I am testing a new home built router and have not yet hooked up the X Axis.
How can I run a program and manually operate the Z.
Would I edit the G Code and delete reference to the Z and somehow tell it to stop until I have set the Z Axis.
On second thoughts could I mark the reference to the Z in the G Code so that it is ignored or skipped. this would enable me to reinstate the code when I hook up the Z.
The reason for this is that I am not yet competent with Mach3 setup and I don't want to dig holes in the floor of my workshop.:)

use an optional stop or m0 before every z move

Thanks for the reply. However I am allowed one more dumb question.
Do I leave the original code in place and if so will it skip to the next instruction.
What is the difference between M0 and M00.
Make that two dumb questions.
Maybe a small example would help.
thanks in advance

What is the difference between M0 and M00.


there is no difference between the two , if you leave out the zero's the file size is shorter g01 g1 , m00 m0 , i'm in the habit of leaving out the zero's because some of our cnc's have small memory and some of our programs are quite long , plus if your hand programming it saves a lot of needless finger punching

before every z move add a m0

m0
