Adding a ShuttleXpress

So it's now working.  I've edited the shuttle hal file to include the A axis which meant adding the logic component for 3 input OR gates. 

The problem with not moving after a g-code program ran was this line and the one for .minus was needed for each axis.  Once done the all axis homed condition no longer prevented outer spring loaded wheel motion.

net sxp.jog-x-pos and2.sxp-x-pos.out => halui.joint.0.plus halui.axis.x.plus

I've also adjusted the step and the move rates to be more useful for rapidly approaching a point and then sneaking up to it.  As yet I have not figured out how to update the drop down list in the axisui to reflect the current step distance.  But then the HBO4 doesn't do it either but it has an LCD display that shows this.

Enjoy.

Big thanks to @jcdammeyer.image missing /media/kunena/emoticons/smile.png This really saved my day after fiddling with several configs found on Github and other forums for a couple of weeks. Worked straight out of the box!

This config also contains some awesome work to avoid having to hold axis-button and jog-wheel at the same time. Makes Shuttlexpress a really good pendant.

So for anyone else trying to connect a Shuttlexpress to LinuxCNC 2.8.4: Use the link above (attachment, button with i on).

If you dont have A-axis just comment out anything to do with joint.3. If you dont, you will get an error when starting LinuxCNC.
 

I am attempting to use the hal code published by jcdammeyer towards the end of this thread but ran into something confusing.

In the beginning of his hal files he does a Loadrt mux2 but although loaded there are no addf mux2 lines AND I do not see where mux2 is used in his code anywhere.

Am I missing something here?
