@Elvis0z to be sure: your BLtouch is right and behind the nozzle?
-
Yep right and behind
-
@Elvis0z are you sure G31 Z is 0? This would mean the BLtouch triggers when the nozzle touches the bed.
Please recheck steps 5-7 in https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_height . You could trial and error some values for Z also... (Z positive) - I would do that
I don't see other problems, I would only remove the + signs from
G31 P25 X+41 Y+10 Z0.0
they will probably be interpreted correctly, but I didn't see + signs in the examples, so to be sure, I would remove them. -
I cant go down on the z
As it won't home z
Should I just manually move the hotend to the bed -
@Elvis0z you can of course move Z carefully down with the small G1 Z movements (+Z0.1 etc) until you have the famous one-sheet-paper-distance, then say G92 Z0 to set 0 position. But this is no general solution. There must be a reason why it is not working as expected.
Maybe someone other has an idea what's wrong. -

Error: Z probe was not triggered during probing move
Error: Homing failedDouble check your white wire.
M558 P9 C"^zprobe.in" H5 F60 T6000 A10 R0.5
You can try removing the^in front of zprobe.in -
Thanks heaps hey. I'm futher ahead than I have been. At least its moving and the probe works with M401 and 2. That did not work befor

Hey guys need help to set this up its a v1.0 bltouch.
Is this a version with the trace to cut or does it come with the resistor? It's been a long time since I've seen anyone with a V1, so I'm wondering if it matters in this case. If it's a new Duet 1.04 it can't be hurt by 5v, but perhaps there is something in the BLtouch that will not trigger. If removing the ^ and checking your white wire is fruitless, maybe look into the trace/resistor
-
No I replaced it with a v3.1 that I had
-
If I send command M401 and M402 it triggers
-
You mean it deploys and retracts?
When you send G30 does the pin deploy?
-
I get this error when sending G30
G30Error: G30: Insufficient axes homed for bed probing
-
Yep deploys and retracts that is for the M401 M402 commands
-
Ok home X and Y first, move the print head to the center and then send G30. Does the pin deploy? Does the Z axis move? If you touch the pin does the Z axis stop?
-
@Elvis0z said in Bltouch setup need help:

Yep deployed and red light went out and got the error
Error: G30: Insufficient axes homed for bed probing
-
@Elvis0z please remove
M307 H3 A-1 C-1 D-1
this not valid in RRF3 any more.Edit: this is the source: https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_M307

@JoergS5
Yep removed -

Just to make sure, the files you are editing are in the /sys folder, right?
