Mach4 General Discussion / Short output pulse from Mach4 + ESS
« on: August 03, 2016, 12:01:43 AM »
I've just embarked on my first "cnc" project, I'm trying to make an auto exposure x-y table that basically turns on a laser for a precise time at various positions. The laser is controlled with a TTL signal, and ideally the pulse width should be able to be anything from minutes to ~5 milliseconds. I've started reading the scripting manuals etc, and looks like I can make an M code script quite easily, but I don't know where to start for the core function that would allow such a pulse to be generated.
Does Mach have the ability to generate an output pulse of a precise (say +/- 10%) length? I'm guessing that the ESS will have no problems with a millisecond pulse as it's capable of generating microsecond long pulses for motors etc.
Would I be better off just making a stand alone pulse generator and then communicating with it from Mach somehow?
Thanks for any suggestions you might have
