Topic: Print Accuracy / Tolerance

I got my SD3 a few weeks ago, and have spent countless hours on calibrating it.  It's still not capable of making anything close to a perfect cube or circle.  For example, on a 25mm cube, I'm finding that sides will deviate by about +/- 0.7 mm.

What kind of accuracy are you guys getting?  What kind of tolerances can you hold to?

Re: Print Accuracy / Tolerance

So here are my latest prints. Still not perfectly circular but layers and infill are pretty nice. My shapes are usually 1mm off and doesn't really change if the print is larger or smaller. If I make an object 25mm it will make it 26. If I make it 100 it will make it 101, which leads me more inclined to believe that its something mechanical rather than it's the steps...Or a combo. If it were the steps and the machine were mechanically calibrated, I would think the inaccuracy would scale up as I scale up the objects (just a theory though.) It's kinda hard to see the detail because they are clear ABS and the iphone isn't made to do micro shots... oddly enough my 10 dollar crappy web cam can, but it's low res.
