+# 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
+
+![](./docs/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.
+
+![](./docs/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**.
+
+---
+

+
+
+---
+
+## 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**.

+
+# 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
+![](./docs/assets/discovery.png)
+
+Steps:
+
+- Click Assign on the EK1100
+
+- Select TestMachine V1
+ 
+![](./docs/assets/setmachine.png)
+
+
+- Enter a serial number (use the same for EK1100 + EL2004)
+
+![](./docs/assets/serserial.png)
+
+- Click Write
+
+- Repeat for the EL2004
+
+## 5.2 Testing LED Control
+Navigate to:
+
+Machines → TestMachine
+![](./docs/assets/machinedetected.png)
+You will see this interface:
+
+![](./docs/assets/machinecontrol.png)
+
+**You can now toggle the four digital outputs of the EL2004.**

+![](./docs/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**
+![](./docs/assets/EL3021_assign.png)
+1. Select "AnalogTest V1" under "Maschine"
+2. Choose a serial number to uniquely identify the machine (1 in this example)
+3. Under "Device Role" select "0 - Bus Coupler"
+
+**EL3021**
+![](./docs/assets/EL3021_assign2.png)
+1. Select "AnalogTest V1" under "Maschine"
+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:
+![](./docs/assets/EL3021_control.png)
+Results should show the current measured by the analog input - the current set on the adjustable power supply.

+//! # Circular Converter
+//!
+//! This module provides the `CircularConverter` which handles transformations between
+//! linear and angular measurements for circular motion systems.
+//!
+//! ## Usage
+//!
+//! The `CircularConverter` is designed to work alongside other converters:
+//! - Use `AngularStepConverter` for angular-to-step conversions
+//! - Use `LinearStepConverter` for complete linear-to-step conversions (uses `CircularConverter` internally)
+//! - Use `CircularConverter` directly when you need linear-to-angular conversions without steps
+//!
+//! ## Examples
+//!
+//! ```rust
+//! use control_core::converters::circular_converter::CircularConverter;
+//! use units::{f64::{Length, Velocity}, length::meter, velocity::meter_per_second};
+//!
+//! let converter = CircularConverter::from_radius(Length::new::<meter>(0.1));
+//! let velocity = Velocity::new::<meter_per_second>(1.0);
+//! let angular_velocity = converter.linear_to_angular_velocity(velocity);
+//! ```

