M291 T value to return a result

[moth4017]

When using the M291 with a T value for time out , i carnt seem to capture this event .

M291 R"Do you want to Run G29" P"your choice" S4 T5 J1 K{"Yes", "Reuse height map" ,"clear heightMap"} F5
    if input = 0
        echo input
        G29    ; use saved height map
    elif input = 1
        echo input
        G29 S1 P"/sys/heightmap.csv"; load previous height map   
    elif input = 2
        echo input
        G29 S2 ; clear height map
    else 
        echo "no selection pressed" ;G29 S1 ; load previous height map 
        echo input

selection 1 returns this:-
8/31/2024, 4:02:19 PM M292 R{1} S21
1
time ouit selection nothing returned

@moth4017 I think this is related to https://github.com/Duet3D/RepRapFirmware/issues/959. Timing out is equivalent to pressing the Cancel button, if there is one.

@dc42

have i done this correctly to capture the "Time out"

M291 R"Do you want to Run G29" P"your choice" S4 T5 J2 K{"Yes", "Reuse height map" ,"clear heightMap"} F5
    if input = 0
        echo input
        G29    ; use saved height map
    elif input = 1
        echo input
        G29 S1 P"/sys/heightmap.csv"; load previous height map   
    elif input = 2
        echo input
        G29 S2 ; clear height map
    elif input = -1 
        echo "no selection pressed" ;G29 S1 ; load previous height map 
        echo input

@moth4017 What you are seeing is the current expected behaviour, there is a feature request to change this, but I do not think it has been implemented yet (or if there is any commitment to implement it).
