Same problem here. Here are the problems I have found:

1. With longer print jobs, the printer initializes in the middle of the print.
2. Cleaning the nozzles, and accidentally nicking and shorting two exposed leads from, heater filament #1, causes the same problem with an itty bitty spark, that could be confused with the reflection from the inside lighting off the wire brush.
3. Extruder #1, with Heater #1, works OK for a little while....
4. Printer operates the same, whether it's plugged into the wall or into an UPS. Yes, I went and bought one for her, in my troubleshooting. Maybe it was a waste, but she'll be happier in the long run, with a nice pretty "digitally remastered" 120 Vrms 60Hz Sine wave.

Here is my working temporary setup, until I can get XYZ to send me a new heating element.

1. Extruder #2 (the extruder containing a prettier element backside) is set to primary (main material)
2. Extruder #1 (the extruder containing the problem) is set to secondary (support material)
3. Support Material set to Medium

Interestingly, electric/resistive heating elements are, in my mind the most common cause of failure in Ovens and furnaces.
In incandescent light bulbs, its always the element that is the problem. So why aren't there extra elements sent with such a device? At a minimum, just one?.?.?.?

I solved part of my issue with the printer failing to initialize. If my computer is off and the usb is connected, the printer won't initialize, but if I unplug the usb or start the computer first, it will initialize like it suppose to. I think some of the shutdown issues while printing stem from the model file. I have one model from thingyverse that causes it to reboot just as the file is finished being received by the printer. Other part files of the same model causes this so I'm assuming it's a software issue. Other than that, my printer is working great. I'm finding out that we newbies need to learn more about modeling software than I originally thought. XYZ needs to print an extensive FAQ in their support page. Right now they automatically want to open a support ticket if you ask them a question...

The first thing I did was verify the outlet. I also put it on a UPS and it still restarted.

Probably the plastic case is building up electro static while the printer is running.

I have had mine for nearly 4 months know. I have carpet throughout my apartment and have yet to have an issue of any kind with the machine resetting rather it is static or not. Sounds like maybe you should check the outlet you are using and confirm it is actually grounded. Sometimes to cut corners or just through forgetting some outlets don't get grounded. Or if someone replaced it at some point they may not have grounded it. The USB ports shield at least on mine is in contact with the metal frame which is in contact with the power supply which is tied to earth ground through the power cable. So if you measured from the shell to the end of the cable that goes to the wall and you have continuity then the break is in your house wiring or the outlet. Static should never affect one of these printers.

I also saw this a couple times when I left the USB cable plugged into printer. Only other time has been while using the metal brush to clean the hotend and accidentally making contact.

I've since switched to using Octopi as a print server. Works wonderfully, I suggest you give it a try if you have a spare computer or minicomputer.

Thanks fawefawef, I actually remove the USB cord from both the laptop and the printer. And since then have not had a problem, so long as I keep the print bed level. The reboot seemed to happen when printing big parts and small ones went smoothly.
Hopefully the procedure described has worked. We shall see.....

Got my DaVinci 1.0 on 12/29/2014 and printed for about 17 hours successfully, yesterday while half-way though printing a sleeve for my pi, it shut down and failed to reboot until multiple tries. I was able to print another project with it just fine, but when I tried sending the next project to the printer it would reboot, I tried a different project from the same model and it also rebooted. tried another previously printed job and it worked fine. My conclusion thinks it's a software issue, but that doesn't explain why it doesn't always boot from a cold start... I've also noticed XYZ has changed the boards from the previous models and are using micro sd cards located near the middle of the board, and the firmware reset pins are gone.

No idea, but mine stopped doing that when I started unplugging the cord from the printer itself, not the computer. Mine hasn't done that since the 23rd, which is a record. When I left the cord plugged into the printer, but not the computer it still restarted occasionally. I thought the end of the usb cable might have been susceptible to a static discharge from the high gloss surface it was resting on, so I started removing it from the printer. I was getting a lot of shocks from the desk while working which led me to that theory. The only other thing I did was turned off windows security essentials active scan while XYZ ware was generating the temporary file to send to the printer. That probably didn't resolve anything but it was something to try and I was desperate. I turn active scan off, hit print, then turn it on after the file is generated and transferred to the printer. I then turn active scan back on and unplug the USB cabe from the printer. No restarts in over a week.

I got my da Vinci 1.0 at Xmas and have had one successful print with it; one of the samples (very nice).
When I tried to print something more complex it just stopped printing part way. After finding this forum I have been recalibrating successfully (thanks) between prints. I thought I had it sussed and went to bed with it happily printing away.
But, this morning I find the part about 25% printed, the print-head at home base and the printer re-initializing every 30 seconds or so. On and off.
It stopped when I switched the machine off and on and now, after recalibrating, I am trying again. With the laptop unplugged.
Any suggestions or theories about what's going wrong will be appreciated but please note; I'm a total noob when it comes to 3D printing, probably wouldn't have one yet if Da Vinci wasn't so affordable, so any suggestions that involve tearing the thing apart are not going to be especially useful. And it has a years warranty so I'll leave the open heart surgery to the experts. After they get back from holiday.
I am posting here because my problem sounds very similar to the original post.
I am running standard XYZ firmware and software.
Thanks, this forum seems like a gold-mine

Update, about 12 hours later.
This time it printed all the way through..!? Great result.
But why? Same file. Was it disconnecting the laptop that made the difference? That's pretty much all I did. I think this result eliminates a hardware fault like a short or bad print head connection.
Theories anyone?

If the XYZware is blocked at the firewall level it will cause it to time out while trying to do its nefarious checking for reset carts and getting the screw up instructions from XYZ.

I have seen this with XYZ 1.33 blocked at the firewall level.

Several other have reported this as well so it sounds like the newer setup..

After cleaning and insulating the heater wires, the issue still continued. I started unplugging the USB cable from the printer itself after the print started and the issue has not returned. I tend to unplug the cable from my computer once I start a print so one end of the cable was resting on a glossy table surface, with the other end plugged into the printer. I maybe in a high static environment or something, it is winter and the air in my house is very dry. That's the theory I'm going with right now.

I was able to reproduce a restart by doing what you suggested. Seems the insulation on the heater wires is loose as the wires enter the extruder tip. I tested during a cartridge load test and if I pull the wires in various directions they will contact the extruder and the printer reboots. I will try to get a drop of plastidip on them which is about the only way I can think to fix the insulation. During the print they must be moving just enough to cause this issue, seemingly randomly.
