@Phaedrux i found a scratch in the top of the effector . any idea how to fix it ? Or the only way is to order a new one ? Greets and happy new year.!

unfortunately yes.

Hello and I wish you a great new year eve,
I installed a smart effector in my Anycubic predator together with a duet 2 wifi. after powering the predator, the light in the smart effector starts to flash 7 time. according to the wiki : 7 flashes= train gauge output out of tolerance (too high)
I checked all wires many time and it seem everything is ok.
doest it mean the smart effector is effect? what would be the cause ?

Hmm..
I attached the laser to the Laser pin and used M452 C"out9" Q100 but it doest work. I tried all possible combinations. Also !out9.

I put the laser to in the out 9 (2pin for fan not the 2+3 for Laser)
In laser mode the PWM doesn't control the laser. laser doesn't react on M3, G1, M106 .
in FFF mode I can control the power of the laser with M106.

For laser mode I was using: M452 C"!out9" Q100 to create the laser pin.
Now I am using M950 F0 C"out9" Q100 T1 to create Fan 0 .. only after deactivating the M452 I can control the laser/fan with the M106. G1 Sxxx doest work in that case.

Any hint what I am doing wrong.

THANK YOU all for the inputs. I tried all possible possibilities but no one is working.
the last what I tried:

I connect the laser to the out 1 (heater 1) and declared it in the config: M452 C"!out1" Q200
The light next to the output 1 is now red.
If I send a command (M3 S100 or M106 S100) nothing happens.
I inverted the wires and the laser got constant signal and was working in full power although the laser is in PWM mode.
did I missed something in the the config files?

the schematics and further information are to find under : https://endurancelasers.com/development-of-an-endurance-mo2-pcb/

@bearer
unfortunately, doesn't help.
do you know if the pins Voutlc_6 and out6 are the right pins to use? I am not very familiar with laser PWM signals .
greets

the laser head is connected to the laser box with following schema:

endurance laser suggests to connect the wire to the pin in fan0 but for the duet 2
I can't find any information related to duet 3

Does anyone have an idea? it drives me crazy.
my last try was:
in the config.g file I declared the laser modus with: M452 C"out6" Q100
the laser is attached to the 4k connector for fan (output 6). I wire only the pins: "v_outlc6" and "out6"
But no chance. I can't adjust the output intensity of the laser. I am using M3 SXXX as a command.
thank you.

Hi,
I am using duet 3 with Rpi 3 for my Workbee.
In the moment I am planing to use it as laser engraver. I am using an endurance laser but somehow I can't connect it to the duet .
The Laserbox of the endurance has two wires (black and red). In the endurance website, it shown only how to attache the endurance to the Duet WiFi. The two wire has to be attached to the connector fan 0.
I tried to wire them in different way but I couldn't control the laser with M3 . I go only permeant laser with full power.
Any ideas how should I wire the box and configure it ?
thank you in advance.

Hello Phaedrux,
Thank you for your answer. could you please tell me how I can update from Firmware 3.0 to 3,01 RC10 using my Rpi?
regarding the other config call, it is empty.
Thank you in advance.
