Configurator BLTouch bug

[RafB]

Hello,

I do not understand what I need to set as gcode version 1.21 RC3? I followed this tutorial, but his M558 is in P5 because he did the tutorial in 1.20.

I mix the brushes on config.g, Bed.g and the boot scritp.
When I apply his tutorial perfectly, I have my bltouch who has strange reactions.

1 / The BLtouch does not deploy when the machine is turned on, not all the time. I solved part of the problem by following this tutorial but from time to time the bltouch does not come out at startup. Just run the reset command and I can go on a self-calib.

2 / The auto calib is perfect when we look at the visual grid at the end of the auto calib ()

3 / When I start my impression, the head remains about 1mm above the bed, although G31 P25 X0 Y20 Z0.627 corresponds to the value found by the command G30 S-1.

4 / My startup script may not be correct, but at each print launch, a self calibration is started. I would like not to have the self-calibrated with each impression but rather when the temperatures of the room changes or at the change of type of filament.

So I am blocked (so not far from printing!) And I can not find the info that will make me advance because my English is very bad to my great despair!

If anyone has a little time to steer me and or solved my BLtouch problem ...

thank you in advance

@rafb, release candidate versions of firmware should not be used once the corresponding release is out. So please upgrade your firmware, preferably to the latest release (2.01). Get it from https://github.com/dc42/RepRapFirmware/releases.

[RafB]

Hello and thank you for helping me.

I updated the firmware. But now during an automatic calibration the bltouch flashes after some probing.
Self test bltouch works well.

These are the error messages that I hope you will continue to help me. Thanks

[dc42]

You should remove the two M98 commands from your bed.g file, because bltouch deployment is handled automatically if you have the correct deployprobe.g and retractprobe.g files.

[RafB]

Re,

It still does not work. I followed your advice but nothing works. From the 1st probing, the bltouch flashes.

Do you have another proposal to solve my problem?

Have you verified that the trace has been cut to enable 3.3v logic?

[RafB]

I really understand nothing.

Yes I think it's good to cut
I have 2 bltouch, and it does not behave in the same way! see video

The, I despair, can I back down version (2.01 to 1.20) easily? That way I can apply the tutorial and especially print ...
There is the option to change sensors but the IR does not seem to me well suited with a glass plate. I often use geckotek ...

It remains the options I send videos (I am bad in English and google not always very good for the technique) and I await your analysis. I thank you for that again.

A +

[Phaedrux]

The tutorial should apply the same regardless of firmware version. But if you absolutely want to downgrade it should be as easy as uploading the older firmware. You may also need to upload the older wifi server and DWC files as well. But ideally I think you should try to get it working with 2.01 due to the other bug fixes and enhancements.

I would suggest going over the wiring very carefully and checking for any loose crimps or broken wires. Check for continuity with a multimeter. Double check you are using the right pins. Recut the trace.

[RafB]

Hello,

You were right one of the bltouch had bad contact. I solved this problem.
But DC42's advice to remove M98 (deployprobe.g and retractprobe.g) does not solve the problem.
I always have the Bltouch that starts the probing and after some probing (it's random, never the same point), it blinks.

Check the Z probe reading in the web interface when the BLTouch is deployed but the pin has not been pushed up. It should be zero. If it is about 1000, then either you have not selected the correct mode in M558 (it should be P9, and you should not have the I1 parameter), or there is a bad connection between the Duet and the white wire of the BLTouch.

[RafB]

Everything works perfect for bltouch with up, down, reset and self test macros.
But as soon as I go on an autocalibration the bltouch flashes on randomly on the 1st probing.

Do not do M561 and or G32 S2 for "reset" what is already register?

What information can I give you to simplify your expertise?

@rafb said in Configurator BLTouch bug:

Everything works perfect for bltouch with up, down, reset and self test macros.

Does that mean that you get the correct Z probe reading, or haven't you checked it?

[RafB]

Sorry, I'm French and I do not understand what you mean.

It has been several times that I turn on my printer and that communication is impossible. the wifi light is lit. It is very hot in France (31 in my garage) but I have the original Tevo fan that works.

I do not understand why the bltouch works perfectly by sending the up, down, reset and selftest commands individually but when I run the auto calibration, the bltouch does some probing and can not finish the autocalibration.

I do not know what to do and I just have to hope that you will find what I did wrong or forgot to do.

I mean this:

@dc42 said in Configurator BLTouch bug:

Check the Z probe reading in the web interface when the BLTouch is deployed but the pin has not been pushed up. It should be zero. If it is about 1000, then either you have not selected the correct mode in M558 (it should be P9, and you should not have the I1 parameter), or there is a bad connection between the Duet and the white wire of the BLTouch.

Ok I understand what you mean now but google must translate poorly what I tell you.

When there is no i1 in deployprobe.g and retractprobe.g to do auto-calibration or macros, the bltouch commands do not work.

I checked all my connector and crimp (welded) to the multimeter, no problem.

After some probing, the bltouch goes up and down which makes it blink.

From your videos it looks like the probe pin is sticking. Earlier you said you had tried to repair it by taking the pin out?

Try this, put the probe into self test where it deploys and retracts the pin repeatedly and leave it running for a long while. The probe should continue indefinitely. If it gets stuck and goes into error that means that the pin is likely getting stuck. If this is the case you may need to replace the probe. The newer versions of the BLTouch are quite improved over the older style. The pins are now plastic for instance. Given the cost it may be worth just replacing it.

[dc42]

You still haven't answered my original question: is the Z probe reading shown by DWC zero (or close to zero) when the probe is not triggered?

[RafB]

@phaedrux

I launched the selt-test at 22:44 and at 22:57 it was still running. So it works well in the void.

Yes I think I have this option to buy a newer, newer bltouch that will be the least expensive. But there is also buy the complete delta kit Duet3D Smart Effector. this will allow me to be more precise from what it says on any bed surface.

[RafB]

@dc42

what is DWC?

Z-probe remains always displayed at 0 pin down, pin up and selt-test.

[RafB]

I just launched the auto calib, it was 2 probes and the sensor has increased to 1000.
