@dc42

Thank you very much for replacing my sensor.

How will this be handled? Do i get a new one from my dealer and my dealer will get credit?

@norder

Thanks for your help.

I have already turned off the light. Without success.
Also reduced the driving speed to 5. Without success.
I cannot set a trigger value. But since the sensor does not run in analog mode, that should not be necessary. It acts as a pure switch (led lights up twice when switched on).
I described my problem here, because I assume a hardware failure of the IR probe. My dealer is already informed and asked me to ask here in the forum for possible sources of error before sending it back, to make sure that the IR-Probe is defective.

Danke für deine Hilfe.

Ich habe bereits das Licht ausgeschaltet. Ohne Erfolg.
Auch die Fahrgeschwindigkeit auf 5 reduziert. Ohne Erfolg.
Einen Auslösewert kann ich nicht einstellen. Da der Sensor aber nicht im analogen Modus läuft, sollte das auch nicht nötig sein. Er fungiert als reiner Schalter (Led leuchtet zweimal beim Einschalten).
Ich habe mein Problem hier beschrieben, da ich von einem Hardwarefehler des IR-Probes ausgehe. Mein Händler ist bereits informiert und hat mich gebeten vor dem Rücksenden hier im Forum nach möglichen Fehlerquellen zu fragen, um sicherzustellen, dass der IR-Probe defekt ist.

I have the IR-Probe (https://www.dold-mechatronik.de/IR-Probe)

When did you purchase it?

Last week. From here: https://www.dold-mechatronik.de/IR-Probe

@herve_smith

Thanks for your info. That is of course interesting. Which print bed did you have the problem with?

Can you give me a link to the dockable probe?

Since I am using the probe also to home z it is unfortunately inevitable that the sensor triggers too early.

@phaedrux

Yes I also tried it with a sheet of paper with the same result. The sensor is free of filament or other foreign matter.

I still suspect the sensor is defective otherwise the reviews on the net would not be justified.

This inconsistent behavior has been since the beginning. I especially do not understand that it sometimes triggers so early (8mm too early) that it can not home z. The next time you try, it may work again...

There are no bright stray lights in the area that could interact with the light.

Is there any experience with GRP (GFK FR4) plate?

I am using klipper and set the probe like the last picture in my first post. I am using the probe in digital mode. The led is blinking two times on power up.

I use a GRP FR4 plate, but have already tried it with a piece of paper. Is GFK FR4 not suitable?
Is somebody else here using the ir probe with gfk bed plate?

If the accuracy runs through, the range is very high in my opinion.

I wonder if the IR probe is defective, since it also triggers well outside the actual measuring point.

@phaedrux

Here is a close up.

I have the IR-Probe (https://www.dold-mechatronik.de/IR-Probe) installed in my good old JGAurora A5 with MKS Gen L V1.0 board. It is installed on the Z+ stop. It works as far as it goes, however it usually triggers erratically well above the trigger point (about 8mm). I can not reproduce it. So currently I can't print because the home process usually can't be done. Also the bed leveling usually aborts. I use GFK FR4 as the print bed. But I have also tested other surfaces. For example, used a sheet of paper for testing. I have already invested several hours and ruled out everything, so I suspect that the IR-Probe is defective. Or do you have another idea what I could have done wrong or can try.

Thx for your help.
