Probe problem.

adavidm

I had the exact same symptoms the other day. It turns out I was using the wiring diagram from the production Duet with my beta (white) board. The probe connection is inverted between the two.

Could that be a factor here?

I have no power on the probe volt socket on my duet.
Do I need to enable it or is it always on?

It's always on. Check that you have the right connections - see adavidm's post. The pins are also labelled on the underside of the Duet.

Somehow I manage to read the pinout mirrored but its corrected and it works as it should from a power on perspective.

Are the only FW changes needed those that I made below? Should Z1 still be in M574?
Have tested to put my hand under the probe when homing Z but it does not stop but the LED turns red… Doing a safe test here..

Now I have set it exactly as in https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer

M558 P1 X0 Y0 Z1 H3 F200 T5000 R0 ; smart IR Z probe, used for homing Z axis only, dive height 3mm, probe speed 200mm/min, travel speed 5000mm/min, no recovery time
G31 P500 X11.0 Y0.5 Z1.65 ; set threshold and offsets

it still does not stop..

M558 should be P5 not P1

Loffy770

The P value on Z probe reacts and output 538 when I hold my hand so I assume its the configuration I need to fix…

Loffy770

P5 but on the Wiki it is clearly stated that it should be P1 for a IR probe.

Dougal1957

Yes mine is P1 as well and works

iDevelo

My fault I was thinking of a different kind of setup!

Loffy770

Could you please post your config.g Dougal?

Dougal1957

Are you on a delta

Ok, I have a cartheasian.

Loffy770

Do I need to make any changes to Bed.c HomeZ and Homeall?

iDevelo

What's the contents of homez.g ?

Loffy770

Its working now, took awhile but it all good now.
