Getting started with a CNC can feel overwhelming, especially when learning how to set up the workspace, secure material, and establish an efficient workflow. Before beginning any cutting or carving projects on a new CNC, one of the first and most important steps is creating a reliable spoilboard. A spoilboard protects the machine bed, allows for resurfacing when needed, and provides a consistent reference surface for precision work. In our shop, we had several Microjig MATCHFIT accessories available, so we decided to build a spoilboard designed to work with their dovetail-based workholding system. This creates a flexible clamping solution that adapts to different project sizes and shapes without adding much clutter to the CNC bed.
In this video, we walk through the entire process of preparing the spoilboard material, securing it to the CNC, creating the toolpaths, selecting the correct router bits, and cutting the dovetail grooves that make the MATCHFIT system possible. The MATCHFIT method works by cutting dovetail-shaped slots directly into the spoilboard, allowing clamps and stops to slide into place and lock down firmly. There’s no need for separate T-tracks or additional mounting fixtures, which keeps the work area clean and easy to configure. The process is approachable, even for those new to CNC woodworking, and provides a hands-on introduction to feeds and speeds, bit selection, dust management, and CNC file setup.
This spoilboard project is an excellent first step for anyone looking to build confidence with a CNC. It sets up a foundation you’ll rely on for future projects, whether you’re carving signs, machining joinery, or experimenting with 3D relief work. Having an adjustable clamping system also makes it easier to hold irregular shapes and switch between project setups efficiently.
