Need better recovery from interrupted upload



  • I have an 8MB file which only makes it about 30% of the way before the Wifi connection fails. I think two things should be added:

    1. watchdog on the wifi connection (reset if a ping to a programmable IP fails)
    2. allow recovery from partially transferred files so I can eventually get the whole file. Ideally without me having to resubmit but most important is to have the ability to transfer the file.

    Right now my work-around is to carry the printer to the same room as the router (-46dBm) to make the transfer then carry it back to the print room (-61dBm signal strength) to make the print (eventually, I will add the extra sdcard slot which will be easier, but for now it's heavy lifting for me).



  • That's too bad about your network setup. Could you potentially add an access point in the same room as the printer? Say a powerline ethernet access point if you don't have cat5 already in the room.

    Or a cheap wifi repeater such as the TPLink WR810N ?

    I'll give some thought to pinging the gateway in a future firmware version.



  • I do have several cat5 ethernet ports available in the room - wishing I had gone with the Ethernet version now but thought eliminating cables would be good. I will try the repeater. You are right, for $40 it's hard to lose. If it solves the problem then win. If not, well I now have a travel router.



  • I bought a mini router and stuck it in the middle of the printers. Solid connection almost all the time, chose a new ssid just for the printers, so no other devices are using it, and a channel which is clear. Cost £15. But I agree, if ethernet had been available at the time I would have gone with ethernet.



  • I love the Duet Wifi but kind of wish it had an ethernet port instead. Wireless is great for mobile devices. Not so much for stationary equipment like a printer.

    That's why we make the Duet Ethernet too!



  • So there is an external antenna option available for those comfortable with surface mount rework. Can the same be said for replacing wifi with ethernet. Looks like it is sitting in a socket on the same pins as the wifi.



  • Looks like the answer is yes.

    But where to buy the ethernet daughterboard?



  • Since you must power off the printer to work your existing bypass… just take the one and only SD card to your PC.

  • Well, no luck with the repeater yet. I didn't do a whole lot of debug - just went through the quick start routine. It actually made things worse. The Duet couldn't connect at all if the WR810N was nearby. I can try setting it up as a router instead since I have ports available but at this point I think I will try the board swap.


 

Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
