There is not set in stone force numbers, Force is determined by how you set up your blade depth to the vinyl that your using. How many different vinyl thickness are you using that you have to keep changing the force on the Graphtec? I only change the force up a bit to cut Avery chrome from Oracal 651. Force also differs as your blade wears down. I may only bump it up 1-2 . If you are using different vinyls. then doesn't the CE LITE have different conditions to set it on? Most Graphtecs have 8 conditions that can be set on the control panel for different types of jobs. Force. Speed, etc. Right on your cutter. Or write it down for your different vinyls. This is how to set your blade depth correctly.
To start with, you should set your blade depth correctly, by taking the blade holder out of the machine, and firmly cut across a piece of scrap vinyl, you will be cutting. You should only be cutting the vinyl and barely a mark on wax paper backing, Adjust blade to get there, Then put the blade holder back in machine, and use the force of the machine to get there, same results, only cutting the vinyl and barely a mark in wax paper backing. You should just barely see and feel the blade tip out of the blade holder.
