The issue that generates an 0014 is an issue with the thermistor. Either the wires on it shorting together at some point caused by hotend movement or they are shorting against the heat-block at some point again caused by movement. Or there is an intermittent open connection between the thermistor and the mainboard. That opens when the hotend is in certain areas of the bed long enough that the system sees the temp outside of range for too long.

All I know is my machine goes BEEEEEEEP BEEEEEEEEEEEP.... repeatedly, with a red led, and the extruder will not heat over 34 degrees C.

I have no idea what to do or what to look at. I also can't download new software or update my firmware as there's an 'unknown network error' although every other program woks fine. Any advice or troubleshooting tips would be fantastic.

I got an unused DaVinci 1.0 at a local estate sale a few weeks ago. The notorious bearing holder brackets broke on the second week, and the extruder stopped heating on the third week.

Got new brackets printed (thanks to super gluing the old ones) last week, and just now replaced the stock heater wire connector with a deans connector, as recommended in this post. Looks to be working just fine again.

From the sound of it, I'll be on this forum looking for another solution before too long.

I have to say, it's still been worth it. This is my first 3D printer, and considering the price I got it for, it's been a great learning experience for me. I've gotten more into the guts of this thing already than I have with most of my gadgets, being more of a hobbyist than a real tinkerer. (I confess, this is the first real solder job I've ever done.)

You folks have been invaluable. At last as far as keeping me from tossing this thing off the roof.

No,  enough excuses.     DaVinci machines are pure unadultrated crap through and through.   Most import Asian discount machines are --- you get what you pay for.    It held true in the factories I worked at and apparently a $500 printer is too good to be true as well.

Bad enough they want us to buy their material and go to great pains to make us do so...   and now this.   

Yeah,  done with DaVinci.    JR is going out the door next.

The hot end is the issue. The board is the result.

and what is the solution? can this part be replaced/fixed?

Not a big reader of prior post are we? The solution was stated about three post before the last.

I asked this quetion for diagnostics. If you clean the nozzle while powered with the brass brush you cause a short that blows the zero ohm protection resistors at the heater output on the mainboard. It is a common mistake and common issue with these printers due to their hotend design.

Oh.. I see.. yes. that could definitely be a reason for this.

Is this fixable?

So THIS is what killed my mainboard.  GOOD to know.   

I'm not putting this POS back in service,  I'm gutting it for parts.   I am not paying to ship the board back to them to correct an issue that should have never happened in the first place.

If this is a thing, then why the HELL are they selling them like this?

It's not dead, it is repairable as many here have done so.

The problem is that the heater cartridge has exposed wires at it's body that the insulation does not cover. The brass brush being a solid short runs across these wires and if this happens while power is applied to the heater it blows the zero ohm resistors near the heater output on the board. They use these zero ohm resistors as fuses. Unfortunately unlike fuses they are not in any way, shape, or form easy to replace for the average hobbyist.

Depends on your soldering skills with surface mound components. The bad resistors need to be removed and then new ones which can be ordered from mouser or digikey put back in . But it does require surface mount soldering and desoldering skill.
