@Tinchus After checking with @dc42, it seems the BMP280 is not supported, only the BME280 is. If you want it supported, add a request in the 'Firmware wishlist' category.

@o_lampe Totally different board, totally different ports/pinouts...

@CNCModeller this might help you https://docs.duet3d.com/en/User_manual/Connecting_hardware/Power_choosing

@elena thats sounds nice i am waiting for new cable then i am going to try that.

@dc42 Hi, yes I am powering with 24V.

The data-sheet to my valve is here: https://www.landefeld.de/cgi/main.cgi?DISPLAY=artikel_datenblatt&param_0=313681&param_1=en
I do think the ground is mainly to ground metal parts like you said, so I guess I'll just connect the ground wire to my duet power ground screw.

Thank you for your suggestion!

@dc42
Thank you, that's actually a lot of options!
The power on threshold is 4V for this SSR.
Maximum power draw is 0.6W

As I'll need 3HC board nevertheless, is it possible to run X and Y motors from 48V powered 3HC and use 6HC with 24V for the rest?
I'd not have the issue then, and also powering 12/24VDC outputs as fans and LED's would be a lot easier.

@waldekk the dozuki wiki hasn’t been updated for a long time, and has now been taken down. Use the new wiki. The pin names you want are here: https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/Duet_2_WiFi_Ethernet_Hardware_Overview#pin-names

@greenaar can you please test this with RRF3.4.5.

I am going through old github issues and note this one is still open:
https://github.com/Duet3D/RepRapFirmware/issues/565

greenaar created this issue in Duet3D/RepRapFirmware closed [Bug]: G30 does not respect K1 when K0 triggers #565

I do mean the Duet 3 main board 6HC. I will look at the methods suggested.

Thanks
Joel

@CNCModeller see this post https://forum.duet3d.com/topic/32261/duet3d-fully-assembled-duet3d-filament-monitor?_=1683051466064

@dc42 Its a bit of a tradeoff, I want to cover a range from -20ºC to 120ºC, have to compare whether a 10k thermistor would still work well on the upper end - thanks for the suggestion!

@Phaedrux figured it out. It seems when I did the wrong pid tune command it may have reassigned my heater definition. I may not have noticed because it was in the config override ? I reset the board and redid all the files on my SD card from scratch with the latest firmware. Seems to be working fine now.

@dc42 Thanks. even one 6HC is an overkill for my project. I was initially looking at 3HC and running some steppers in series. Then I realized that main boards can be made slaves and the Mini 5 is a great option for additional drives and it has the WIFI too. I think the project will end as two Mini 5 brds when all is done. Thanks.

@Proschi78 some of the infrastructure (i.e. CAN message protocols) will be in place to support this in the 3.5.0 release, but the support for LEDs on expansion boards may have to wait a little longer.

@Jiarko I'm glad you found the cause. I'll mark this as solved.

@deckingman hey no worries. Glad it’s helped a few times. Why more people don’t use them I don’t know. Schenider have quite an old model but I have been told they are releasing a new model soon. They may have already actually. They other one to look at is ECB’s (Electronic Circuit Breakers) instead of fuses. You can have alarm outputs on them when they trip so you can go figure out why and reset them

@gumby

Just to finalize the topic, I wanted to post that mixing pins from available headers worked like a charm.

PanelDue working now.

Thanks again to this community.

Cheers,

What is the correct way to connect SDSK motors to a Duet 3 6XD controller, and which pins should go where? Thanks
