I am new to cnc and I am not a programmer. I have been setting up my new machine and I'm having trouble calibrating the touch sensor. I need a basic(simple) step by step guide for setting the macro. The sensor came in a box with no paperwork. I have looked at the example macro.cnc in the software but it doesn't work because I have not calibrated the tool.
I know that this is a very basic thing to ask but I would appreciate any help.

Cheers!
