@dc42 That's also what I expected but looking at the logs I don't see any warning.
Thank you for the insights on the warnings.

@mjseabright thanks for drawing this to our attention. The product page is wrong; only one daughter board is supported.

You could stack a second daughter board on top of the first if you run a wire from the connector on the top of it to a spare IOx.OUT pin.

@Exerqtor the IO3 pads are not intended for a connector; they are intended for a microswitch, a TCRT1000 optical sensor or a ITR2001/T or compatible optical sensor. For a Hall switch you need three pins (Gnd, IN and +5V) so a 2-pin connector that fits two of the pads would not be sufficient. However, I guess you cold use a 3-pin 2.5mm pitch socket, bend the middle pin back and solder the two outside pins to the Gnd and IN pins of the 3-pin switch footprint. You would still need to pick up +5V from somewhere.

@o_lampe said in Dual extruder orbiterv2:

@deckingman That's right. IIRC your melt chambers were connected through narrow channels which reduce the back-pressure effect. I guess the 'E3D cyclops' works the same . But a 'Diamond'-style hotend would have only one melt chamber....
As you wrote" It depends"

No, actually a Diamond also has multiple melt chambers. The brass cone sits below the heat breaks so anything inside that cone becomes molten and remains molten when the filaments are combined just before the nozzle tip. If you set the mixing ratio to equal percentages for each input, then each individual filament travels at a correspondingly lower speed (so 33% for 3 input Diamond and 20% for a 5 input). So not only do you have a greater surface are over which to conduct heat, but each filament spends longer in each melt chamber before it exits the nozzle. The net result is a vastly increased melt rate.

@bluecvbc well done! Protecting adjacent parts from the hot air - in particular, the plastic parts of connectors - is indeed a problem. In the past I have used sections of corrugated cardboard, faced with Kapton tape to prevent the cardboard catching fire. Nowadays I generally use Cold Gold tape.

@paniha yes a poor connection to a thermistor can cause it to under-read. A poor connection on a PT1000 sensor causes it to over-read.

@Schickfus you will need to select the tool that has that extruder before you can extrude.

@wdenker yes, celcius

I inverted gpio pins 2, 4 and 6 under the pi board (so no more in the ribbon cable) and solder 5v directly on it. Works like I wanted. Thx

@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
