M581 External trigger doesn't execute immediately
-
Hello, I have a question about M581 external triggers. In the documentation it says that the firmware will not wait for queued moves to be completed before executing the macro.
In my config.g, I have the following external triggers defined :
M581 T2 U S1
M581 T3 V S1
M582 T2
M582 T3Below is the macro trigger2.g
M25
G91
G1 E90 F1500Below is the macro trigger3.g
M25
G91
G1 E-90 F1500If I send a G1 E200 F1500 and press the trigger while the extruder is running the command (manually triggering the V axis endstop), the extruder doesn't immediately do the trigger3 which should reverse the extruder (E-90 move). The trigger is executed after the G1 E200 F1500 move is completed.
I tried replacing the M581 definition for T0 (emergency stop) and it acts immediately.
See below my complete config.g file (firmware 3.4b7)

@omiclette Most probably it's the M25 which according to the docs, does this quote ....
"
M25 attempts to execute as quickly as possible and follows the following logic:When RRF receives M25 it will look for a move in the current queue after which it can stop without violating the configured jerk limits.
If it finds one it stops after that move without decelerating (because the jerk limits allow that)
If it can't find one it will plan and execute a deceleration. in this case the pause will occur 1 move+2 seconds after M25 is sent.That means the longest it will take to pause is 1 move+2 seconds. In most situations pause occurs much quicker than that.
" ... end of quote.The way I read that is that it will pause after the current move. What happens if you comment out the M25?

@deckingman I have just removed the M25 and it still waits for the G1 E200 F1500 to finish before executing the trigger G1 E-90 F1500.

@omiclette said in M581 External trigger doesn't execute immediately:
@deckingman I have just removed the M25 and it still waits for the G1 E200 F1500 to finish before executing the trigger G1 E-90 F1500.
It's because it's a long move. You could try segmentation but I'm not sure whether it's applied to extruder moves too.
E.g.M669 S1 T1 -
@jay_s_uk I've just tried putting M669 S1 T1 in my config.g file and the trigger was still not executed until the G1 E200 F1500 was finished. Segmentation doesn't seem to apply to the extruder command.
Still, in the documentation it says that the firmware doesn't wait for queued moves to be completed before executing the macro so I don't understand why it waits...
-
@omiclette because it's not in the queue. It's being executed
-
@jay_s_uk Ahhhh that's true. So if I understand, the feature that allow pausing immediately still doesn't exist (this 2020 thread seems to mention that it was on the wish list : https://forum.duet3d.com/topic/18289/emergency-stop-without-m112/5)
-
@omiclette yep, must still be ok the list. Maybe @Phaedrux can comment whether it is
-
Still on the list.
