Connection issue on long prints.

tracar · 15 Jan 2021, 03:37

its been said here lots, and i dont see the fix. after many hours the webpage drops the connection and hangs, both firefox and chrome. ( in my PC) , now im using the latest firmwares. duet2 wireless.
i have had the same problem before with lower revisions.
i can connect with any of my other devices without issue , just not the PC , unless i restart it.
anyone had this problem, and solved it?

Can you provide the results of M122?

im starting another 30 hour print i will repost another M122 after its doneto compare.

tracar · 16 Jan 2021, 03:53

i typed m112 instead, Twice,, noob..... anyways look at the temp during the seconds i did not hit the reconect button........... Hmmmmmm

So you mean you can connect to the Duet with another device like your phone, but not with your PC until you restart the PC or the Duet?

Please post your config.g

yes you are correct, the pc will not connect without a restart.

but tablet and cell will , in both local wifi and or cellular only..

I don't think this is a Duet problem. It sounds like a problem with your PC/browser.

tracar · 16 Jan 2021, 17:59

kinda what i was thinking, after everything else can just not the pc...

did you notice the heaters did that little thing off the scale ?

Phaedrux · 16 Jan 2021, 18:05

The heater graph is pretty weird. It could be interference on your thermistor wiring, or a bad connection. Double check your wiring.

For the browser, when it's not able to disconnect can you open up the browser dev console? Assuming it's chrome?

that is the only time the heater did that,, directly after m112, while it was sitting there with the trying to reconnect popup. and as you can see i entered m112 twice,,, just as the heat graph shows, then the time where it dropped off in temp as i hit the reconnect button,,,

Phaedrux · 16 Jan 2021, 18:18

Could just be a display issue then, if it's never happened outside of that.

tracar · 16 Jan 2021, 18:20

@Phaedrux i will try to recreate the situation after the print is done, , if it spikes i can verify with a thermal probe too.... post my findings later
