7. Software Architecture
+
+### Backend (Rust)
+Located in [machines/src/motor_test_machine/](/machines/src/motor_test_machine/).
+
+1. **`mod.rs`**: Defines the `MotorTestMachine` struct and holds the state (driver wrapper, enabled state, target velocity).
+2. **`api.rs`**: Handles incoming JSON commands from the frontend (Enable/Disable, Set Velocity) via WebSockets/SocketIO.
+3. **`act.rs`**: The real-time control loop. It updates the `StepperVelocityEL70x1` driver wrapper in every cycle based on the current state.
+4. **`new.rs`**: Initializes the hardware.
+
+### Frontend (TypeScript/React)
+Located in [electron/src/machines/motor_test_machine/](/electron/src/machines/motor_test_machine/) and [electron/src/routes/routes.tsx](/electron/src/routes/routes.tsx).
+
+1. **`useTestMotor.ts`**: Custom hook managing the optimistic state and communication with the backend.
+2. **`TestMotorControlPage.tsx`**: The UI using QiTech UI components (`ControlCard`, `EditValue`, `SelectionGroupBoolean`) to match the look and feel of the Winder2.
+3. **Routing**: Integrated into `routes.tsx` using TanStack Router, ensuring the machine appears in the sidebar and navigation works correctly.
