So I powered up my Ormerod 2 today and nothing. No network connection.. I can see the board in the Arduino IDE and I can upload firmware but i get no response to serial commands over USB and the network won't connect. No activity on the ethernet connector led's. I have created a new SD card as I thought this might be the issue but nope. I have checked the board with everything disconnected except the external regulator to no avail. Config.g attached but it hasn't changed since the last time I used it so should be fine. I really don't want the shell out £99 for a new Duet.... Any thoughts before I pull the board out and go hunting for bad solder joints on the SD card... https://reprap.org/forum/read.php?340,621499,621499#msg-621499 Tue, 11 Aug 2026 10:50:31 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?340,621499,623787#msg-623787 https://reprap.org/forum/read.php?340,621499,623787#msg-623787

Still doesn't explain why I can't connect with pronterface or Simplify3D but its working.
I'm going to assume there is a dry joint somewhere on the SD card as well as It couldn't have been something I was doing wrong when it wasn't reading the card.....

Thanks all.

P.S. I'd still be happy to Beta test the New Duet Dave Crocker..... ;)]]> NeilFrazerLX Ormerod Fri, 05 Feb 2016 09:28:09 -0500 https://reprap.org/forum/read.php?340,621499,621823#msg-621823 https://reprap.org/forum/read.php?340,621499,621823#msg-621823 Fpex Ormerod Fri, 05 Feb 2016 08:11:24 -0500 https://reprap.org/forum/read.php?340,621499,621822#msg-621822 https://reprap.org/forum/read.php?340,621499,621822#msg-621822
I can connect to the board with the Arduino IDE and it is accepting commands in serial console. However it isn't reading the SD card and there is no network activity indicated.

I have tried a different SD card and the board is powered from an external supply via the 5V_PS header. Measured as 4.9v with the internal Regulator at the Expansion header. (On a 18 Year old Fluke 75 III meter).

Cat5 cable is fine.

I'm seeing 3.3v at the SD card (measured between C58 and R73) and the ethernet chip (Measured between C58 and L2).

Would I see activity on the Ethernet if the board isn't seeing the SD card?

I'm thinking a bad solder joint on the SD card connector maybe?


Ok. Update as I'm writing this. I can now see the SD card must be a loose connection somewhere or dirty contacts as I didn't do anything concrete to get it back. I can connect with the arduino IDE and send Gcode commands and I get the appropriate response. I cannot connect with simplify3D or Pronterface which is weird. I have closed arduino die so the port should be available to the system. I am still not seeing Network activity. It is not the cable or the connection to my hub as I have proved this with another device.

I'm going to get the soldering iron out and re-flow some joints.]]> NeilFrazerLX Ormerod Fri, 05 Feb 2016 08:10:32 -0500 https://reprap.org/forum/read.php?340,621499,621810#msg-621810 https://reprap.org/forum/read.php?340,621499,621810#msg-621810 Fpex Ormerod Fri, 05 Feb 2016 07:42:12 -0500 https://reprap.org/forum/read.php?340,621499,621800#msg-621800 https://reprap.org/forum/read.php?340,621499,621800#msg-621800
Your Ethernet port is a different issue. The LEDs on the Ethernet connector are driven directly from the Ethernet PHY chip and so should work even if the CPU is not running. Make certain that the cable you are connecting is properly connected to a hub by unplugging it from the Duet and plugging into a laptop or PC. If the laptop/PC gets a connection but the Ethernet LEDs on the Duet remain dark, then it is likely that there is either a power fault or an Ethernet fault on the Duet board. Visually inspect the solder connections on the Ethernet socket on the Duet - there have been cases where some pins were left unsoldered by the factory.

Always run the Duet from an external supply, and check the 5V on the Duet with a meter to ensure that voltage is correct. Powering the Duet only from the USB will often cause problems because the USB voltage is likely to be too low to run the Duet reliably.

I was running DC42 1.09m firmware and I have just flashed 1.09r. I know there were issues with a previous release. It's not the firmware! it was running fine before.

I have powered the duet both with the supplied power supply and from USB.]]> NeilFrazerLX Ormerod Fri, 05 Feb 2016 06:14:15 -0500 https://reprap.org/forum/read.php?340,621499,621680#msg-621680 https://reprap.org/forum/read.php?340,621499,621680#msg-621680 Treito Ormerod Fri, 05 Feb 2016 03:37:12 -0500 https://reprap.org/forum/read.php?340,621499,621625#msg-621625 https://reprap.org/forum/read.php?340,621499,621625#msg-621625 I am running DC42's firmware but as I said it was running fine so I don't think it is a firmware issue.

I've heard bad things about the quality of Replikeo boards so I would prefer to go with T3DP3D personally and having read that there is a new duet out soon it might be worth waiting. Or I could Beta test, Hint, Hint DC42.]]> NeilFrazerLX Ormerod Fri, 05 Feb 2016 01:23:16 -0500 https://reprap.org/forum/read.php?340,621499,621600#msg-621600 https://reprap.org/forum/read.php?340,621499,621600#msg-621600 After two broken Duets please touch the main processor carefully. If you can touch it and it is feeling some sort of warm the Duet may be okay, but if the sensor is getting that hot that you could touch it only less than 20 seconds the board is broken. You may use a board from Replikeo which is much cheaper. Actually it was something about 65$ without shipping.]]> Treito Ormerod Thu, 04 Feb 2016 23:25:10 -0500 https://reprap.org/forum/read.php?340,621499,621550#msg-621550 https://reprap.org/forum/read.php?340,621499,621550#msg-621550
Is a shorted SD card a repairable problem? I'm fairly certain this is the cause of my 0.6 failure and I'd love to know how to fix it.]]> 0x0000 Ormerod Thu, 04 Feb 2016 18:32:57 -0500 https://reprap.org/forum/read.php?340,621499,621499#msg-621499 https://reprap.org/forum/read.php?340,621499,621499#msg-621499
