Fly-SHT36 Max V3 RP2040 Based CAN-FD Toolboard

[jay_s_uk]

I am pleased to announce that the RRF compatible Fly-SHT36 Max V3 is now in stock at https://s.click.aliexpress.com/e/_DF3K3Nz
The toolboard brings a few additional features over the Fly-RRF36, which are:

• Compatability with both Klipper and RRF on the same board
• An LDC1612 has been added which provides scanning probe support
• A CAN out connector has been added to allow additional devices to be added or to wire the toolboard as part of a CAN chain (rather than as a stub)
• Comes with a MAX31865 installed for PT100 support (It was an additional feature on the Fly-RRF36) with easier mode selection
• Switched from an LIS3DH to an LIS2DW for compatibility between RRF and Klipper
• comes with a new type of moulded cable

Documents will be on the teamgloomy wiki in the next few days

@jay_s_uk and all others

Hello,
I've now just ordered this board:

Can I simply connect the Fly-SHT36 Max V3 to my Duet 3 6HC, or do I need to flash some firmware first so that it's recognized by my Duet board?
Can you also tell me something about the settings for the LDC1612 (the Z scanner)? So, what scanner type do I need to select in the config.g file?

Thank you for your help.

@CrazyCreator it needs flashing prior to fitting along with ensuring the dip switches are in the right position, all the info is here -

I use this board on a XOL toolhead, watch out for the ribbon connectors I found them quite tricky!

[jay_s_uk]

@CrazyCreator the scanner is the same as using the one attached to the Duet SZP and Duet Roto toolboard, so setup is the same
I've just started using touch probing in 3.6RC1 on my VzBoT using this exact toolboard

@jumpedwithbothfeet and @jay_s_uk Thank you for the answers, but just to be sure, I'll ask again:

Do I connect the SHT36 to my Duet3 6HC or Duet3 3HC via CAN and then install Duet3Firmware_SHT36MAX3.uf2 via DWC upload, or can I simply send M997 B124 via the console?

[jay_s_uk]

@CrazyCreator you would initially have to flash the firmware via USB and then connect to it via CAN. Subsequent updates are done by DWC. Info on the wiki that was linked to earlier

@jay_s_uk
I've now connected the SHT to my Mac and have a normal USB drive there... I simply copy the Duet3Firmware_SHT36MAX3.uf2 to it and that's it?

Is it supposed to be that simple?

[jay_s_uk]

@CrazyCreator that's it. Nice and simple

[CrazyCreator]

@jay_s_uk
Wow... How cool is that?

Two blue lights glow continuously, the bottom one flashes. I think that's how it's supposed to be.

Ok... Then I'll connect it and get back to you when it comes to the entries in the config.g.

[jay_s_uk]

@CrazyCreator that's correct. The light will flash fast until you connect to a mainboard. It'll then flash at the same speed as the mainboard

[CrazyCreator]

@jay_s_uk
Mmm... Actually, everything looks fine; the SHT is displayed in the CAN Manager.
But M997 B124 reports an error.

[jay_s_uk]

@CrazyCreator if you've not loaded our firmware through DWC, M997 B124 will show an error.

Looks like its working fine though. That's good news!

[CrazyCreator]

@jay_s_uk
Ahhhh ... I have to upload the firmware that I previously loaded onto the USB drive again via dwc?

[jay_s_uk]

@CrazyCreator no, theres no need to run M997 B124.
Next time you update, it'll do so automatically and it'll ask you to update.

M122 B124 will show you that all works well

[CrazyCreator]

@jay_s_uk
You mean the update with terminal and sudo apt update && sudo apt dist-upgrade?

[CrazyCreator]

@jay_s_uk

I think it looks good

Thank you

[jay_s_uk]

@CrazyCreator ah, you use SBC mode. You'll have to manually upload the binary each time you want to update

[CrazyCreator]

@jay_s_uk
This means, whenever there is a RRF update I have to update manually with your Duet3Firmware_SHT36MAX3.uf2 downloaded from github and uploaded then via the DWC?

[jay_s_uk]

@CrazyCreator correct

[CrazyCreator]

@jay_s_uk
Many thanks for your support ... i think i write the next days for config the new z-probe-scanner
