Canvas use

Hi Charlie,

I have made several sign projects with various techniques. Raised letters, Vcarve, relief objects, etc.... All of my projects use a base raster layer. I don't understand where the canvas fits in. I know it defines your work space, but so does my base raster layer. The only thing as far as I see is if your project does not need to be cut out,then the canvas layer is the only thing needed.  Is the canvas layer redundant or am I missing the purpose and aimlessly wondering off ?

Thanks Joe


Hi Joe,

The canvas allows you to use a blank slate as your base - so that you can composite a project from scratch without requiring an image or model that comes from somewhere else that serves as most of the project's design. e.g. a project made of a bunch of individual smaller parts and some text rather than just one big image that covers the whole thing.

For instance, the signs my wife designed that we make for sale on Etsy are just an assembly of multiple parts she found and bought to use, different ornate pieces that she chose to use and where to use them. I took that idea and incorporated it into PixelCNC so that you could effectively do the exact same thing without using an external image editing program to do it.

You don't have to design projects in PixelCNC, and just load in a single image or a single model etc... but the option is there for users to streamline their workflow by eliminating the need for multiple tools ;)

Ok ..I got that. The canvas is just an overlay for your work-piece ?  You cant actually cut out the canvas ? You would need a raster path on the canvas , such as rectangle , oval or some other shape . Unless the work-piece does not need to be cut out and is already shaped as you want. then the canvas is just an overlay on that ?



Hi Joe,

The canvas is really just the volume within which cutpaths are generated within, which can be larger or smaller than your actual workpiece. You can think of it as just the size of your workpiece if that workflow is easiest for you but it doesn't have to be the size of the workpiece as long as you are aware of how it's just a volume of cuts and how that translates to the workpiece based on where you set your machine origin on both the canvas and on your workpiece.
