Bltouch setup need help

@Elvis0z to be sure: your BLtouch is right and behind the nozzle?

Elvis0z

Yep right and behind

JoergS5

@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.

Elvis0z

I cant go down on the z
As it won't home z
Should I just manually move the hotend to the bed

JoergS5

@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.

@Elvis0z @Phaedrux is here to the rescue! (I hope)

Error: Z probe was not triggered during probing move
Error: Homing failed

Double 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

Elvis0z

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

Elvis0z

No I replaced it with a v3.1 that I had

Elvis0z

If I send command M401 and M402 it triggers

Phaedrux

You mean it deploys and retracts?

When you send G30 does the pin deploy?

Elvis0z

I get this error when sending G30

G30

Error: G30: Insufficient axes homed for bed probing

Elvis0z

@Phaedrux

Yep deploys and retracts that is for the M401 M402 commands

Phaedrux

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?
