# Plug Setup - 3D

## Setup

As before, the Plug Setup is nearly the same as the [2D Plug Setup](https://docs.corbinsworkshop.com/plug-setup-2d.md), while the toolpaths and behavior are similar to the [3D Pocket Setup](https://docs.corbinsworkshop.com/pocket-setup-3d.md) with the toolpath changes noted below.

## 1. VCarve Plug

The Machining Boundary Selection first has the Silhouette added, and then the Sketch Design is second, with it set to "Start Outside".

## 2. Clearance Toolpaths

These are setup identically to the 3D Pocket's clearance toolpaths, except the inset is the `plug_stock_to_leave`, which is a slightly different value based on the full plug depth: `tan(inlay_bit_angle / 2.0) * plug_depth`. The `plug_depth` is `plug_surface_gap + inlay_fit_adjustment`

## 3. Clearance Rest with VBit

Same as 3D Pocket, but `-plug_stock_to_leave` is the boundary inset.

## Multiple Depths or Roughing with Pencil

Most toolpaths have "Multiple Depths", but Pencil does not. To work around this, right click on the Pencil toolpath and select **Duplicate**. Rename the first one “VBit Rough”. Double click on it to edit it. On the **Passes** tab, check\*\* Stock to Leave\*\* and set the **Axial Stock to Leave** to be half your inlay depth. IE: if your depth is 0.200", set it to 0.100".

Doing this will generate a light first cut. The plug generally cuts deeper, and you may need to do two roughing passes with varying stock to leave.
