BLTouch not responding properly Duet 2 Wifi

TokeDK

The wires seem fine... Could it have something to do with the BLTouch 3.3v logic bridge (as shown here)
In the video he says to test it with a multimeter? Here I'm guessing you test the continuity? And it's suppose so show 0? On my multimeter it doesn't shows that there is continuity, and I'm sure the bridge is gone...

if you have the version 1.04 you do not need to cut the line anymore

what version bltouch is it?

with the bltouch you will not see 1000 because it just triggers it for a split second.

I believe the BLTouch is SMART v.1.0

The previous owner sold it with the BLTouch now working. He said it was a firmware issue on the original board.

I got a spare BLTouch with the deal, and both are returning the same error.

Now my endstops are not working... I tried to rebuild the config from the configurator with no succes.

First I got the error "failed to enable endstops", then I changed my config to:

; Endstops
M574 X2 S1 P"xstop"                                ; configure active-high endstop for high end on X via pin xstop
M574 Y2 S1 P"ystop"                                ; configure active-high endstop for high end on Y via pin ystop
M574 Z2 S2                                         ; configure Z-probe endstop for high end on Z

Now when it's homing the endstops doesn't work, so the stepper motors keep going...

thats a delta. you have 3 endstops for each tower

try

M574 X2 S1 P"xstop" ; configure active-high endstop for high end on X via pin xstop
M574 Y2 S1 P"ystop" ; configure active-high endstop for high end on Y via pin ystop
M574 Z2 S1 P"zstop" ; configure active-high endstop for high end on Z via pin zstop

M574 Z2 S1 P"zstop" ; configure active-high endstop for high end on Z via pin zstop

Perfect! Now endstops are working. Although Z probe is still giving the same error:

	Error: Z probe was not triggered during probing move

post a picture of your wiring

Veti

you really should recrimp your cables.

can you try without extension cables? like this

Awesome, I set it up like you suggested and it works! So it is faulty wiring/connections. I will report back with my findings.

@TokeDK
i suggest you get a crimping tool (i use engineer pa09). that way you can crimp the cables with the connectors supplied with the duet. (if you got them)

Hi,

I suggest you get the proper connector parts for the Duet board and redo the wiring as needed.

This is the tool I use for crimping the them:
