Basic jog physical buttons

Hello,

I'm looking to build a front panel for my CNC little Emco lathe, and would like to get some increment and continuous jog buttons.
I'm new at tweaking HAL config files, and I'm struggling to get the jog work from the buttons.

I've added a second parralel port to get more inputs, and that works well as I can control (start/stop) the spindle.
However, I'm not finding anything that works to get anything to move from that command...

I expected this to do the job, but it isn't, likely somthing is missing or wrong around halui command
In the debut halui window I can see that my button does well affect the True/False state.
I'm using LinuxCNC 2.8

Thanks for your help !

until the machine is homed - you must jog joints, which use different named pins.

Code:

net z-plus halui.axis.z.plus <= parport.1.pin-02-in

Are you setting halui.axis.jog-speed to a non-zero value?

Is the DRO showing XYZ rather than 0,1,2? I would imagine that a lathe would be using identity kins, so probably goes straight to XYZ mode?

Hello,

Yes, I've set the halui.axis.jog-speed, but doing too much testing, I missed to home properly at the end, hence... this

I've been able to jog before homing using joint pins

Thanks for your help ! I now have all the tools I need to code my interface.
