Hello,

I created a User led with a user button, and i'd like to have this LED to be lit (turned on) by default when i launch Mach3
, and then when i would  press my button it would  turn the LED off.

I would like to know if there's a way to do this as LED states don't appear to be editable.
Maybe i should try to edit (carefully) the XML to force mach3 to light my LED as it starts ?

Thanks

You could create a macro to turn the LED on and have the m code of that macro in ithe initialisation string.

Thanks Hood.
Could you explain me more or give me an example please ?
You mean the LED would be turned on by the G-Code ?
But what if i don't load any G-Code ?
Thanks

If you make a macro that switches the LED  On then save that macro in the macro folder of the profile you use. If you save the macro as , say, m101.m1s then enter m101 into the initialisation string  (General Config page) when you start Mach and press Reset the LED will be turned on.

OK thanks Hood !
I understand now.
I didn't know about that initialisation string...Now it's done .
Thanks again.

Hummmm.
How do i switch a LED ? (just the LED)
There's no kind of 'SetOEMLED' instruction.
I need to turn on an output to do this, but it uses a spare output...

I dont know what number you are using for the LED but something like this (where **** represents the number you use) should work.

SetUserLED(****,1)

SetUserLED (*********,1)

Excuse me , i haven't looked at the documentation enough.
I thought the SetUserLED wasn't existing !!!!!
I'm an idiot !
Thanks Hood & ger 21

No probs, the documentation is not the easiest to follow at the best of times
