+# Interface
+
+The CAM interface is, in most respects, the same as the [general interface](/kiri-moto/interface). It is highly recommended to familiarize yourself with the general interface before using the CAM interface.
+
+With that in mind, here are the key differences:
+
+## Operation List
+
+The Operation List defines the order in which operations are
+performed on the model. Selecting the **plus** button will open a
+popup menu for choosing an operation to add. The operations are
+draggable, enabling easy re-ordering.
+
+- An operation can be disabled by **Ctrl+clicking** it. Disabled operations will be skipped in the slice/preview/export process.
+- The thin blue bar in the Operation List is also draggable. Moving the bar automatically disables all operations below it. This allows you to slice, preview, and export up to a specific point in the timeline.
+
+<ImageCarousel base="/img/CAM/interface/" images="camInterface" sml />
+
+## Origin Selection
+
+Origin Selection (introduced in v4.3) enables automatically setting an origin to points of interest on the model, including corners and arc centers.

+
+For the CAM interface, click [here](/kiri-moto/CAM).
+
+![A minimalist approach](/img/interface/main.png)
+
+## Top Menu
+
+- **Left:** Buttons to move through the `Arrange → Slice → Preview → Export` workflow. These steps are also available as [keyboard shortcuts](/kiri-moto/controls). Selecting an option here will automatically run prior steps as needed.
+- **Center:** Clicking the [logo](/kiri-moto) opens a dialog with version selection, helpful links, and your current Kiri:Moto version. If you are unsure which version to use, check the [release notes](https://github.com/GridSpace/grid-apps/releases/) on GitHub.
+- **Right:** Options for importing/exporting the workspace, manipulating the view, changing modes, and setting preferences. Kiri:Moto currently supports CAM, FDM, SLA, and LASER modes. Some other modes are extensions of the LASER workflow, but do not have first-class support. The [preferences menu](#preferences) will be covered later in this section.
+  - Changing the mode updates the left menu and enables/disables mode-specific options such as the `CAM Operation` menu and the `CAM Animate` step.
+  - Learn about K:M file types [here](/kiri-moto/faq#what-are-the-kmz-and-km-file-formats-short-for).
+
+## Left Menu
+
+The left menu contains options for the current mode. These vary widely:
+
+- CAM has ample documentation on [Process Options](/kiri-moto/CAM/processOpts).
+- Other modes are less documented but many options are self-explanatory if you're familiar with the manufacturing process.
+- Hovering over an option provides tooltips. When in doubt, a quick search usually explains the option in detail.
+
+## Right Menu
+
+The right menu contains controls for objects in the workspace.
+
+- Hovering over the arrow next to an object reveals options for deleting, renaming, disabling, or replacing it.
+- Disabled objects remain visible but are ignored during slicing and exporting.
+
+## Machines Dialog
+
+![Device Dialog](/img/interface/CAMDevice.png)
+
+The device dialog is accessed through the settings dropdown. It allows you to configure a device or select a predefined one.
+
+- The dropdown only shows devices available for the current mode.
+- Stock device settings are greyed out. To modify them, click `Customize`.
+- Learn more about how K:M handles CAM devices [here](/kiri-moto/CAM/machines).
+
+## Preferences
+
+Application preferences are also accessed through the settings dropdown. These are mode-dependent but share many common options. For example, CNC preferences include animation controls.
