Strange BLTouch behavior after update to 3.3.0-b3
-
@waddo10 First, update to 3.3 RC2: https://github.com/Duet3D/RepRapFirmware/releases
There's been quite a few fixes since the beta releases.I think you have a Duet 2 WiFi? Update the firmware, then send M122 and post response to clarify your setup.
Cloned BLTouch may not have the same wiring as the original, so check that first. When you send M401, and touch the pin, does it register a change in Probe Value in DWC?
This line:
M558 P9 C"zprobe.in+zprobe.mod" H5 F180 T6000 A30 S0.02
should really be:
M558 P9 C"^zprobe.in" H5 F180 T6000 A30 S0.02
zprobe.mod isn't used, and the ^ enables the pull up resistor, which may help.

Just been comparing the two BLTouche's side by side and noticed a bit of a difference on the circuit board between the two even though they are both V3.1

Tested the old and new bltouch with the updated firmware and config adjustment. Old BLTouch homes fine. New BLTouch is the same as before, Pin doesn't deploy when trying to home Z.
On the old bltouch on startup the pin probes in and out, ends with the pin stowed and output reads 0. M401 pin out Output 0, M402 pin stowed output 0. M401 and touch the pin output 1000.
On the new bltouch on startup the pin probes in and out, ends with the pin stowed and output reads 1000. M401 pin out Output 1000, M402 pin stowed output 1000. M401 and touch the pin output 0.Strange behavior.

@droftarts Do you think the old or the new one is the clone? As in ive been using a clone all along?
-
@waddo10 new one is clone, I’d say. They shouldn’t need to be inverted. Also PCB looks simpler on new one, doesn’t have notch top and bottom. Mine has the notches, and I’m sure it’s genuine.

3.3beta3
It looks like the update to RC2 failed.

Try uploading again.
Did you resolve the problem with the heightmap not loading? Where were you loading it?

FWIW, http://www.id2db.com/genuine10.php reports both probes' serial numbers as legitimate. I think there's some confusion in this discussion about which probe is new vs old, but either way, I have a new v3.1 that looks basically identical to A7X... (corner notches on PCB, no "A&T" letters on injection molded housing body), and an older V3.0 and a V3.1 that looks very similar to 9CR... (square corners, no "R" on BLTouch on PCB). I'm also very confident that mine are all genuine.
That is all - I can't really help with the main issue, but thought providing some info from my own stock of probes would at least better inform that part of the discussion (it's easy to dismiss a failure as a crappy clone, vs. a legitimately failed BLTouch, which does happen too). I'm also not saying definitively both are real, just that right now my vote would be that both are legit.

@phaedrux Well spotted. I have downloaded again and appears to have worked this time.
I am still testing at the moment, not quite sure whats going on. Using a old model i had printed which i know loads the heightmap.
Just loading the standard heightmap that mesh compensation generates. -
@mgjosh A7X is the new one i had bought. 9CR is the one ive been using for a long time and suspected was going faulty. 9CR is the only one that works with my current config. That you for your reply.
