Hello-

I have been using a shopbot for a while now, and I am considering building a router that would be controlled via Mach 3.  The shopbot code is a similar syntax to g-code, but one thing it has is the ability to specify variables in the file instead of hard coding feedrates, etc. It also has the ability to use conditionals and loops, etc.

Is there something similar that can be done with Mach 3 and g-code?

thanks,
Howie

Yes, you can do things like this:-

#100=5
G00 X[#100*10] Y[#100*10]
M30

Graham.

Can you do any commands like, IF [#101EQ0] GOTO10?
Is it possible to get a list of all the possible variable commands.
