M66 IF Request in Subroutine

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:

My G4 P0.5 Works correct... the problem is the second if statement

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

ok you have to describe in detail what the signal levels are when, what is expected and what is happening. i checked the thread, you only say "it works" or "it doesn't work".

i'm pretty sure the variable is written like it should, so something else is going on.

when O104 is not ok then -1 will be written
when O104 is ok then +1 will be written
when O105 is not ok +1 is written
when O105 is ok +1 is written

the 2 sensor are ok when it changes to high

sensor 1 high ok drawbar is open
sensor 2 high ok tool is clamped

but the drawbar (sensor 1) most be close before i can check sensor 2 (clamped tool)
