@dc42 said in PINDA Z-Probe Configuration: The reading needs to be around 0 when not triggered (no metal under the probe) and 1000 when triggered. Try removing the i1 parameter from your M558 command in config.g. well, that did the trick. Thanks a lot. It's not as easy to work with Duet, being used to Marlin for years...

sorry i just realized how the setup is one. are the switches NO or NC? i would try to wire them in parallel and use M558 P5 they will need to be connected to the z probe port. but a construct would allow the printhead to move. this would not be beneficial for the print quality.

Thanks, @oliof !

I got a document today detailing the setup on Duet today from hotends.fr. I will see whether I can extract the pertinent information and add it to the wiki.

If the problem occurs only while the fan is powered (not when it is spinning down), you could try setting Z probe type P9 in your M558 command, as if you were using a bltouch. That will cause the firmware to run deployprobe.g and retractprobe.g for each individual probe move. You could turn the fan off in deployprobe.g and on again in retractprobe.g. The Smart Effector only "hijacks the fan power" to power the illumination LEDs.

I tested it within several ways, which with bed compensation and it works great. Thank you to @dc42. You can mark it as solved.
