Firmware update failure..

Helensdad

I have uprated the firmware again and tried on Duet 2 WiFi and Duet Maestro to no avail. I even used a brand new good quality USB lead. I bought it on May 24th last year so out of warranty. Do you know if it is repairable?

@Helensdad have a close look at the 4-wire cable. It’s possible there’s a poor contact, or wire pulled out of a crimp. If you have a multimeter, check resistance of each wire, should be less than 0.1ohm.

Resistance all below 0.1 Ohm, I get the same problem with the 10 way ribbon cable as well...

Just to clarify: the PanelDue screen lights up and shows all the buttons etc. but remains stuck at "Connecting" - yes?

Helensdad

Yes, that is correct, tried on 2 Duet boards, updated firmware twice, checked resistance of each conductor on 4 way cable and tried 10 way ribbon cable..

The usual causes of failure to connect:

Using RRF 3.1 or later, and not having the correct M575 command in config.g.
Mismatched baud rates. Check that both ends are set to 57600, in M575 on the Duet and on the Setup page of PanelDue.
Faulty cable, either a bad crimp or Tx/Rx wires crossed. Check the that wire colours at the 2 ends of the 4-pin cable are reversed from one end to the other.

PS - it's occurred to me that I may not have tested connecting a PanelDue to a Maestro with recent firmware, because it's an unusual combination. So if you are using RRF 3.1.x then it could be a firmware issue.

@dc42 Well, I feel a bit daft now, changed baud rate to 5700 and all is well! If my Duet has incorrect baud rate set could that be the cause of my Firmware problem?

What firmware problem is that? I suggest you start a new thread about that unless you already have.

Helensdad

@dc42 ok, apologies, I thought the two problems may have been interconnected as the paneldue went on the blink immidiately after the firmware update...interconnected

If slowing down the baud rate that much has an improvement that might indicate an issue with cabling or interference. Either way, glad you got it sorted out.
