My plotter isn’t cutting correctly. How do I calibrate it so that it cuts correctly? It is either cutting too deep or not deep enough.

Answer 1: Try a 25 or 30-degree blade. 

Answer 2: You need different blades for different films. Use a 45-degree blade for ceramic and a 30-degree film for standard films. You can actually save your calibrations for each film type, allowing you to easily switch the blade settings based on whichever type of film you’re feeding into the plotter.
