Can't deploy BLTouch clone (3D Touch) Duet 2 Wifi

post your deployprobe file

Hi veti,
here it is:; deployprobe.g
; called to deploy a physical Z probe

try the self test using
M280 P7 S120 I1 -
Still nothing
I wonder if the probe being able to self test at boot but not deploying it manually shows that its either my wiring or an error in the config?Here are the product info if it might help:
Solenoid Push-pin Up servo signal 90Degree(ex : M280 P0 S90 )
Solenoid Push-pin Down
servo signal 10Degree(ex : M280 P0 S10 )
Manual Self-test servo signal 120Degree(ex : M280 P0 S120)
Alarm Release servo signal 160Degree(ex : M280 P0 S160)3D printer z-probe Touch can be operated in the following condition.
- One I/O (PWM or Software PWM) for control
- One I/O for Zmin
- GND and +5V power
If you use this on an Anet A8 then you need to cross over the YELLOW & BLUE wires. Couldn't figure out why it wouldn't work until I read the head unit. The Yellow is the endstop and the Blue is the pwm input, I just cut them and reversed them
Thanks

Can you post a photo of your wiring between the probe and the Duet?
-
The P0 parameter in the product info needs to be adapted to whichever pin you used on your Duet.
But just to cover the basics, when you power on the printer the probe deploys and retracts a few times, and has a steady red light after?

@bearer The probe deploys and retracts a few times at boot and then has a steady blue light
-
switch the blue and yellow wire
-
@veti
I'v switched the yellow and blue wires,
with and without the resistor between blue and black wire as well
still blue led and nothing -
-
The next question now is if you get a trigger signal from that 3DTouch, I've seen several people having problem's on FB groups the last couple weeks including me
-
@exerqtor I can get it to deploy and work but some time the probe extends two times and other times it does not trigger when colliding with the bed

Tbh i just think those sensors are next to snakeoil
Given how cheap the real probes are, it's not worth the potential headache and anoyance any of the knocnoffs can make. -

Given how cheap the real probes are, it's not worth the potential headache and anoyance any of the knocnoffs can make.Some are hampered by steep fees and taxes when importing stuff, clones are usually declared incorrectly and/or below a duty free limit - I think that makes a bigger difference than $15 clone vs $50 real probe, the latter could easily be closer to $100 by the time it is delivered to me.
But thanks to your comment, I checked out their site and found their Ali Express store had a sale, $35 shipped, below the free import limit - yay!.
