You set the scope for single trace capture and trigger on velocity
you also need to set the trigger position a bit above 0 for positive jog
(Trigger threshold is the dotted line)

Yes, now i see some movement if i jog.
But stil don't know what to print out.
As machine is running normaly with jogging on homed or unhomed axes.
Only issue is with the probe when trigged manualy withing jogging if axis are already homed.
Like for instance you would like too measure the touch sensor height (where it kicks in)
So you jog manualy onto the touch sensor and than, when touch sensor is activated, the Z axis moves upwards a few steps.
Not to be confused with touch off routine. That works flawlesly.

I think a unexpectedly triggered probe input causes a fault
so you get an immediate stop. Pretty sure this is expected behaviour

It was not so on previous versions. Behavior was same if homed or unhomed.
But I know it was this way, as i recently manualy remeasured the touch probe height on my old configuration and did manualy jog onto it, and there was no reverse after touching it.
But cant check the old computer with stepconf anymore as it's also upgraded to new version and stored as spare.
However, i don't find it problematic, but it just seemed weird to see different behaviour if homed or not.

Yeah the homing thing is unexpected but a probe hit during a jog is a fault condition AFAIK and not something that's in the range of expected usage

I don't think so.
One option might be to add another relay, NC type, in series with the NO relays on the board.
Then if all outputs are high, the NC relay is open, and if all are low, then the NO one os open.
So the only way that the spindle will run then is if LinuxCNC is actively driving two outputs in to different states.

Is it possible to change the Output State for the Relays on the triple beast within the Firmware of the Mesa 7i92 ?
So the relays are off when Linuxcnc isnt running.
