Lathe Reverse Sign of X values in G-Code

The document will show a step-by-step of how to step up a tool to reverse the X sign in the G-Code. This will be necessary if your machine uses negative X values to move towards the center of rotation. You will change the G-Code by checking off the box that says “Reverse Sign” in the tool library.

Definition:

Reverse Sign

- With this check box cleared, the output of the X value maintains its default behavior. A move toward the center of rotation will be output as a negative move and a move away from the center of rotation a positive move.

- With this check box selected, the output of the X value reverses. A move toward the center of rotation will be output as a negative move and a move away from the center of rotation a positive move.
