Duet3 Homing failed

[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.

@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.

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?

[Hammad]

@jay_s_uk I didn't remove the board from the housing. I just got the board and 3 1XD Modules for a big 3D printer. The board arrived like a month ago. The issue with BOSSA was just an issue because I misunderstood the Firmware process. I erased the Firmware by bridging the erase on the board. There is no wiring issues and everything is built according to the documentation.

[Hammad]

@jay_s_uk I only have the CAN cables and the 24V cables. nothing else. The motors are connected to the 1XD Modules.

[jay_s_uk]

@hammad one for @Phaedrux or @dc42 to comment on then. in the mean time use it with USB power applied

Or else the jumper to enable the on-board 5V regulator is not int the correct position. @Hammad, please check it against the wiring diagram.

[jay_s_uk]

@dc42 forgot about that! Good shout

[Hammad]

@dc42 Thank you so much. This was actually the Problem.
