Let me see if i understand your situation. Your setup is this:
You're using Axis as your GUI, and you're using a jog pendant. The
pendant uses halui to jog the machine, and can trigger MDI commands for
things like Z touch-off.
The problem you're having is this:
Sometimes when you pick up the pendant, LinuxCNC is in the wrong mode
and you can't jog using your pendant.
Is that all right?
Chris Radek, Dewey Garrett and I talked about this problem on
#linuxcnc-devel a bit, and we came up with a different solution, that we
started to implement and that's not yet done, but is in a testable state.
Look at the halui-jit-manual branch on git.linuxcnc.org. It does two
things:
1. Teach the Axis GUI to detect what mode the controller is in, and
display the appropriate tab (Manual or MDI).
2. Teach halui to switch the controller to manual mode automatically
when the user requests a jog.
The changed behavior is that if you're in MDI mode (F5 tab displayed in
Axis) and you poke the halui.jog.*.{plus,minus} pins in HAL, halui
switches to Manual mode (and Axis notices and switches to the F3 tab)
and does your jog.
I know of two problems with that branch:
1. It breaks jogwheel jogging somehow (motion no longer responds to
axis.*.jog-counts).
2. There's a perceptible delay when halui switches mode to task=manual,
which makes the jog feel jerky
Does this new behavior address your issue? If so, further testing &
development in this area seems worthwhile.