+# How can I add a new Machine?
+
+Adding a new machine follows a common structure in `server/machines/`.
+
+
+
+# TLDR
+
+Summary
+
+When adding a new machine:
+
+- Create Folder server/machines/YOUR_MACHINE_NAME/.
+- Add the 4 files (mod.rs, new.rs, act.rs, api.rs).
+- Register it in machines/mod.rs with a unique constant.
+- mod.rs: define the struct + emit functions.
+- new.rs: assemble devices/controllers into the machine.
+- act.rs: implement the machine loop (MachineAct).
+- api.rs: define request (mutations) and response (events) types.
+
+Tip: Start simple (copy MockMachine) and grow complexity as needed (add EtherCAT devices, controllers, etc.).
+
+---
+
+## 1. Create the folder
+
+Create a new directory:
+server/machines/YOUR_MACHINE_NAME
+
+At a minimum, this folder needs the following files:
+
+- `mod.rs`
+- `new.rs`
+- `act.rs`
+- `api.rs`
+
+---
+
+## 2. Register the module
+
+Add your machine to `server/machines/mod.rs`:
+
+```rust
+// mod.rs
+pub mod buffer1;
+pub mod extruder1;
+pub mod laser;
+pub mod mock;
+pub mod registry;
+pub mod winder2;
+pub mod YOUR_MACHINE;
+
+pub const VENDOR_QITECH: u16 = 0x0001;
+pub const MACHINE_WINDER_V1: u16 = 0x0002;
+pub const MACHINE_EXTRUDER_V1: u16 = 0x0004;
+pub const MACHINE_LASER_V1: u16 = 0x0006;
+pub const MACHINE_MOCK: u16 = 0x0007;
+pub const MACHINE_BUFFER_V1: u16 = 0x0008;
+pub const YOUR_MACHINE_V1: u16 = 0xffff; // pick a unique ID to avoid collisions also DO NOT touch any already defined ids!!
+```
+
+## 3. mod.rs
+
+This file defines your machine struct and the required event emitters.
+
+Look at MockMachine’s mod.rs for the simplest possible version.
+
+At a minimum, you need:
+- emit_state
+- emit_live_values
+- A machine struct for state(e.g. MockMachine, Extruder, Laser, Winder, …)
+
+More complex machines (e.g. Extruder, Winder) encapsulate controllers that in turn manage devices like EtherCAT terminals.
+
+## 4 new.rs
+
+This file implements MachineNewTrait for your machine.
+Here you assemble your machine from its parts — devices, controllers, and any state.
+
+Minimal example: see MockMachine → basically no devices, just returns a struct.
+
+Medium complexity: see Laser → wraps a single serial USB device.
+
+High complexity: see Extruder → configures multiple EtherCAT devices inside controllers.
+
+Think of new.rs as the factory:
+This is the place to declare which devices make up your machine and how they’re configured.
+
+## 5. act.rs
+
+This file implements the machine control loop using MachineAct.
+The act() method is called repeatedly by the control runtime.
+
+```rs
+impl MachineAct for YourMachine {
+    fn act(&mut self, _now_ts: Instant) -> Pin<Box<dyn Future<Output = ()> + Send + '_>> {
+        Box::pin(async move {
+            let now = Instant::now();
+
+            // Update state, e.g. step a controller
+            self.some_controller.update();
+
+            // Emit live values ~30 Hz if machine is in Running mode
+            if now.duration_since(self.last_measurement_emit) > Duration::from_secs_f64(1.0 / 30.0) {
+                self.maybe_emit_state_event();
+                self.emit_live_values();
+                self.last_measurement_emit = now;
+            }
+        })
+    }
+}
+```
+
+## 6. api.rs
+
+Defines the frontend-facing API for your machine:
+
+Mutations → requests that the machine accepts
+(e.g. start/stop commands, setpoints, configuration updates).
+
+Events → responses emitted to the frontend
+(e.g. live sensor data, alarms, machine state changes).
+
+Look at MockMachine’s api.rs for a minimal version.
+
+```rs
+/// Mutations are API requests to control the machine
+#[derive(Debug, Clone, serde::Deserialize)]
+#[serde(tag = "type", rename_all = "snake_case")]
+pub enum YourMachineMutation {
+    Start,
+    Stop,
+    SetSpeed { rpm: f64 },
+}
+
+/// Events are responses sent to the frontend
+#[derive(Debug, Clone, serde::Serialize)]
+#[serde(tag = "type", rename_all = "snake_case")]
+pub enum YourMachineEvent {
+    StateChanged { state: String },
+    LiveValues { rpm: f64, torque: f64 },
+}
+
+```

