Hello, I'm currently trying to do security queries in the subrotines. This is mainly about the M66 query. So I'm trying to make 2 M66 queries in a subrotine that I want to query with an If statement. The first m66 query with if statement always works but with the second m66 query with if statement it fails because it doesn't write the value to the var

How can i do that?

    M64 P07 ; open Drawbar
    M66 P31 L3 Q1 ; wait for drawbar open
    O104 if [#5399 LT 0]
        (abort, failed to open drawbar)
    O104 endif
    G1 G53  F2500 Z-100
    M65 P07
    G4 P0.5
    M66 P29 L3 Q1 ; check for tool
    O105 if [#5399 LT 0]
        (abort, failed tool not clamped)
    O105 endif
    G0 G53 Z0

That looks correct. Are you sure your signal routing is correct?

This is how I do it and contrary to some comments in another thread this code actually works.

g4 does only prevent axes from movement, for other, there is no effect. If you need a delay and increasing timeout does not work maybe try mcode,like:
#!/bin/bash
sleep .5
exit 0

so you say if you enter those commands in MDI it works but executing in one file it doesn't?

M66 P31 L3 Q1 ; check for drawbar
O104 if [#5399 LT 0]
(abort, failed drawbar not open)
O104 endif

M66 P29 L3 Q1 ; check for tool
O105 if [#5399 LT 0]
(abort, failed tool not clamped)
O105 endif

does not work. O105 dont write the parameter 5399 new

M66 P29 L3 Q1 ; check for tool
O105 if [#5399 LT 0]
(abort, failed tool not clamped)
O105 endif
In a single file it works

M66 P31 L3 Q1 ; check for drawbar
O104 if [#5399 LT 0]
(abort, failed drawbar not open)
O104 endif
In a single file it works
