I am fairly new to running and programming a fadal. my quesion is : on a G84.1 tap cycle what is the Q for? I am still programming a Z value and can't figure out what the Q is.

Also, at the end of my programs to send Z home I have G0H0Z0. What is the H for?

And Finally, why don't I have to use a G43 to comp tool length? All I have to do is call up the H for that tool. IE- H1 Z1. M8

Q is the thread pitch eg 1/4-20 is Q.05

h is the tool length offset

You are experiencing these issue because you are in Format 1. The "Q" is the lead of the thread and the "F" in this case represents the RPM. The G43 code is a Fanuc code for applting the tool length offset. It is NOT needed in Format 1.
In Format 2 there is no "Q" used for tapping, instead it is programmed like the Fanuc with an "S" for the RPM and an "F" for the calculated feed rate. The G43 is required to apply the toolength "H" code in the Fanuc style.

If i switch to format 2, will the g+m code be just like on a fanuc or will there still be some differences?
