M64 and M65

Hello,
can someone tell me in what kind of way i can switch on and off an outputpin with M64 and M65? I use wheezy with Linuxcnc 2.7.8.

Thanks

Hans

The M64/M65 codes control the hal pins "motion.digital-out-NN".
so to make the value of the hal pin motion.digital-out-00 true you would use this in your G-code.

Hello Todd,
i write this line in the custom hall: net motion.digtal-out-10 hm2_5i25.0.7i77.0.0.output-10
but this does not work.
What is my mistake?

your net command needs to reference a signal name. The signal name is an arbitrary name you create.
So if your digital out put is for turning on a blue light you might want to use a name like this.

Also, by default you will only have 8 digital-out pins. But you can increase the number with a command-line parameter (num_dio) to motion (loadrt motmod).

I think, there are only 4 by default, see:
