USB or Network

I have just swapped out the Duet board as the 12v to +5V was not working (thank you Ian for such speedy service), and on the new one, after updating the firmware to latest version I can connect via USB or via Ethernet but not both together.

Has anyone any ideas?

Hi Danny, when you say "not both together", is that Arduino serial monitor + network, or Pronterface + network? Are you using the same host computer and network connection as before? Are you powering the 5V from the ATX supply, or from USB?

Hi dc42

Powering via a USB hub at present, It's Pronterface and Ethernet, serial monitor seems to work OK.
Pronterface gives this error message 'could not open port COM12: [Error 2] The system cannot find the file specified'

When I get that message (assuming that COM12 really is the correct port number), I find that I need to disconnect the USB cable (do it at the host end, unless you know that the USB socket on the Duet is properly soldered on the board) and reconnect it before Pronterface will connect. Obviously this means you need to be powering +5V from the ATX supply (i.e. JP9 installed), otherwise the Duet will lose power.

You may also want to try my modified firmware here which fixes some network issues and (in conjunction with a patch to Pronterface) gets printing over USB working properly.

PS - and of course you need to close Arduino IDE before you can connect Pronterface, otherwise Arduino IDE owns the port.

Brilliant..

Not being good at python I had opted for the windows pronterface install, but now switched to the python one and surprise, it works. I'll also try all your mods.

Thanks for all your work on making the Ormerod work. It's will be great when there is a simple single install that just works. Uploading firmware and hunting through forums is not the way a product should be made to work.

@DANNYP200: There's no real difference between the way the pre-compiled and Python version of Pronterface communicate with the Duet board. They are both serial monitors, just like the Arduino IDE Serial Monitor. I expect that what was happening is that the COM port was changing on you. If you are connected to the Duet, via Pronterface or the Serial Monitor, and physically disconnect the Duet (without disconnecting in Pronterface/Serial Monitor), then plug it back in, Pronterface/Serial Monitor still has the port open. So the Duet is assigned a new COM port. The Serial Monitor forces you to choose each time, but Pronterface has a default, so if you disconnect/reconnect in Pronterface, it won't have changed to the new port that has been assigned. Though it generally chooses the correct port if you quit and reopen.

I hope that makes sense.
