Duet3 Homing failed

@hammad it has for people in the past. i've seen instances where standard USB doesn't provide enough power, especially laptops

Hammad

@jay_s_uk Thank you for the idea. Ill let you know in few minutes if this actually works.

Hammad

@jay_s_uk Thank you so much! this actually worked. It is writing the Firmware right now. It's been at 34% for a while now. I'm just glad that it connected!

jay_s_uk

@hammad one step forwards and all that

Hammad

@jay_s_uk Do you think it is normal, that it's taking that long?

jay_s_uk

@hammad no, its not normal for it to take very long. last time I flashed one the increase in % was fairly uniform and only took a minute or so.
maybe try again?

Hammad

@jay_s_uk Same thing. it gets stuck at 35%. I've tried it from a different Laptop.

jay_s_uk

@hammad not a good sign. hopefully @Phaedrux or @dc42 can comment

dc42

It might be worth trying the modified version of Bossa that I released recently. See the fork of Bossa at https://github.com/Duet3D/BOSSA/releases/tag/1.9.1a-duet3d.

Hammad

@dc42 It does the same and gets stuck at 34% of the writing process. Any other ideas? I hope this isn't the only way.

Phaedrux

Can you confirm that you have the same write options checked?

Hammad

@phaedrux Yes, I followed the instructions in the documentation. I've tried from many different PCs and cables. The board gets detected but the writing process doesn't finish. I even left it over night and it stayed at 34%. I tried older versions of the Firmware and it doesnt get beyond 34% for some weird reason.

dc42

@hammad when and where did you purchase the Duet? Which country are you in?

Hammad

@dc42 From Dold Mechatronik in Germany.

@dc42 From Dold Mechatronik in Germany.

I received the board like a month ago.

Hammad

@hammad @Phaedrux @dc42 The firmware writing worked. The issue was the powered USB hub. After uploading the firmware to the board the 5V and 3.3V LEDS stopped working.

Hammad

@dc42 I upgraded the Firmware of the Duet3 to 3.4. When the board is only connected to 24 V externally the 5V and the 3.3V LED aren't on. When I connect the micro USB to my PC it works again (the 24 V isn't connected to avoid a ground loop). now I did the trick where I tell the board through YAT that it homed and tried to move the axis and it didn't work. What am I doing wrong?

jay_s_uk

@hammad if the 5v and 3.3v lights aren't on when powered by 24v, the onboard 5v converter has died

Hammad

@jay_s_uk why would it die after a firmware update? while updating the firmware i only used the USB port as a source. When the update was done i unplugged the USB cable and used the 24V external source.

jay_s_uk

@hammad good question. its typically the result of a short in wiring. what were you doing with it prior to the bossa issues? could it have occurred during removal from the printer (assuming you did that for bossa purposes)? if not, whats plugged into it?
