@markz That was the golden nugget
Took me a few days, (a week, fffff) but yeah I'm not using OpenPNP so I have to create this in python directly, and the secret was in using G31. I really appreciate your help.

Okay I think I've made some progress.

M950 P2 C"out0" ; should in theory assign p2 to out0?
M42 P2 S1 ; should turn on p2
M42 P2 S0 ; should turn OFF p2

HOWEVER, none of these actually turn off out0, kinda. M42 P2 S1 takes out0 from 9v to 24v, and vice versa for S0, but it never really turns off. It is not in my config.g anywhere.

@chronolite said in Duet3 PnP Vacuum Sensor or Trigger?:

M950 P3 C"out3" ; create Vacuum Nozzle P3 0 on Pin OUT_3

can I trigger so the outX retracts the nozzle as soon as the vaccum is detected?

Then when I turn off the vaccum pump, trigger back down?

or is there a way to make this a sensor?

I have a large CoreXY machine that I'm trying to configure as a Pick and Place. I'm having trouble understanding the usage for detecting vacuum. The wiki has an example for PnP:

https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_OpenPnP

But when you get down to the end, it says "to be completed"

Here's my situation:

I have two "pickers" with vacuum cups attached to outputs (active output = picker goes pick). Then, I have two vacuum generators with "achieved vacuum" switches on them.

Do I set these "achieved vacuum" switches to sensors or triggers?

I guess what's my config.g look like here?

Here's a pic/diagram:

What do I do here?

; Fan Control
M308 S3 Y"mcu-temp" A"MCU" 							; configure sensor 3 as on-chip MCU temperature sensor
M308 S10 Y"drivers" A"MCU2" 						; configure sensor 10 as on-chip driver temperature sensor
M950 F2 C"out1" Q30000 								; create fan 2 on pin fan2 and set its frequency
M106 P2 H3 T28:40									; set fan 2 temp range (T:) and Sensor (H) values, at T28 deg C, fan will be at 40% power

; Vacuum Control
M950 P3 C"out3"									; create Vacuum Nozzle P3 0 on Pin OUT_3
M950 P3 C"out4"									; create Vacuum Nozzle 1 on Pin OUT_4
												; Vacuum nozzle input 0 on Pin IO_0.in (green/white)
												; Vacuum nozzle input 1 on Pin IO_1.in (red/blk)
												

; Activate Card Grabber							
												; extend cylinder 0 on Pin OUT_5
												; extend cylinder 1 on Pin OUT_6 
												; Cylinder0 retraction detect on pin i02.in
												; Cylinder1 retraction detect on pin i01.in


; Led Control
												;LED is on OUT_0 

Thanks in advance...
