Everything worked, the results are perfect.
I have exchanged all 5 BL-Touch against the Mini IR Probe and am now really happy with the workflow.
Thank you very much for the prompt and friendly support.

Hi, I finally had time to deal with the adjustable mount for the Mini IR Probe.
It fits into the screw holes for the BL touch. The sensor can be mounted on both sides to determine the distance to the Nozzle. I like to send the STL file to request. I did not manage to show pictures here
I'm just wondering what I have to adjust in the config.g and other files. I think first I delete the deployprobe.g and the retractprobe.g, since the BL touch is now gone. In the config.d I have now the following:

M307 H3 A-1 C-1 D-1; reserve pin 21 for M42 or servo use
M558 P4 X0 Y0 Z1 H3 F200 T5000
G31 P25 X0 Y0 Z1.3; Set Z sample trigger value, offset and trigger height

Can I take that for the IR probe, or do I have to change something. I think I have to adjust the value for the Z trigger. What else do I have to consider.

ok, thank you. I will print a similare adjustable mount.

@peirof:

Do you still need instructions how install mini Ir?
It's simple, all info it's in escher webpage.
The most difficult part is the physical installation, if you can print.

I can gave the system I used tomorrow.

It's simple… Even I could do it ... Suppose it's easy

that would be fine if you post the configuration. do you have a stl file to mount the IRprobe? I ordered the IR-Probes on the escher page and already read the instructions, should not be a problem. I will definitely equip a printer with it.
Thank you!!

I have finally understood everything and found the mistake that has probably already made some.
The trigger dive height was too low in the G31 command. Now all 3 printers work and I will now try to convert a Wasp3d 60100 with this fantastic Duet board.
Thank you!

Hi,

At the end, I have changed Bltouch for Mini Ir Differential Sensor.

Works great..

I have now ordered the Mini IR probes to exchange the BlTouch probes. Could you please share the necessary adjustments in the configuration? Do you have a mount for the Tevo LM? That would be really great and would help.

Hi, that sounds good. Can you share details?
I would immediately replace the BLTouch.

Hello Peiro, thanks for your help.
My problem is the BL Touch. Sorry for my english
I have 3 identical Tevo LM printer and print parts for an art project.
I upgraded the first printer with the Duet Ethernet Board and everything worked right away without any problems. Firmware is 1.8.1.
I was so excited that I immediately upgraded the other two printers with Duet Ethernet boards. The new boards had version 1.9. as a firmware. That's when the problems started. I just had the configuration of
first printer copied. That did not work, because some had changed commands in version 1.19, David pointed out to me and I corrected that, as far as I understood. But BL Touch still did not work properly.
Since I have the firmware downgraded to 1.81. I tried to use the configuration of the working printer, which also uses 1.81.
BL Touch starts normally, but touches the heating bed while probing and stays lit red. That's the same with both printers.
At first I thought that maybe some data from the config.override will be used. But I did not find this file on the SD card

@dc42:

You should upgrade the 1.19 firmware to 1.19.2.

To seen the differences between 1.17 and 1.19.2 firmware and what adjustments you need to make to the configuration files, look at the upgrade notes for every firmware after 1.17 up to 1.19.2 in https://github.com/dc42/RepRapFirmware/blob/dev/WHATS_NEW.md.

Regarding bltouch, the main change is that deployment and retraction are automatic in G29 and G30 commands. Your bed.g file must use M401 to deploy the probe near the start, and M402 to retract it at the end.

Thank you David!

Unfortunately, it still does not work. I would be really happy if someone would share a working 1.92 configuration. Then I could identify the problem.
Thanks a lot in advance
