Anybody had trouble with temperatures dropping mid-print?

I’ve been printing a job almost 24 hours a day for past week or two, and 3 times now I’ve had a print fail half-way through. Same GCode, no changes. The part will look normal up until where it stops, and after the fact there’s no evidence of what really went wrong… This time I logged in to check on a part, and caught it in the act. The machine is still running, but the temps are both set to 5 degrees so it stopped extruding (by the look of the ZHeight) a few hours ago.

What are the pitfalls of AstroPrint to avoid? Could being logged into the UI on multiple devices cause this sort of a hiccup? Often times I’ll start the job on my computer, and then I’ll check on it from my mobile. Can those two connections step on each-others’ shoelaces?

What about printing from SD? The printer show up as “ready” instead of “printing”, and it makes me wonder if connecting to look at the camera is interrupting the job and making it lose it’s temp setting.

I think I’ll unplug the printer and just use Astro as a web-cam for the next print or two, just to see if it helps. Any advice?

The temp controls in mobile are very small and sensitive. It’s possible that you inadvertly set the temp to 0 ( which some printer set target to 5 ) while monitoring the print.

That’s good advice, I’ll be especially cautious about that from now on.

Could future versions add a way to lock this out, or to ask you if you’re sure when a temperature change is detected?

I’m having the same problem and I’m been very carefully not to login from and I can not find out why after a while the temperature on the nozzle drops I keep a good look and it print s fine beautifully and after a while it drops and it does not work,again how,can I fix it
