I have an order for my client to print 8 models, I've already printed one of these models for the same guy and it took 18 hours to print Should I even attempt to print 8 models in a row, would this printer hold up going for 120+ hours? Or should I just out source at this point.

I have nearly 700hrs on my Davinci, still going strong, printing as we speak. 

The only issues I have had:
- broken connector to hot end (5 mins to solder xt60)
- 1 clogged nozzle (removed, used torch etc)
- some issues with my poor filament holder solution. That's on me
- xyzware crash glitch which does not affect printing

So really... only a broken connector.

Itll last 120 hrs no problem.

I've also took apart my extruder to clean, acetone bath, torching etc. As it turns out it wasn't the extruder that was the issue, it was the filament that the printer came with lol

I did mean in one print, well a series of 8 prints in a row totaling about 100 hours. So far I am on print number 2, all good.

Itll last 120 hrs no problem.

He means in one print. lol I mean im touching 2k hours on my first davinci and it still runs like a champ lol.

I have a camera on mine and it's plugged into a Edimax IP switch that allows me to turn the printer off remotely.

I've never used this for fire prevention, but have used it multiple times to shut the printer down when it's become obvious that it's a failed print.

While I can agree that my solution isn't as good as actually being there, it is good enough to suit me safety wise. After all even if I ran it only when I was physically there, I am never constantly watching the thing. I go do other things after the first layer is done and let the camera watch the machine. I tend to drag some kind of "monitor" (phone, tablet, or computer screen) where ever I am and look over at it every so often.

could you elaborate, I am really considering getting some sort of remote shut off app. I am away from the printer for the most part and would love the ability to shut it down after its done printing or failed to print. Nothing worse than coming home to a web of birds nest.

Its been over 10 hours now, everything is printing fine. I do however notice a strange screeching sound that comes and goes on certain layers. Maybe its the filament running low, anyone else notice any scrapping/screeching noise when printing?

It still could be just careful over hype for the sake of safety. This is just one person that has reported a fire out of how many millions of printers used daily? I know the risk is there but it is also minimal with some easy protection measures. Electrical fires are on parts designed to self extinguish
once power is removed.  So remote monitoring with ability to kill power is best option. Then a steel enclosure is an option.  There are other measures but again this is a rarely seen or reported issue from millions out there.

Not trying to pass it off, just curious if the risk is that real. Been printing myself 8 years and leave the house with printer running daily. Still lucky I guess.

I hear what your saying and have in the past left my printer running unattended.
Then not long ago things froze with heaters full on for no explainable reason.  No big deal since I was right there but it sure makes you rethink the issue.  I would like to think I keep some of the best running and well maintained printers around.  Just imagine all the hacked up wiring jobs out there.  You'll notice I stayed out of the whole "beware" thread, I'm sure because I feel a lot like you about the issue.  That being said I think it is very important that the overall message be not to leave your printer unattended.

Long story short don't worry about it. lol

I printed a 26 hour print on my 1.0 with a stock head. I had no issues. I do use rep firmware and host however. But it still did 26 hours. The issue is can you watch it all that time or do you have a steel box it can be placed in. There is a fire hazard with any 3D printer and long prints like that tend to have people start and leave which is a bad practice I myself am guilty of sometimes.

I was planing to set up a web cam, I do tend to start a print and leave

I guess a webcam would do no good unless I rig some sort of extinguisher and a smoke detector right above it lol

The smoke detector is a good idea. but as others have said. If you have smoke, then you usually have fire and it is too late for the detector then. The best course is to stay with it, or put in a location that if it does catch fire it won't spread to anything. Or inside a steel box so it will be contained. I now one guy who keeps his in his fire place that he never uses. That way if it catches fire, it can just burn up in there and not do any real harm other than smoke and toxic fumes which you you can wait out somewhere.

Then again you could be stupid like me and take your chances. I have left for work and left a print running many times in the last 8 years. Guess I am just lucky nothing has happened.

Unless the fire hazard is over hyped just for safety.

I was just gonna ask, has anyone on here had a fire yet? I can see how this sort of thing can be hyped just for safety purposes. What would actually catch fire? I can imagine a short may cause a spark other than that I can't imagine that thing catching fire from the extruder.
