Jog with encoder and key.

Hello...

I have homemade pendant with encoder wheel. It works nice. But the machine is large and I don't like to spend all time to travel from one side to the other to rotate that knob. But I had key available to do jog with max speed, but cant find solution where I should connect it in hal.
So in short. For long travel Id like to pres key on pendant to go as fast as possible. And when I was close to destination to use encoder wheel.

It\s should be possible as if I press cursor keys on keyboard the machine just do what I want. ..just the keyboard can be few meters away.

Hi

A simple way would be to use halui
www.linuxcnc.org/docs/devel/html/gui/halui.html

eg.

setp halui.jog-speed 1000
net posjogX halui.jog.0.plus <= parport.0.pinN(connected to your button)

NB AFAIR speed must be set even if you just use the increment pins or the axis will not move

regards

Thanks....

I forget to set speed...
