BLTouch V3.0 Reassemble

; Miscellaneous
M501 ; Load saved parameters from non-volatile memoryI assumed you had a config-override.g since you have an M501 in your config.g to load it. It's fine if you don't have it thought. It just means you haven't used M500 to save any PID tuning values.
-
@Phaedrux ah yes since I typed my values directly in.
So since H3 doesn't work is that a bigger problem?
-
I'm still inclined to think it's a wiring issue.
Can you make up a brand new very short wiring harness to test with?

I have had many instances lately of the push pin breaking off many times as well as unresponsiveness from the BLTouch itself.
It could also be a bad probe. Perhaps time to get another to try?
-
@Phaedrux well I do have three BLTouch, two V3 and one version 2. I'll try some wiring and see what I get.
-
can you post a picture of the wiring on the duet?
in the first post you showed heater pin 7
-
@Veti the first post was what started off using. For troubleshooting purpose Phaedrux recommended using heater 3 to test.
-
@Phaedrux turns out I have two bad BLTouch V3.0. Wired V2.0 up to heater pin 3 and new wires and it started the self test at start up. Attached V3.0 to the new wires on heater 3 and nothing, but it did turn on. Put on the old wires and V2.0 works just fine and again V3.0 nothing. Too bad they only have a 30 day warranty on them.....

i have moved away from the bltouch and use this https://www.thingiverse.com/thing:3303618 now.
really happy with it and its working consistently (no dropped pins while printing) -

Looking at the high percentage of bltouch threads in this forum, I just wanna confirm @Veti’s statement: Z-probe designs like his one or this here are really good for happiness. Following the inherent principle, I built a similar probe and never had any trouble since then. If you know how to attach a cheap servo to the Duet, there’s definitely no need to increase the number of such threads towards infinity

@infiniteloop I agree. Bltouch sounds great on paper but the headache they are to put together and just to get working correctly doesn't justify in my opinion. My second printer I'll be looking at doing something different than BLTouch and will look at this design.
