DAVID TT-1 Automatic Turntable

works as expected, good quality

I received the TT-1 as a gift recently so this won't show up as a verified purchase. But if you go to thingverse and do a search for billyd you can see some of the scanning work I have done with the SLS-2 scanner and the TT-1 turntable.I love this product. It's expensive, but you get what you pay for. First off the construction of the product is amazing. The anodized machined aluminum housing and extremely tight fit and finish is the first thing you'll notice when you take it out of the box. This is a fine piece of German engineering. There is zero slop in the turntable as a result, and rotations are extremely accurate. Super important for accurate scans.As for how it works, it is designed to seamlessly integrate into the DAVID 4 software. Scanning an object without the TT-1 tends to be a bit tedious. The process is scan, rotate by hand, stitch, scan rotate by hand stitch etc. But with the automatic turntable, the object rotates between scans (to any degree you specify) for as many degrees as you want automatically. Also the David software automatically stitches the scans with each rotation. Since the software knows how many degrees each scan is taken relative to one another, the stitching process is generally flawless in comparison to stitching without knowing the new orientation which is hit or miss. You place an object on the TT-1, press the scan button in DAVID and a 360 degree stitched scan is completed hands off. Then if you lay the object on one side and repeat the process, and then place the object on its other side and repeat the process, you will have a perfect scan of the object with every part of it scanned and stitched.In the end it takes a process which used to take me sometimes over an hour to complete, to less than 10 minutes. And the scans are amazingly accurate. I can't recommend the TT-1 enough.ps I recently completed a video of the SLS-2 with the TT-1. Once it is posted online I will edit this review and place a link to it.

After using the David turntable for a month I was disappointed. All it does is spin. There's no logic or special anything about it. Ultimately I returned the unit and purchased a Zcapture Pro turntable. With a little tweaking to make my own app to run on its Arduino I was able to make a system that does exactly what I want at a price that is half of this turntable and can be used for 360 product photography also.
