external trigger only triggers once ?

Just setting my two external triggers and doing a little testing.
My button is a normally open switch and I'm connected to the two insides of the connector Gnd and in?.in

; External Triggers
M950 J0 C"io5.in"
M950 J1 C"io6.in"
M581 P0 T3 S0 R0 ;
M581 P1 T4 S0 R0 ;

trigger3.g
M117 "Trigger3"

If I press my button I get my message as expected , but this only works once , I've tried raising and falling edge with the same result.

What firmware version are you using?

If I recall correctly (in succession), M117 will only display once unless the message changes.
Try something like

M117 "Trigger 3 activated at " ^ state.upTime

@owend Spot on !!!!!

I replace the M117 with a echo "Trigger 3", and now each button press and equals a messages on the console.
