z probe help if possible

@frnknstn said in z probe help if possible:
@gixxerfast Should i do the pull up if it is signaling as is?
The Duet 3 hardware has built-in pullups - you do not use the ^ character.
I would remove the diode.

@fcwilt no problem ill remove it and see.
-
@frnknstn removed and removed. LED on probe is on and metal near it shuts it off. Im assuming this is good. Now i just have to get the config right. thank you guys for your help
-
EDIT: Fantastic, I learned a new thing here. No explicit pullups required with the Duet 3. Changed all my configs now.
I need to go through my config I'm using '^' pullups everywhere
So, I don't need to explicitly enable internal pullups on the Duet 3 hardware?
For example when I have a ground to in switch endstop?

@gixxerfast man, I never thought I would get this much help at setting up my printer and learning what's going on. I am very appreciative
-
@frnknstn now if i can get help with my config i would love it.

Here are the schematics for the inputs 0 to 8. The first image shows the basic circuit. The second shows the input protection provide.
You can find the Duet 3 6HC schematics here:

What kind of help do you need?

@fcwilt So, when i home all for example, X homes properly, Y homes properly, Z does everything until it gets to the probe inputs. It goes to my first probe point then instead of going down to test, it goes up real slow and dont stop unless i trigger the probe.
-
@frnknstn I think you need to post your latest config.g, homeall.g and homez.g

@frnknstn In homeall.g I don't see a G30 to use the probe also you want to go absolute to Z = -200. I might have missed something.
What happens when you just run homez.g? (turn you steel plate upside down to protect the pei)
Is your Z going in the right direction?
Also, you don't have a Z-switch (nozzle probe) do you?
-
@gixxerfast no, i tested homez again, it does what i said previously.
-
@frnknstn another thing as it is slowly rising up it looks like the left rear motor is moving a little faster than the rest
-
@frnknstn said in z probe help if possible:
@gixxerfast no, i tested homez again, it does what i said previously.
Yes, but if you manually run Z up and down with G1. Does it go in the expected direction or do yo have to invert the motors?
Also, your probe config is a little bit of a mess. Have a look here and go through your config.g and homeall.g and homez.g and try do make it look a bit more like this one.
Skip the pullups in the example config though -
@gixxerfast imy z does look backwards. +10 brings the gantry down to the table. -10 opposite. I will switch this to start
-
@frnknstn Because, your homing config looks like a mix of endstop config and probe config depending on which file you look in. Also in config.g you have, as I see it, a lonely G31 down by the heater definitions.
So, it's better you take a grip on it and follow an example, like the one I linked, and go from that one.
