Re: Cncpro/Gcode

Hi everyone!
I have some questions on CNCpro and G-codes. If anyone can help that
would be great!

1) What is F5-F8 I01-I04 for?
2) It has "V" (varibable) but I am not sure how to us this?
3) It has L (loop g-code) but I am unsure how to put this
into a line, can anyone please provide me with an example?
4) what is E-stop for? (emergency stop??)
5) How and why do you use subroutines?
6) why would you use tool "length" compensation?
7)how do you use machine offset coordinates?
8)do I generally want to keep <V> const. contour off or on?

Thank you again, I realize there are a lot of questions and any help
on any of them would be greatly appreciated!

take care