+# Code Style
+
+# General Code styling
+
+Try to adhere to the rust style guide:
+https://doc.rust-lang.org/nightly/style-guide/
+
+# Beckhoff terminals and Machines
+
+For Beckhoff terminals you should first implement the basic functionality, then an Interpreter of the device/data is built on top.
+A good example of how to do this is by looking at the following code:
+el3021.rs , AnalogInputDevice
+
+El3021 implements a so called AnalogInputDevice, which acts like an interface.
+This allows us to use AnalogInputDevice instead of having to always specify which device should be used.
+In Essence any Device that implements AnalogInputDevice can be used.
+
+AnalogInputDevice is then used for creating an AnalogInput, which is plug and play for machines.
+
+Then a further layer of Abstraction is used on top,
+where the data is interpreted and incorporated into a sort of control loop for certain functions, for example:
+
+```rust
+// ScrewSpeedController controlls the speed (frequency) and direction of the motor
+// AnalogInput is used to collect measurements from the pressure sensor.
+// screw_speed_controller.rs
+#[derive(Debug)]
+pub struct ScrewSpeedController {
+    pub pid: ClampingTimeagnosticPidController,
+    pub target_pressure: Pressure,
+    pub target_rpm: AngularVelocity,
+    pub inverter: MitsubishiCS80,
+    pressure_sensor: AnalogInput,
+    last_update: Instant,
+    uses_rpm: bool,
+    forward_rotation: bool,
+    transmission_converter: TransmissionConverter,
+    frequency: Frequency,
+    maximum_frequency: Frequency,
+    minimum_frequency: Frequency,
+    motor_on: bool,
+    nozzle_pressure_limit: Pressure,
+    nozzle_pressure_limit_enabled: bool,
+}
+
+// Under the hood for ExtruderV2 a El3021 is used:
+// (from new.rs of extruder)
+let pressure_sensor = AnalogInput::new(el3021, EL3021Port::AI1);
+
+// But the extruder does not directly use the AnalogInput, instead the logic is decoupled in the screw_speed_controller:
+let mut extruder: ExtruderV2 = Self {
+    namespace: ExtruderV2Namespace::new(params.socket_queue_tx.clone()),
+    last_measurement_emit: Instant::now(),
+    mode: ExtruderV2Mode::Standby,
+    temperature_controller_front: temperature_controller_front,
+    temperature_controller_middle: temperature_controller_middle,
+    temperature_controller_back: temperature_controller_back,
+    temperature_controller_nozzle: temperature_controller_nozzle,
+    screw_speed_controller: screw_speed_controller,
+    emitted_default_state: false,
+};
+
+// Then in act.rs
+// The extruder simply calls the update function of the screw_speed_controller,
+// which contains "all" of the logic needed to properly drive the motor
+self.screw_speed_controller.update(now_ts, true);
+
+
+```
+
+This is desired behaviour for all implemented devices, the machines should stay as modular as possible.
+
+# Representing physical Units (Volt,Ampere,Hz,RPM etc)
+
+To represent physical units like voltage ampere etc... we use uom (units of measurement), which acts as a wrapper for units and supplies all conversions between certain units.
+For example:
+
+```rust
+// Lets say a device measures voltage, you just got the raw value
+let volts : ElectricPotential = ElectricPotential::new::<volt>(raw_value_here);
+// Then you can do this to get milli_volts
+// In api responses we always use the RAW float value (64bit):
+let milli_volts : f64 = volts.get::<millivolt>();
+```
+
+# General Advice
+
+- Try to avoid duplicate code (DRY principle)
+- Try to avoid lifetimes if at all possible
+- Avoid excessive abstractions
+- Avoid async code unless it is required
+- Avoid taking Ownership of values, instead borrow the value
+- When implementing a Trait for a struct, do it in the same file as the struct definition
+- Split up large impl blocks into smaller impl blocks

+# Environment Setup
+
+Working on this repository requires you to use cargo and npm. In the following document the installation process will be shown
+
+## Ubuntu/Debian Installation
+
+```bash
+    # Just press enter when prompted
+    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+    apt install npm
+    apt install nodejs
+    # assuming you dont have git already, Git setup not included in here

+
+# Running Backend and Frontend Linux
+
+## Backend
+
+To Compile backend code and run it on Linux:
+
+```bash
+./cargo_run_linux.sh
+```
+
+The script sets capabilities on the compiled binary like raw socket access.
+Here it is required that you are connected to atleast one machine that is communicated with over ethercat or usb/serial.
+The Most minimal working setup would be to connect over ethernet to an ek1100 beckhoff terminal.
+
+## Mock-Machine
+
+The Mock-Machine can be used to test code that does not require an actual machine connection.
+Like Frontend Code for example.
+
+Mock machines can be used if the compile feature mock-machine is enabled.
+
+```bash
+# in root git folder
+./cargo_run_linux.sh mock-machine
+```
+
+## Frontend
+
+To run the Frontend Code:
+
+```bash
+# need to be in the electron folder and an additional terminal
+cd electron
+npm run start
+```
+

