Max X and Y point

[xavimon]

Hi, I am Xavier
I am working on a custom 2D laser machine. First, I want to thanks the great work devs did with this software.
I am using Lasergrbl with modifications to adapt it to my needs. I running out of time now and I need help for something.

Let me explain, if I need to cut a 30cm x 50cm figure, I need to obtain the value of 30 and 50, that's all, the maximum size of the figure on the X and Y axis. (i can use only svg files).

What do I need it for? Well, I'll take the maximum value of X or Y and make Z axis ( another stepper motor) move that amount of cm after finish the work.

I have one solution for that problem:
Write the size of the figure in the file name, internally I can get the address and name of that file (C:\tests\myfiletocut_30x50_.svg) and get it from that string.

I was wondering if there is a better way to do it, get those values directly inside the program code.

Thanks for u help.
