Nesting Parts
« on: February 07, 2011, 06:15:28 PM »
I have several items of code which were nested using using fanuc code. I want to run them on mach3 but it can't handle the fanuc variables.  Does anyone know a work around for this? The parts are nested in rows and columns, it's the # variable that spits it back out, example code below.

Thanks

(Standard Fanuc)

(x step 50, y step 40)

It is not the # variables that is the problem, it is the conditional code that is the problem.  Mach does not do conditional code

You need to change the section that offsets the parts - it looks to me to be a 3 x 4 array pattern that it is cutting. you have 3 positions in X 0, 50 and 100, and 4 posuitions in Y 0,40, 80 ,120


so where your while statements are you would need to put something like this (THis may not work as written, just looked at your code and then read the book) I would be more likely to use work offsets as there are some other advantages.

and replace  where (profile) is in the code
and stick  an M99 whereright after the G0 Z10.0