+# Performance/Stability Tweaks 
+## EtherCrab Config
+We set ethercrab to default settings for everything except for RetryBehaviour, so that one unlikely failure doesnt destroy the EtherCAT network.
+
+```rust
+    let maindevice = MainDevice::new(
+        pdu,
+        Timeouts {
+            // Default 5000ms

+            dc_static_sync_iterations: 10_000,
+        },
+    );
+
+```
+wait_loop_delay CAN in theory also decrease CPU usage if set exactly as the loop_delay we set, however this setting has caused us some issues, so we just leave it as is.
+
+## Realtime Kernel
+In our nixOs Config we use the latest realtime kernel and isolate TWO cores out of the Four available for the machines we use.
+
+```nix
+ #From configuration.nix
+ boot.loader.efi.canTouchEfiVariables = true;
+ boot.kernelPackages = pkgs.linuxPackages-rt_latest;
+ boot.kernelModules = [ "i915" ];
+```
+
+Notice how we hardcode the intel gpu kernel module. This is because only the GPU driver gets blacklisted for some reason. By specifying it manually it loads like before.
+
+One Core is used for the EtherCrab TXRX Thread and one is used for the machine Thread. 
+```
+    "isolcpus=2,3" # Isolate cpus 2 and 3 from scheduler for better latency, 2 runs ethercatthread and 3 runs server control-loop
+    "nohz_full=2,3" # In this mode, the periodic scheduler tick is stopped when only one task is running, reducing kernel interruptions on those CPUs.
+    "rcu_nocbs=2,3" # Moves RCU (Read-Copy Update) callback processing away from CPUs 2 and 3.
+```
+
+Essentially we completely disable acces from the operating system to these two cpus, which saves scheduler overhead, which would introduce noticable latency.
+Its not entirely clear yet if what we did here is overkill. Maybe we could use only one core and get away with that?
+Processor load normally hovers around 18% for one of the cores and like 9% for the other.
+
+We also have some minor cpu tweaks in configuration.nix
+```
+    # Graphical
+    "logo.nologo" # Remove kernel logo during boot
+
+    # Performance
+
+    # Specific Vulnerabilities Addressed by Mitigations:
+    # - Spectre variants (V1, V2, V4, SWAPGS, SpectreRSB, etc.)
+    # - Meltdown (Rogue Data Cache Load)

+    # - And others as they're discovered and mitigated
+    #
+    # With mitigations=off
+    # - PROS: Maximum performance, equivalent to pre-2018 behavior
+    # - CONS: Vulnerable to Spectre, Meltdown, Foreshadow, ZombieLoad, etc.
+    #         Should ONLY be used in completely trusted environments
+    # - Improves performance by 7-43%
+    "mitigation=off"
+    "intel_pstate=performance"    # Intel CPU-specific performance mode (if applicable)
+
+    # Memory Management
+    "transparent_hugepage=always" # Use larger memory pages for memory intense applications
+    "nmi_watchdog=0"              # Disable NMI watchdog for reduced CPU overhead and realtime execution
+
+    # High-throughput ethernet parameters
+    "pcie_aspm=off"         # Disable PCIe power management for NICs
+    "intel_iommu=off"       # Disable IOMMU (performance gain)
+
+    # Reliability
+    "panic=10"              # Auto-reboot 10 seconds after kernel panic
+    "oops=panic"            # Treat kernel oops as panic for auto-recovery
+    "usbcore.autosuspend=-1"     # Possibly fixes dre disconnect issue?
+```
+
+We should check if its really required to turn mitigations off as well.
+
+## Rust Code Optimizations
+
+In General we try to avoid memory allocations in our loop as much as possible, as it is not deterministic
+
+One problem we found, is that due to the realtime kernel our ethernet driver caused us quite large spikes in our tx_rx cycle time for EtherCAT.
+These spikes happen when CPU Load is very high on the two usable cores, causing the interrupt handler for Ethernet to stall.
+
+Which is why we reassign the interrupt handler on startup to the same core that the EtherCatTxRx Thread runs on:
+
+```rust
+#[cfg(target_os = "linux")]
+match set_irq_affinity(&interface, 3) {
+      Ok(_) => tracing::info!("ethernet interrupt handler now runs on cpu:{}", 3),
+      Err(e) => tracing::error!("set_irq_affinity failed: {:?}", e),
+}
+// Set core affinity to 4th core
+let _ = set_core_affinity(3);
+
+// Set the thread to real-time priority
+let _ = set_realtime_priority();
+```
+This means that the Interrupt Handler ALWAYS has enough ressources to cope with our demand for realtime communication with EtherCAT
+
+
+One Problem we have at the moment (we think) is the locking and async code blocking our server loop. 
+Note that this doesnt affect the EtherCAT communication at all.
+
+## Electron Optimizations (Not Yet Implemented)
+
+Currently we are struggling with the fact, that apparently Electron doesnt really have good support for HW acceleration on Linux.
+Electron runs with the software-renderer, which is VERY slow compared to a gpu. 
+This would eliminate the weird stuttering seen on Graphs and make them run buttery smooth, while also alleviating load off of the CPU.

+# Presets
+
+To allow the user to save the current configuration of a machine, they can create a preset in the presets page. Presets are presited in electron's local storage.
+
+Presets are all handled by the `PresetsPage`. To use the `PresetsPage` for a single machine, one must implement the following.
+
+Create a zod schema for the data, the presets contain.
+ ```tsx
+const mock1PresetDataSchema = z
+  .object({
+    frequency1: z.number(),
+    frequency2: z.number(),
+    frequency3: z.number(),
+  })
+  .partial();
+
+type Mock1 = typeof mock1PresetDataSchema;
+```
+Here, intensionally, `Mock1` is the schema type itself. It can be used as a type argument everything that uses presets.
+
+Next, create a map containing all schema versions currently supported (the new schema, to be precise).
+```tsx
+const schemas = new Map([[1, mock1PresetDataSchema]]);
+```
+New, the schema will be used to parse version `1`. To create new versions, see migrations below.
+
+One also needs to define a table, how the preset data should be shown to the user.
+```tsx
+const previewEntries: PresetPreviewEntries<Mock1> = [
+  {
+    name: "Frequency 1",
+    unit: "mHz",
+    renderValue: (data: PresetData<Mock1>) => data?.frequency1?.toFixed(3),
+  },
+  {
+    name: "Frequency 2",
+    unit: "mHz",
+    renderValue: (data: PresetData<Mock1>) => data?.frequency2?.toFixed(3),
+  },
+  {
+    name: "Frequency 3",
+    unit: "mHz",
+    renderValue: (data: PresetData<Mock1>) => data?.frequency3?.toFixed(3),
+  },
+];
+```
+`renderValue` gets the data itself and renders the corresponding part of it. Returning undefined will automatically be rendered as the value is not set, showing "N/A".
+
+Create a function for the new react component and use the appropreate machine.
+```tsx
+export function Mock1PresetsPage() {
+  const { setFrequency1, setFrequency2, setFrequency3, defaultState, state } =
+    useMock1();
+  // ...
+}
+```
+
+Here, two more functions need to be created.     const toPresetData = (s: typeof state): PresetData<Mock1> => ({
+    frequency1: s?.frequency1 ?? defaultState?.frequency1,
+    frequency2: s?.frequency2 ?? defaultState?.frequency2,
+    frequency3: s?.frequency3 ?? defaultState?.frequency3,The first takes in a preset and applies it on the machine. If data is missing, use the default defined by the backend.
+```tsx
+export function Mock1PresetsPage() {
+  const { setFrequency1, setFrequency2, setFrequency3, defaultState, state } =
+    useMock1();
+
+  const applyPreset = (preset: Preset<Mock1>) => {
+    const frequency1 = preset.data?.frequency1 ?? 100;
+    const frequency2 = preset.data?.frequency2 ?? 200;
+    const frequency3 = preset.data?.frequency3 ?? 500;
+
+    setFrequency1(frequency1);
+    setFrequency2(frequency2);
+    setFrequency3(frequency3);
+  };
+  // ...
+}
+```
+The later does the opposite, it turns a machine state, comming from the backend, into the preset data
+```tsx
+export function Mock1PresetsPage() {
+  const { setFrequency1, setFrequency2, setFrequency3, defaultState, state } =
+    useMock1();
+  // ...
+    const toPresetData = (s: typeof state): PresetData<Mock1> => ({
+    frequency1: s?.frequency1 ?? defaultState?.frequency1,
+    frequency2: s?.frequency2 ?? defaultState?.frequency2,
