How do I use the filament sensor as a trigger for autoloading??

SanderLPFRG

Hey!

I have the orbiter with orbisens installed.
I currently have it setup so that if there is no filament loaded and it triggeres, it starts autoloading the filament. However, it is now non-functional as a filament monitor.
How do I configure it do do both?? Also, how do I write a custom script/ macro for the actions taken when filament runs out?

EDIT;
What I want do do in short is;
When filament sensor (connected to 2.io2.in) goes from low to high --> filament is getting loaded --> trigger2.g is triggered.
When filament sensor (connected to 2.io2.in) goes from high to low during printing --> filament ran out --> custom script gets triggered

Config for filament sensor;

; Filament sensors
M591 D0 P1 C"2.io2.in" S1 ; simple sensor (high signal when filament present) connected to IO_4 for drive 0, enabled

Config for autoload;

; Custom buttons

You could reconfigure it in your slicer start gcode so that once the print starts, it behaves as the runout sensor.

@Phaedrux
How could I do that?? Because I also need to disasable the trigger button if that is the case..

OwenD

@SanderLPFRG
I could be wrong but I think to have it do both you'd omit the M950
You've already defined the pin as a filament sensor, so just adding the trigger might be all that's required?

If it does work I expect you'd have to do some conditioning checks and use M400 in your trigger to avoid thing happening when you don't expect it.

@OwenD

Thanks for your reply. I understand what you mean with "the pin is already defined", but how do I use the assigned pin to call 2 different triggers depending on the states?

Ideally, I want to be able to call 2 triggers;

When filament sensor (connected to io2.in) goes from low to high --> filament is getting loaded --> trigger2.g is triggered.
When filament sensor (connected to io2.in) goes from high to low during printing --> filament ran out --> custom filament runout script gets triggered

SanderLPFRG

Could I do this??;

Define in config.g;
M950 J1 C"pinx" ; define logical input for E1 filamentsensor
M581 P1 T2 S0 R0 ;define trigger for filament auto load triggers trigger2.g
(trigger 2 being the autoload script)

Then in start gcode add;
M950 J1 C"pinx" ; define logical input for E1 filamentsensor
M581 P1 T3 S0 R0 ;define trigger for filament auto load triggers trigger3.g
(trigger 3 being the filament runout script)

in end gcode I revert it back to;
M950 J1 C"pinx" ; define logical input for E1 filamentsensor
M581 P1 T2 S0 R0 ;define trigger for filament auto load triggers trigger2.g

Phaedrux

I think that may work, but you only need the M950 once at the start.

Do you have a macro for switching to the runout script that just contains this? What do you have in trigger2.g and trigger3.g?

; Filament sensors
M591 D0 P1 C"2.io2.in" S1 ; simple sensor (high signal when filament present) connected to IO_4 for drive 0, enabled

Since the M591 command calls out a pin specifically, you may need to unbind the pin before configuring it as a runout sensor.

For example to set it as the runout sensor

M950 J1 C"nil" ; unbind the pin
M591 D0 P1 C"2.io2.in" S1 ; simple sensor

Then to set it as the autoload

M591 D0 P0 C"nil" ; unbind the pin
M950 J1 C"pinx" ; define logical input for E1 filamentsensor
M581 P1 T2 S0 R0 ;define trigger for filament auto load triggers trigger2.g

Does that make sense?

To my way of thinking, the filament sensor (having been defined as such using M591) already has a trigger from high to low and calls filament-runout.g
You just need to add a trigger for the low to high action.

If you weren't defining a filament sensor, but rather just a normal gpio then you'd define the pin with a single M950 and add two M581 triggers, one with S1 and one with S0

~~I could be wrong, but it's easy enough to test.~~

I was wrong.
M581 won't allow a pin name, so you have to use M950 to define a number which in turn clashes with M591.
So I think you're stuck using two triggers and not defining a filament sensor.
Or do something like @Phaedrux has shown.

SanderLPFRG

@OwenD I did exactly that yesterday late afternoon. It is working now.

; Custom buttons
M950 J1 C"^io2.in"      ; define logical input for E1 filamentsensor
M581 P1 T2 S0 R2        ; define trigger for filament auto load (trigger2.g)
M581 P1 T4 S1 R1        ; define trigger for filament runout (trigger4.g)

Thank you very much both!
