Short to the metal work?

Component A is a 1uH inductor in early versions of the Duet WiFi. In later versions of the Duet we use a ferrite bead instead, part number MFB-201209-0011PW . Component B is a Schottky diode, part number DB2W40300L.

I suggest you measure the voltage at the junction of the 10uH inductor (the grey square marked 100) and the 1uH inductor. If there is 5V at that point, then you should only need to replace component A. Otherwise you will also need to replace the diode and the square black chip U3.

@nightreaver said in BLTouch Self-Triggering during multipoint probing:

@dc42 Can you confirm that M558 A has upper limit? When I set it to 15 with works okay, when I set it to 50 it seems like the limit goes down to A2 or something. Is this right?

From the Bug Fixes section of the firmware 2.03 release notes at https://github.com/dc42/RepRapFirmware/blob/dev/WHATS_NEW.md:

Setting M558 A parameter to anything >31 set it to 0 instead of to 31
