Red background in web controller

Nylkos

When the output voltage is 0.10V, you should get a reading of around 30 if the connections are good and the configuration is correct.

@fulg:

Try to debug this one step at a time.

IMO, to do so I will require to do and redo some testing
Let me know if you have any idea on how to do this correctly…
Since I am using the Duet 0.8.5:
Wire configuration:

White (OUT) to AD12 (Z-probe section)
Black (GND) to GND (Z-probe section)
Red (+5V) to 5v Pin 1 (+5V)
Orange (Control) to pin 21 (heater 3)
Brown (GND) to pin 2 (GND)

For the Connections:

I will move the BLTouch to be plugged almost directly on the board (require room to plug the multi-meter
I will remeasure the voltage for the white wire for the pins in and out

Is there any more verification that I can run on the BLTouch or the duet 0.8.5 hardware directly?

Software wise, Firmware is up to date (Duet 0.8.5 & Web Controller)

Until I can make sure that I can get the value in Z-Probe down to zero I will not look at other files then the config.g

Added to config.g:

M307 H3 A-1 C-1 D-1
M558 P5 X0 Y0 Z1 H5 F100 T2000
G31 X30 Y18 Z1 P25

For the Commissioning and testing:

M280 P3 S10 I1 deploys the probe
M280 P3 S60 I1, retract the probe

Is there anything that I should test or take a look at?

Thanks you

@Nylkos:

For the Connections:

I will move the BLTouch to be plugged almost directly on the board (require room to plug the multi-meter

I will remeasure the voltage for the white wire for the pins in and out

I redid the test, I can confirm the value that I have on the white wire while retracted = 0.103V
However when I boot, after the "testing", while retracted I have 3.20V…

Is there any test that I could do on the board itself to validate that I just don't have a damaged board? I already had to reweld 2 pins on this board. I visually checked pins 1-2 & 21, they seem fine... I am afraid to cause damage if I go check anything with the multi-meter without proper instructions...

Thanks you

Try P1 instead of P5 in the M558 command, in case it makes a difference.

You say you added the proper G31 command in your config.g but in the file you showed, the G31 is missing its P25 parameter, which is required to get the BLTouch to work.

Since you can measure a voltage between 0.1 and 3.2V on the white wire, it means the 3.3V trace was correctly cut.

Out of curiosity, which pins did you have to reweld on your Duet? Was it the Zprobe input?

If the Zprobe input is damaged on your Duet, you could always use probe type 4 or 6 to use the E0/E1 endstop pins instead.

Sorry the P25 was an oversight, I redid the complete settings. I added the correction on the file and in the above thread.

for the rewelding, no it was for the E0 hotend

I changed To P1 in the M558, should I change any other thing?

M558 P1 X0 Y0 Z1 H5 F100 T2000
G31 X30 Y18 Z1 P25 ; Set Z probe trigger value, offset and trigger height
M307 H3 A-1 C-1 D-1

Automatically the value in Z-Probe dropped to 0 and when retracted at 990.

I see this as good news!!!

I sadly did not have the time to do the proper testing (multi-meter test, homez & homeall)

Thanks you

dc42

Looks good! Although I don't understand why P5 in the M558 command isn't working, because the pullup resistor that P5 activates is high value, around 100K. I still suspect a bad connection at one end of the white wire.

I suggest you choose a P parameter of about 100 or 200 in your G31 command instead of 25, to give a bit more noise immunity.

Nylkos

Good news… it works, the P1 did the job.

However I had to go with the deployprobe.g and retractprobe.g, the M401 & M402 didn't work with Probe Type 1.
All I did was change to these

M558 P1 X0 Y0 Z1 H5 F100 T2000
G31 X30 Y18 Z1 P200 ; Set Z probe trigger value, offset and trigger height

and Replace M401 by M98 Pdeployprobe.g and M402 by Pretractprobe.g

Thanks you for your help!

dc42

Which firmware version are you running?

M401 and M402 work exactly the same regardless of the probe type you configure. Although M401 might not run the deployprobe file if the probe is reported as being deployed already, for example because you deployed it using M401 and then retracted it without using M402.

At first I thought that it was my files, so I used the ones from Fulg (slightly modified, bed size, only one tool…), value always remain at 1000 can't get 0...
I added the I1 at the M558 P5, M401 & M402 was working values always at 0...
Removed the I1 and changed the M558 P5 to M558 P1 & M31 P25 to M31 P200, the values are now good but M401 & M402 had to be replaced by P98 Pdeployprobe.g & M98 Pretractprobe.g

Everything works, now getting ready to calibrate the BLTouch.

Once again thanks you all for your assistance.
