Using Scanning Z Probe with Duet 3 6HC and 3HC Expansion Board
-
Hi everyone,
I'm using a Duet 3 6HC mainboard along with a Duet 3 3HC expansion board, and I'm planning to use a Scanning Z Probe.
-
Should I connect the Scanning Z Probe to the 3HC expansion board, or is it better to connect it directly to the 6HC mainboard?
-
Is the Scanning Z Probe alone sufficient, or do I also need to use a separate Z endstop?
-
The print surface consists of an aluminum bed with a non-metallic build sheet on top (it’s a paper-like material around 0.1 to 0.5 mm thick). Will the Scanning Z Probe still be able to take accurate measurements through this surface?
Thanks in advance!

Either order is fine although you may find connecting it at the end is easier as it doesn't have CAN pass through
-
With 3.6RC2, just the SZP is sufficient for scanning and touch probing.

You should be ok

@jay_s_uk thanks
Which connection do you recommend for the Scanning Z Probe?
On which board and port should I connect the Z Probe?In the configuration tool, when I select the probe type, I can’t see an option to choose the specific port for the Z Probe. Could you please clarify how to define the correct connection?

@rkutun the new touch stuff may not have been added to the config tool yet as it's still classed as an experimental feature.

Don’t I need to use a CAN connection for the Scanning Z Probe?
Currently, I’m using the CAN port on the Duet 3 6HC to connect with the Duet 3 3HC expansion board.
Is there any additional CAN port available on the Duet 3 6HC? I couldn’t find one.
If there are any recommended ports I can use for the Scanning Z Probe, could you please let me know which ones you suggest?Thanks in advance!

@rkutun theres a CAN out connection on the 3HC. Use that.
CAN-FD is a bus so its just one continuous run
