Title: operating relays
Post by: comet on February 08, 2010, 10:09:36 AM

Hi,
 I need to operate some relays to opreate work clamps etc.
I know I can use spare coolant g code, but how do you do it without
using g04 Is there spare g or m numbers that can be used?

You can make up custom macros and have the dwell in the macro itself then you would just call the macro with the M code you called it, for example if you called the macro m123.m1s, you would call m123.

Thanks, but that leads to the question,how do you do macro's?

Well you could have something like

Activate Signal (OutPut3)
Sleep (2000)

What that would do is switch on output 3 then wait for 2 seconds then Mach would again carry on.
To switch the output off you would write another macro and have

DeActivateSignal(OutPut3)
Sleeep(2000)
