Need help to set up filament runout sensor

[PuddingBaer91]

Hi
yesterday i updated my anycubic predator also to a duet wifi 2 board. Now i have the smart effector with the duet board

I managed all to work except the filament runout sensor.
In my config.g i added this line:

M591 P2 C"e0stop" S1 D0                                ; Activate filament sensor connected to E0 endstop

if i send M591 D0 to the duet i get "filament=no" if filament is not present and "filament=yes" if it is present. So the sensor itself works fine i think.

What i want is: run a "anyname.g" - file when a filament sensor change is happened (from active to non active (from filament present to not present))

To test the sensor working like i want i created in system folder the trigger4.g file which contains the command to enable the part cooling fans to 100 % (Just to test the state change from sensor)

In config.g i added the lines to call the trigger4.g:

trigger4.g
M581 T4 S0 R0 E0             ; trigger for filament runout sensor, T4 = trigger number

because of R0 it should trigger even when not printing. But if i pull out the filament from the sensor the part cooling will not activate.

I read the wiki and tried some things but it's not clear to me how i assign a trigger number (T4) to a .g file. May i understood this wrong. Hope you can help me Thank you

This is my config.g:

[Phaedrux]

Put a ; in front of trigger4.g

lemme double check the usage of M591 and M581

[PuddingBaer91]

@Phaedrux the added the ; but no change. I only added this line because i thought this way the T4 parameter is assigned to this file...

[Phaedrux]

I think the problem is that you are trying to use the same switch for filament sensing and as a trigger at the same time.

The filament sensor behavior is to send a pause command when the filament is not present.

If you want to use the switch to trigger a custom macro, you would just use M581.

It has been requested previously to allow for a custom macro on filament runout and it's on the work list.

https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M591_Configure_filament_sensing

https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M581_Configure_external_trigger

So in the meantime, configure as one or the other.

[PuddingBaer91]

@Phaedrux thank you i will try. Also found that trigger T1 resets the board, T2 pauses and all numbers above executes triggerX.g files. Is this in RRF3 still the case? I can't find this info in the wiki. I found it by google...

Thank you for your help. Will report the result

[PuddingBaer91]

Okay now it works. I just deleted the trigger code...
A few other questions i dont want to open a new thread:
I always calibrated my delta in cold state (heaters off) now if i want to always calibrate before a print starts should i do this in cold state? I ask because if i also want to use mesh compensation i have to do this with heated bed state. Should i also always do a mesh compensation after delta calibration before each print? Or just load a state after calibration?

It's literally in the link I posted above.

Trigger number 0 causes an emergency stop as if M112 had been received. Trigger number 1 causes the print to be paused as if M25 had been received. Any trigger number # greater than 1 causes the macro file sys/trigger#.g to be executed. Polling for further trigger conditions is suspended until the trigger macro file has been completed. RepRapFirmware does not wait for all queued moves to be completed before executing the macro, so you may wish to use the M400 command at the start of your macro file. If several triggers are pending, the one with the lowest trigger number takes priority.

I think it's usually best to perform any calibration in a hot state to better match the thermal expansion changes that happen during the actual print.

[PuddingBaer91]

thank you

Another thing i noticed: If i probe the bed in DWC the z-probe shows most time 0 but sometimes it shows a red 1000. Is this normal? Probe triggers at all cases correct...

[Phaedrux]

@PuddingBaer91 Yes that's normal. The web interface can't update fast enough for probes that only briefly show the triggered state.

[PuddingBaer91]

thank you again
another thing

If i heat the hot end the probe led flickers. If i set the sensity to 70 it's gone. Is this way okay or do i have to check/change something?

[Phaedrux]

@PuddingBaer91 said in Need help to set up filament runout sensor:

If i set the sensity to 70 it's gone

What does this mean?

If the probe is still functioning normally I wouldn't worry about the flicker.

[PuddingBaer91]

i meant the sensity parameter for smart effector:
