We have a Silhouette Cameo 4 vinyl cutter which can also operate as a pen plotter (although in a more limited fashion).
There is no cost to using the vinyl cutter, blades and a selection of vinyl colours are provided, with matt black and matt white being kept in stock most of the time.
The machine can be used by creating a vector drawing in software like Adobe Illustrator, CorelDRAW, Affinity Designer, or Inkscape. The file is then saved as a .dxf format file which can be loaded with the free Silhouette Studio software.
There is also a license for Silhouette CONNECT software available to enable direct cutting from Adobe Illustrator or CorelDRAW if necessary.
