Duet3 Homing failed

Hammad

@dc42 I misunderstood the instructions and bridged erase. now i cant flash the firmware because BOSSA isnt detecting the board at all. How can I solve this issue?

Hammad

@hammad The Status LED is slightly on. I can't figure out why Bossa doesn't want to connect to the board. I've followed the instructions on how to upload the firmware if the firmware was erased. It doesn't work for me. I keep getting the error "could not connect to device on COM 22".

@dc42 I measured the 5V to make sure I'm getting a stable 5V. I'm measuring just a few mV. The board is only connected to the PC using a high quality USB cable from ANKER.

The Duet3 can be quite particular about USB cable and port. Please try some different combinations. Also make sure you remove the jumper after the erase.

@phaedrux 3 different laptops and over 15 cables and still nothing. I removed the bridge from erase before resetting the board. I'm not sure what to do now. nothing seems to be working.

@hammad do you have a powered hub you can try with?

Hammad

@jay_s_uk Do you think this will solve the problem?

jay_s_uk

@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

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.

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