Regardless, a bad Ethernet connection should not cause any juddering or printing issues as it is used only for control during printing, not print data transfer.

I was asking because this software especially atvise is not very common and I am wondering if there is maybe a better software that is easier to handle and we are looking also for a better licensing model but we could not find anything suitable yet.Quote

Hi Bart,
I suggest you upgrade to either dc42's firmware or to my latest one. Don't forget to add the M574 code as seen here to your config.g file.
The reason you're experiencing this problem is an invalid JSON response sent from the firmware and I remember having fixed a related bug a while ago. If an upgrade doesn't fix your symptoms, this would mean you're having a really unreliable network connection and I'd advise you to try a reset of your TCP/IP stack first. See [support.microsoft.com]

One thing I have noticed with the Duet is it can be sensitive to other network traffic, I found that when I turned my TV on then my Printer would start shuddering and the connection would become unreliable, the eventual cause, was identified as my HDMI-LAN converters that allowed me to distribute SAT TV to other rooms in my house.
This problem was fixed in one of the newer firmware updates by changing the priority of the web server (or something like that), but I still notice disconnects when I put my printer on the domestic network, but when I put it on a Printer only network or direct connect to my laptop which doesn't have any other traffic then it works very reliably.
The thing to remember about the duet is it only has the one processor, and when you consider that its doing G-code interpretation, Driver management, running a web server and FTP server.... its getting pretty busy, and sometimes it drops the occasional ball, as long as the ball its dropping is only the web server then that's not too bad, its when your printing quality suffers you will have problems.

A wired Ethernet LAN should not suffer too much from high network traffic between nodes that do not include the printer and web client. Congestion occurs when the traffic is passing through a common node - e.g. the Internet gateway, the "backbone" connection between two different hubs (switches) or WiFi connections via the same hotspot.
Regardless, a bad Ethernet connection should not cause any juddering or printing issues as it is used only for control during printing, not print data transfer.

Hi bgdavis,
I'm ok with the Duet dropping the occasional ball, but when it starts dropping anything and everything that's not cuboid, it gets annoying!
I don't have much traffic on my home network (none that should be there or that I know of anyway) and I haven't had a disconnect in months. Until now.
What do you mean by saying that you direct connect to your laptop? Is there a way to plug a network cable straight into printer and PC with no switch inbetween?
Cheers,
Bart

Yes, I only suggest it as a diagnostic check, sometimes isolating everything helps.
First you need to reconfigure your config.g to fixed ip and give it an address like 192.168.1.14, then you need to do the same for they pcs network port just use a differnet ip address isq192.168.1.100, then you just run a regular network cable between the printer and your computers com port. And try and access the printer using the 192.168.1.14 address

Hi FatFreddie,
Ok, so I would need to change the firmware to dc42. I may do that, but that still doesn't explain why my home printer/computer were fine for several months and have now suddenly started having issues with disconnections. The work printer is also controlled from a Vista computer so maybe some Windows update messed things up.
Cheers,
Bart

For diagnoses, just unplug the wall connection just after you have connected to the printer and see whether the issue goes away. Also make very certain that you do not have an IP address conflict (the Duet using the same IP address as something else on your network). Maybe change the Duet IP address and see if it makes a difference.Quote

As I said in my original post, the work printer and control PC are connected, both by cable, to a network switch, which itself is connected to a wall network socket. I have no control over what happens past the switch. In my limited knowledge of networking, I thought of replacing the switch with a router with DHCP/local IP adress allocation capabilities but I don't think work take kindly to us plugging our own routers into their network. I suppose I could always leave that router unplugged from the network (and use it as a printer and control PC-only local network) and plonk another network card into the PC and use that to connect to the university network. Would this idea work in terms of having a guaranteed congestion-free path from PC to printer?

As concerns my home printer (which, after many months of not a single disconnection, has now suddenly developed the same connection issues as the work one: both control PCs are Vista so I'm thinking maybe a recent Windows update messed things up?), it connects (by cable) to a network switch which itself is connected to my DSL router (the network switch is there because another computer is connected to it as well, but that computer is very rarely on and hasn't been on since the disconnection problems developed). The printer control PC connects to the DSL router via WiFi. The question remains: why has the setup worked flawlessly for several months and has only now started failing?

It could be that a recent Windows update resulted in your PC's protocol stack changing in some way that triggered the symptom. There are many variables in the TCP/IP stack - window size, MCU size, timings and timeouts etc. Also PCs can sometimes generate the broadcast storms I have mentioned.Quote

Installing dc42's firmware (1.09k) on the other hand seems to have done the trick: not a single disconnection during a 5 hour print. I'll restore the setup to what it was before (with network switch etc) and hopefully it will still work, but so far it's looking good. This still does not answer the question why I had not a single problem for nearly 5 months and then the disconnections suddenly started, but don't look a gift horse in the mouth I guess eh.Bart
