I have had this issue before. When V carving small text on a bunch of the same parts my Xcontroler get very confused. This happens after homing and after Z probing and slightly changing the depth of cut of the text block and the material thickness. No matter how many times I slightly change the material thickness the XCarver either air carves or just scratches the surface. Even if the cut depth is set to 1/4" (.25) it air cuts.
I researched the forum about V bits and text size. Then I got to thinking which is very dangerous. Easel Pro is in the cloud. I am using a wireless laptop. When sending the G code, the program must do some simple arithmetic to calculate the actual depth of cut.
I believe some of the code is not re-calculating when changes are made and the project is online. I tried refreshing the screen but that did not work. After ruining many $5 parts I decided to clear the code by going to bed and starting the next day. IT WORKED!
Is there a command to clear the code? We are feeling better now.
