Duet 3 BLTouch probing issues
-
This post is deleted! -
this suggests that there is a wiring problem. maybe a bad crimp on the extension cable.
-
ill post a video of what it does on zhome
-
Im uploading a video of what the probe does as well on that side. I don't know it looks normal to me.
-
if we do think it is the wiring though i can swap it out. I'm starting to wonder if i shouldn't just go a different probe route and do away with the bltouch all together.

M558 P9 C"^io7.in" H5 R1 F120 T6000 A5 S0.02 B1 ; Define the bltouch input on io7.in
can your remove the A5 and try again
-
Same thing other than it is only probing once now instead of multiple times in each spot.
-
to me it sound like a problem with the bltouch, but non i have seen before.
is there a different probe you can test? like a capacitive sensor or something? -
i have an IR sensor i could pull off another printer if need be. That is it otherwise they are all BLtouches.
-
want me to pull it and try to set it up?
-
unless someone else has another idea, i would try the ir probe.
-
what if i just hot glue a micro switch on the bottom so it triggers? would that be the simplest?
-
@Vampora
that would also work as a simple probe -
i think i will try that. I dont really want to pull apart my other printer to get to the IR if i dont have to.
-
is there a best in class probe that is highly recommended that for sure works with this system? It has to work with a mag bed though.
-
i am personally not a big fan of the bltouch.
on my ender 3 i use this (more reliable than the bltouch)
https://www.thingiverse.com/thing:3303618the new SuperPINDA probe from prusa looks interesting.
if your bed supports the ir probe, that would be a good choice.
but first lets establish that the bltouch is the problem.

so funny thing..... i just finished printing that was going to order servos

https://www.thingiverse.com/thing:3303618Interesting, I will try one of these for something to do, and 5 minutes rooting around in a part bin yielded all the required goodies...!!!

this switch does exactly the same thing as the bltouch. All -5.000
-
even the switch gives this error occasionally
