BL Touch flashes after homing z

dutti

hey,
I can maka a normal homing z and after it, the BL isn´t working anymore. no m401 / m402( when pushed manually in). It is also flashing red... I can´t stop it.
Sometimes it calls ´´already triggered´´ when trying G32

@barbarossa-cologne said in BL Touch flashes after homing z:

I would check wiring first and whether the core has the right position (allen key on top of the BLtouch).
I would change G31 P500 ... to P25.
I don't know whether io4 needs a pullup resistor at the Duet3, in this case would be necessary to set the ^: M558 P9 C"^io4.in" H15 F120 T1200
=> I found an old thread where you need pullup for both M558 and M950:
M558 P9 C"^io4.in" H15 F120 T1200
M950 S0 C"^io4.out"

Probably nothing to do with the problem, but you have 3 mappings for E, but 6 values for E at the following settings.

Phaedrux

Using your pins in the configurator I get this:

; Z-Probe
M950 S0 C"io4.out"                                    ; create servo pin 0 for BLTouch
M558 P9 C"^io4.in" H5 F60 T6000                     ; set Z probe type to bltouch and the dive height + speeds
G31 P25 X0 Y0 Z2.5                                   ; set Z probe trigger value, offset and trigger height

So you may need the pullup ^ enabled on io4.in

The other thing I notice is that your homez places the probe outside the bed if your G31 X Y offsets are correct.

G1 X15 Y15 F6000 ; go to first probe point
G31 P500 X-20 Y-20 Z4 ; set Z probe trigger value, offset and trigger height

Also Z4 for a trigger height seems very high for the BLtouch.

What is in your homeall?

JoergS5

It was the thread https://forum.duet3d.com/topic/15823/duet-3-inverted-pull-up-inverted-pull-up where it was told that io4.in and io4.out should be pulled up with ^ with the Duet3.

What do you mean with it and how can I change this?

@JoergS5
Yes.. thank you. But the problem is still, that the no touch flashes after doing a z probe. Z probe, but then I have to deconnect the cable and then it's working. M401 / M402.
Also after successfully probe the first point (G32) it's stopping,and it says ''z probe was not triggered during probing move''.

JoergS5

@barbarossa-cologne it is some time ago, so I don't remember well.

First you should update to firmware 3.1.1, if you have an older version.

Then please make an image of the BLtouch 5-pin connector and the wiring on the Duet to check wiring.

In the meantime I know that
M558 P9 C"io4.in" H5 F60 T6000
doesn't need ^ because it already has pullup acticated automatically.

Post your homeall.g and bed.g please.

Let's try and keep it to a single thread please.

dutti

sorry
That was not my plan.....

JoergS5

@barbarossa-cologne in the other thread you say firmware is 3.01 beta 9, you should update to 3.1.1 first before doing anything else.