+    frequency3: s?.frequency3 ?? defaultState?.frequency3,
+  });
+  // ...
+}
+```
+
+Having all this, we can simple pass it to the `PresetsPage`
+```tsx
+export function Mock1PresetsPage() {
+  // ...
+  return (
+    <PresetsPage
+      machine_identification={mock1.machine_identification}
+      currentState={toPresetData(state)}
+      schemas={schemas}
+      schemaVersion={1}
+      applyPreset={applyPreset}
+      previewEntries={previewEntries}
+      defaultState={toPresetData(defaultState)}
+    />
+  );
+}
+```
+Also mind the machine identification, that has to match the machine we are using and the schema versionen. Here we pass `1`, as we also used `1` in the schemas map.
+
+## Migrations
+
+Migrations are handled by the `PresetsPage`, however, one still has to define what to migrate.
+To do so, first create the new schema.
+```tsx
+const fancyNewMock1PresetDataSchema = z
+  .object({
+    frequency1_now_with_ai: z.number(),
+    frequency2: z.number(),
+    frequency3: z.number(),
+    frequency4: z.number(),
+  })
+  .partial();
+
+type Mock1 = typeof fancyNewMock1PresetDataSchema;
+```
+and then, also create a migration that uses the new schema, but can handle the old format.
+```tsx
+const mock1PresetDataSchemaMigration: PresetSchema = z.preprocess(
+  (obj: any): PresetData<Mock1> => ({
+    frequency1_now_with_ai: obj?.frequency1, // Here, a field have been renamed
+    frequency2: obj?.frequency2,
+    frequency3: obj?.frequency3,
+    frequency4: 666.0, // A new field is added. Initialize it with default the value 
+  }),
+  fancyNewMock1PresetDataSchema,
+);
+```
+Usings zods preprocessing step,
+we can first transform the data as needed and then validate using the new schema accordingly.
+
+We have to register both schemas in our schema map.
+```tsx
+const schemas = new Map<number, Mock1>([
+  [1, mock1PresetDataSchemaMigration as Mock1],
+  [2, fancyNewMock1PresetDataSchema],
+]);
+```
+Mind the cast, which is ok, because `mock1PresetDataSchemaMigration` parses `fancyNewMock1PresetDataSchema` by construction.
+
+Lastly, simply change the schema version being passed to the `PresetsPage`.
+```diff
+@@ -62,7 +77,7 @@ export function Mock1PresetsPage() {
+       machine_identification={mock1.machine_identification}

+Make sure, that all (exsiting and new migrations) return a schema version 2 conform format.

+# Testing Ram and Cpu (Hardware)
+
+There were instability problems on one of the hmi panel pc's related to ram.
+
+To test Ram and Cpu for stability problems we use memtest86.
+
+You can download it here: https://www.memtest86.com/download.htm
+Then in the unzipped folder you have to flash the .img file to a USB drive with atleast 2GB of space.
+We already have USB-Sticks flashed with memtest though.
+
+1. When starting up the Pc mash Del (Entf in german) on an external keyboard and enter the bios
+
+2. Select the Memtest86 usb stick in the Bios
+
+3. Save changes and exit
+
+4. Now memtest boots up, just let it do its thing from here
+
+It works if the screen looks something like this:
+
+![](../assets/Memtest86_v83p.png)
+
+Simply let it do one Pass ~20 minutes and shutdown and unplug usb stick afterwards
+
+If it freezes completely -> unstable
+
+If it shows errors the ram should be swapped out and the test repeated
