Duet 3 BLTouch probing issues
-
I started out with 3 and some other that had working configs with the same printer use 4 i guess. I am confused on that one as well.

Any why are you measuring 4 points when you only have 3 screws?

try removing this line
and adding G28 ; homelike the guide says

Ill give it a shot.
-
Ideally, you should be aiming to probe close to your Z screws as that's where the adjustments take place.
-
swapping with the g28 still has the 4th probe missing
G32
Error: Z probe was not triggered during probing move -
should i change it back to 3 point to try to figure this out?
-
I would change back to 3 points.
Just make sure they're in the same order as your M671. So front left, front right and rear middle -
with the 3 point i still get this:
G32
Leadscrew adjustments made: -5.000 -5.000 -5.000, points used 3, (mean, deviation) before (-5.000, 0.000) after (-0.000, 0.000) -
Can you post your homeall and homez file?
-
homez:
; homez.g
; called to home the Z axis
;
G91
G1 Z5 F800 H2
G90
G1 X182 Y118 F2400
G30
G1 Z2 F200
homeall:
M98 P"homex.g"
M98 P"homey.g"
M98 P"homez.g" -
I can't see anything in there that would cause the issue.
Could you reboot the board and run the probing again?
Could you also post the updated bed file? -
Updated bed.g:
M561 ; clear any existing bed transform
;G1 Z5 H2
G28 ; home
G30 P0 X2 Y2 Z-99999
G30 P1 X2 Y229 Z-99999
G30 P2 X240 Y116 Z-99999 S3
G1 X0 Y0 F5000 ; move the head to the corner (optional) -
Rebooted, ran g32:

G31 X-30 Y0 Z0.75 P25 ; Set the offsets for the bltouch
change to P1000
P25 could be triggered by interference. -

I just want to make sure..... does anyone think it is the bltouch not being v3.1? I'm debating ordering one since I don't have one, but my gut tells me that is not the issue.

M558 P9 C"^io7.in" H5 R1 F120 T6000 A5 S0.02 B1 ; Define the bltouch input on io7.in
can you change the H5 to H6 and see if the result changes?
-
I actually just tried bumping it to 10 and this is what I got.
It just changes everything to -10 instead of -5
M98 P"0:/macros/Probe_Test"
G32 bed probe heights: -10.000 -10.000 -10.000 -10.000 -10.000 -10.000 -10.000 -10.000 -10.000 -10.000, mean -10.000, deviation from mean 0.000 -
this suggests there is a problem with your bltouch.
how many probing of the bed does it actually do when you run the macro?
-
It does 10
-
is there an error in the console?
this suggest that the bltouch is already triggered.
whats the z value in the ui?
