@rmilyard use putty/YAT and as a serial connection

would be good to grab an output of M122 before your send the above commands (you can do that over serial too)

Thanks all for help! It was combo that my old harness had wire issue and these 2 fans needed zinc washer. Seems like fan working now.

I think I have it going now. Looks like wire wasn't going into the duex heater all the way. I was able to jam in it and now heats up.

@rmilyard the Pi has very specific power requirements. In particular, the 3.3V regulator on it has quite a high dropout voltage, so it really needs a 5.2V power supply, not 5V. Added to this, the ribbon cable connecting the Duet and the Pi is not really suited to carrying the amount of current that the Pi 4 demands, so there will be some voltage drop in it.

The 6HC board was originally designed to be able to power a Pi 3 with very little attached. The Pi 4 draws more current than the Pi 3, and if you add a HDMI display then you may exceed the 3A rating of the 5V external power capability of the MB6HC.

For these reasons, we recommend that you use a PSU specifically designed to power a RPi 4 and whatever accessories you power from it.

@rmilyard See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_3HC_Hardware_Overview#can to set the CAN address and check the hardware connection.

The DIAG LED between the two CAN connectors indicates CAN bus state. When the expansion board starts up this LED will blink rapidly. If the expansion board is connected to a main board running compatible firmware, the LED on the expansion board will switch to blinking synchronously with the main board LED once time sync has been established across the CAN bus.

To check they are talking, and that both 6HC and 3HC are on the same firmware version, see https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_3HC_Hardware_Overview#commissioning

@rmilyard I haven't tried the SSH file in a while in favour of the advanced settings of the Raspberry Pi Imager but I'd expect it should still work. If you are on the stock DuetPi image, you can enable SSH using an M-code as well. You can send this using the console:

M586 P2 T1 S1

@rmilyard If you have the 7" PanelDue with the addon board that mounts via header pins, that the correct firmware.

The addon Board: https://www.filastruder.com/collections/electronics/products/paneldue

7i: https://www.filastruder.com/products/paneldue-7i

move the nozzle as close to is as possible.
then measure the distance from the nozzle to the center of the leadscrew.
add that to the nozzle position and that's your leadscrew location.

Send M122 and report the results please.

@rmilyard The laser version is a bit more limited in the materials you can use with it. From the product page:

Note: The Laser Filament Monitor is sensitive to the filament type used: it has proved less senstive to PETG of certain types. Please read the documentation for more details.

The magnetic version is more adaptable, but more expensive. Unfortunately, I don't have either of them! You'll have to ask for feedback from other users which they prefer.

@rmilyard said in Question for you guys about Duet 2 or 3:

So for the XY axis should I switch steppers out to 0.9 steppers and if so which would you guys suggest?

have a read of this
https://www.thingiverse.com/thing:3382718
there are also stepper driver recommendations.

Can you be more specific?

First steps would be to do some troubleshooting, and to do that we need more information.

@rmilyard said in Some new build Duet 2 Wifi questions:

When it comes to 1.8 and 0.9 and microstepping etc I am pretty green in my understanding.

here is a very detailed analsys of 1.8 vs 0.9 for prusa printers.

Take a look through this series of guides.

It's specific to the Ender 3 and Duet Maestro, but it's generally applicable to any i3 cartesian printer and Duet board. It starts with wiring and moves through using the web configurator to get a config set and then commissioning and calibrating the printer. It'll give you an idea of how to begin and has links to further documentation you'll need.
