+//! # 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 uom::si::{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
+```
+
+# Contributing
+
+Generally you contribute to the codebase by:
+
+1. Opening or Choosing an existing issue (Bug,Feature,Task etc)
+2. Work on it locally
+3. Commit your changes locally
+4. Before pushing changes, if there were changes on the master branch, rebase your branch like so:

+# 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
+            state_transition: Duration::from_millis(5000),

+            pdu: Duration::from_micros(30_000),
+            // Default 10ms
+            eeprom: Duration::from_millis(10),
+            // Default 0ms
+            wait_loop_delay: Duration::from_millis(0),
+            // Default 100ms
+            mailbox_echo: Duration::from_millis(100),
+            // Default 1000ms

+            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)
+    # - Foreshadow/L1TF (L1 Terminal Fault)
+    # - Microarchitectural Data Sampling (MDS, RIDL, Fallout, ZombieLoad)
+    # - SRBDS (Special Register Buffer Data Sampling)
+    # - TSX Asynchronous Abort (TAA)
+    # - iTLB Multihit
+    # - 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}
+       currentState={toPresetData(state)}

+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

+# Device Implementation Guide
+
+This section describes how to implement EtherCAT devices in the framework used by the QiTech Control project (via `ethercat-hal`, `server`, etc.). We include a running example of a simple digital output device (EL2004) and discuss how it fits into the larger architecture.
+
+## Architecture & Context
+
+The QiTech Control system is built as:
+
+- `ethercat-hal` / `ethercat-hal-derive`: Hardware abstraction, PDO / CoE handling, device traits.  
+- `server`: Glue code that reads device identities, instantiates the correct device types, performs CoE configuration, and runs cyclic process data.  
+- The `docs` directory documents APIs and device patterns.  
+  :contentReference[oaicite:0]{index=0}  
+
+In this architecture:
+
+1. During initialization, subdevice identity tuples (Vendor ID, Product ID, Revision) are read.
+2. The `server` matches identity tuples to concrete `Device` types and constructs them (via `NewEthercatDevice`).
+3. The device instance then handles PDO exchange, and optional CoE (configuration) writes.
+4. Higher-level application code interacts with devices via traits like `DigitalOutputDevice`, `DigitalInputDevice`, etc.
+
+---
+
+## Example: Simple Digital Output Device (EL2004)
+
+Below is a minimal example of a digital-output-only EtherCAT device. It shows how to map PDOs, implement traits, and define identity constants.

+# Ethercat Tab shows no Ethercat Terminals!
+
+When the Ethercat page does not show any terminals, this can be due to multiple reasons
+
+## 1: Incorrect Connection of EK1100
+
+Check that the computers ethernet cable is properly connected to the EK1100 IN port
+
+Check the cabling if more than one EK1100 is used.
+When you have multiple EK the connection should be like this:
+
+Master (Your pc) -> Ethernet cable -> IN EK1100 (A)
+
+OUT EK1100 (A) -> Ethernet cable -> IN EK1100 (B)
+
+If you connected any part of this incorrectly the ethercat software will try to communicate but will fail, because the protocol works only if all devices are connect in series.
+
+## 2: Defective EtherCAT Terminal
+
+If a Terminal is somehow defective it can disrupt the communication flow expected by EtherCAT thus causing no devices to show up, as ethercat requires all terminals to work properly.
+
+To identify the defective terminal start unplugging terminals starting from the End terminal. Working your way backwards. Every time you unplug a terminal restart the backend process.
+
+You know that you have removed the defective terminal when the ethercat tab shows devices after your restart.
+
+Replace that terminal with an appropriate one and repeat this if the error persists.
+
+## 3: Corrupt Firmware on EtherCAT Terminal
+
+Another reason, that an Ethercat Terminal doesnt work properly, is that the firmware is corrupt. This could happen due to overvoltage,undervoltage or shorts, in some cases this is recoverable by reflashing the firmware.
+
+Our repository contains dumps for all of the EtherCAT Terminals, that we have used. To upload the firmware you can follow this guide: https://infosys.beckhoff.com/english.php?content=../content/1033/ethercatsystem/402909835.html&id=
+
+To follow this guide, you need to have TwinCat installed and a License.
+
+# Motor does not start!
+
+If the Motor does not start after trying to talk to the inverter, the most common reason is that the inverter's serial connection settings (baudrate,encoding ...) are incorrect.
+
+The correct settings can be found in mitsubishi_inverter.md under `All Settings needed for the Inverter Communication/Operation with Extruder`
