I'm having a hard time grasping the tool length offset (G43) But my question is this. Can't you just touch each tool off a gage block of say, 2" and then hit the "Set tool offset" button? Then once the tool is called in the program Mach willl adjust for the given height. Is this how it works?

Nobody Knows?

You will need to include the line G43 H* where the * is the number in the tooltable that you wish to use for your offset.
