Re: what would cause this problem?

I'm not sure if I would consider any of that 'flawless', but the model could have a hole in it (Run it through netfabb before printing)

sorry i meant the front is flawless compared to the back. also i already ran the model thru netfabb, which didnt indicate any problem with the model.

Looks to me like you need to adjust retraction a bit on layer change. And, if not already set, randomize your layer starting points.

Re: what would cause this problem?

What layer height did you print that at? There is a lot of banding in it that should not be there. Also what temp was this printed at and what speed? It looks to me your temp was too low and the speed was fast in some areas. The hole looks like a place that was too hot too long and did not get enough filament due to poor flow caused by the hotend not being hot enough. The filament has a flat look when it should be glossy or semi glossy.

Printing since 2009 and still love it!

Re: what would cause this problem?

On a Da Vinci i would not go below.15 on layer height. I have yet to see a stock Da Vinci do a good print at .1, I honestly don't think they can actually do it even though XYZ claims they can. I know mine never could till I replaced the controller.
