One of the great things you can do on a CNC router is a double-sided sign. There are some key points to making this work, and work correctly.
- – Controlling depth of cut so you don’t cut through when you cut both faces
- – Controlling the model position in the project when you’re using 3D clip art
- – Registering correctly when you flip the board so that both faces are identical and identically positioned.
For this project we’ll be using VCarve Pro software, and doing the cutting on a ShopBot benchtop CNC with an ATC, automatic tool changer.
Within VCarve software you can easily control the position of the model. This is done under the toolpath tab using the Material Setup function. We can use this to make sure that, when cutting from both faces, we don’t cut through, and also to position the 3D carving relative to the text.
Registering both faces
It’s easier than you might think to cut both faces of a double sided sign and make certain they’re correctly registered relative to each other. We’ll do this by pinning the project board to the spoil board. You’ll learn how to create the registration holes in VCarve, and how to take advantage of that when mounting your project board.
Cutting your project
Four bits are required for this project, and it’s hard to beat having an automatic tool changer to take the project from start to finish. No stopping and starting and redoing Z-Zero with each bit change. An ATC provides a very efficient way to cut your project.
