Z axis switch with Firmware v1.19

Hi Guys,

It has been a long while. I have just updated to v1.19 (from v1.09) and use end stop switches on all 3 axis on my Ormerod1 (Duet 0.6)

I thought I had worked out all the new g-codes and had changed my config.g to have

M574 X1 Z1
M558 P4 X0

This allowed the X to home correctly and reported correct status for X,Y,Z in the M119 commend but I ignored what it now said about the z-probe being at min stop

Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop

When i tired to home Z it reports Z probe at min at start of homing and just stops.

Any help greatly appreciated..
Dan.

You need Z0 in your M558 command too.

Sorry was not in work Friday to try, thanks for the quick response. Still did not change the state of the Z probe, it seems it still will try to do bed probing as well? Any other settings it could be?

>>> M558 Z0 X0
SENDING:M558 Z0 X0
>>> M119
SENDING:M119
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop
Error: Z probe already triggered at start of probing move
[ERROR] Error: Z probe already triggered at start of probing move

Homing failed

Attached is my config.g if it helps.

Thanks,

What type of Z probe are you using, and how have you connected it to the Duet?

Hi David,

Thanks for helping me work through this.

I would have to check with a meter at work as it has been so long but if recollection serves it is a normally open micro switch. It is connected to the E0 endstop header on the duet. As I say an M119 responds with

Z: not stopped

If I hold the switch down it responds with

Z: at min stop

If I leave the config as default then pressing the switch does not change the M119 response but the Z probe read out also says not stopped. After the M574 and M558 Z probe changes to min reached and stays like that.

Cheers,
Dan.

Dan, if it's a Z endstop switch not a Z probe then you should connect it to the Z endstop input and change your homing files to use a switch not a probe. See [duet3d.com].

Thank you.

It was indeed the homex.g and homeall.g that needed updating.
