z probe help if possible
-
Hi,
What Duet hardware are you using? What version of the firmware?
What is the part number of the "z probe"? I cannot make it out.
Why did you add that diode?
Thanks.

Hi again
With the bat diode you would need a pullup as far as I can remember.Try this:
M558 P8 C"^io3.in" H5 F120 T60000 -
I don't know what you mean by "facing resistor"--> Facing probe?
" The BAT85 diode should always be wired with the black band toward the probe, not toward the MCU."Now, the input of the Duet 3 board is 30 v tolerant so you wouldn't really need the diode. But I leave that to other to answer as I don't want your board to burn if I'm wrong
It should work with the diode and a pullup.
Test the probe first just by connecting power to it and see that the led turn off and on when you put metal near it.

Board: Duet 3 MB6HC (MB6HC)
DSF Version: 3.4-b6
Firmware: RepRapFirmware for Duet 3 MB6HC 3.4.0beta6 (2021-11-06)The BAT85, this is from the voron 2.4 build. Its on the BOM, and some of the sights to purchase this z probe are selling it with the BAT85 preinstalled. This is a PL-08N2 probe.

@frnknstn The way i have it now it LED is on at all times and when i get close to metal it does go off
-
@frnknstn Sounds good to me
-
@gixxerfast Should i do the pull up if it is signaling as is?
-
@frnknstn Yes, that's how I remember I had it working too, before switching to the Klicky probe.
You can always check it before you try to use it for real by the "near to metal" thing
-
@gixxerfast cool, ill test it out. I will be switching to Klicky soon to as soon as this beast is up and running properly.

The Duet 3 hardware has built-in pullups - you do not use the ^ character.
I would remove the diode.
Frederick
-
@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?
Frederick
-
@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
