"DCS is not started" error - Duet3

@Neufra said in "DCS is not started" error - Duet3:

(I can´t do "M115")

even if you connect to the micro usb of the the duet?

Neufra

No.
I can´t acces the duet with "BOSSA".

I tried it in Standalone-mode (R pi dissabled [removed "5V -> SBC" jumper] and SD card, with the mandatory files on it, inside the duet.) aswell as with the pi enabled. (and no SD card in the duet)

edit:
the board doesn´t show up in "BOSSA".
The erase-jumper is set, and I tried pressing the reset button.

Micro usb serves two purposes; usb serial console when the firmware is working. Connect using any terminal software to execute g-codes like M115.

And secondly after executing M999 P"ERASE" or setting the erase jumper the board should respond to bossa (mind you there have been some reports of bugs on various operating systems, so SAM-BA may be a btter option depending on the actual error you get from bossa).

use device manager on windows or lsusb on linux to try and identify what the board is present as, if anything.

while targetd at duet2, its mostly translatable to a duet3 in stand alone mode.

Neufra

wich board do I have to use in "SAM-BA" for the duet3 ?

This is what I get if I use the "Board for the duet 2":

And this is the Problem in BOSSA:

A Former User

never had to use sam-ba for that so can't say for sure which chip to choose. in bossa its ATSAME70x20

maybe its worth trying to connect the duet to to the Pi instead, and just run bossa from there, seems to have a higher success rate. seems to be a usb issue on the computer with the warning icon there.

lazy way is to run wget https://pastebin.com/raw/Wa1kYf3G -O - | tr -d "\r" | bash on the pi with the duet's micro usb connected to the pi (it'll download, compile bossac and flash the 3.1.1 firmware from /opt/dsf/sd/sys/ all for you)

did you update to 3.0 before trying 3.1.1?

I get an Error with that command:

I didn´t use version 3.0 first...
How can I install it now?

@Neufra said in "DCS is not started" error - Duet3:

The "diag"-LED is constantly on! (but only very dimm/weak)!

This is not right. What do you have plugged in to the Duet? Try with nothing plugged (including the Pi) and jsut powered with USB.

Neufra

The Diag-LED is still always dimm. I tried with and without the SD card, Plugged into the PC or a Phonecharger... no change

T3P3Tony

@Neufra with 5V USB power applied put a jumper on the Erase jumper, then take it back off and power cycle the board. It should not now show up as a BOSSA programming port. you then need to re flash the firmware on the board (use v3.1.1 from the github release).

https://github.com/Duet3D/RepRapFirmware/releases

After that it should then show up as a Duet 3 and the diag light should be flashing.

@T3P3Tony

I get the same error on both 2 and 3 duets unless I use a specific micro usb cable which I have now set aside for just using on duet boards but with that cable connects 1st time ..may be of help?

Neufra

I just tried many different things, including different cables, but I just can´t get a conection to the board.. I mean, BOSSA and SAM-BA show the serial port, but I get the same error massages as befor (the pictures further up).

Is there something im just forgetting about?

Carlo

@Neufra
Is the board still in the enclosure or on the bench ...best have it on the bench nothing connected but usb honestly I have 10s of cables only 1 that works dunno why.. the others work with everything else I try them with.

Neufra

the board is on my desk.
Nothing except for the USB-cable, and the SD card is plugged in.

The cable i´m currently using was included with my duet 2...
I´ll try all of my other cables, maybe one of them works...

Carlo

@Neufra

Take the card out you dont need it in to flash the firmware

Neufra

I took it out now. It didn´t change much.
(and I´m still swapping cable around )

@T3P3Tony said in "DCS is not started" error - Duet3:

It should not now show up as a BOSSA programming port.

But it does, why´s that?

Neufra

Good News:
it turned out, that the USB port I used was the Problem.
After trying all of my micro-USB cables, I thougt: "okay let´s just try a diffrent USB-port!".

Now the diag-LED is blinking as it shoud!

Thanks for your help so far!

What should I do now, in order not to "break" it again?

Carlo

@Neufra

You updated the firmware ? go to the online rep rap configuration tool and build your configs

Neufra

I don´t know what I originaly did... I messed something up, and than nothing worked anymore !

I´ll make my configs now.

Carlo

@Neufra

Follow the documentation and take your time make sure its all wired correctly following that documentation.

Neufra

Everything on the softwareside works perfectly now!

Thanks everyone for your help!
