If anyone was curious on some of the quality of the Alibaba stuff I bought here is some pictures seems fairly well made haven't checked Run out on anything yet but looks good if that's worth anything lol.
There are many DROs on the market. I have bought mill tables and vises from VEVOR. Good quality.A friend recently informed me we were both buying a Vevor 3 axis DRO for our mills. US$200, free shipping anywhere in the US. We both have X and Y scales installed (Z to come soon) and we are both impressed with the quality/function of the system.
TouchDRO plus a Fire10 tablet came in at about $250. The scales remain the pricey part at about $100 per axis. But for that you get the nice low-profile, easy to trim to length magnetic scales.For many years a DRO that would do this was in the $800-1000 range so I couldn’t afford one but at this price….
The I-Gaging DROs are simply for X & Y location readouts. I have been told by a few members that the Data Ports can be hooked up to a processor/display for geometric shapes, but I haven’t went that far yet.Interesting concept with 2 readouts. Our Vevor DRO’s came with the 3 scales, will do bolt circle calculations, center finding using 2 edges, imperial or metric measurements, absolute/incremental, where to drill holes for a radius, preprogrammed tool diameters, and a built in calculator that does trigonometry. There might be more too! For many years a DRO that would do this was in the $800-1000 range so I couldn’t afford one but at this price….
