Thank you for taking the time to do some 'splainin for me! This really helps. I am planning on ordering up a 2 axis pretty soon (by pretty soon I mean as soon as my wife forgets how much I just spent on other stuff). Again, thanks for the help!Hi Ironken,
Sorry the delay; Saturday is my day at the workshop.
The DRO is OK for me.
I never had or used a glass scale DRO before; my experience was with iGaging and Rotary Encoders, custom made electronics/software.
The one I got from eBay is much better, mainly because of the glass scale technology.
As Wawoodman said, just install the scales firmly, keep then parallel to the machine axis (horizontal and vertical) and it will be fine.
The manual is not totally useless. It is extensive (54 pages) with good drawings and good paper; only the text is hard to understand. I assume it was translated to English by someone not really fluent. With some head scratch and deductions I was able to do everything I needed, like reversing the direction of the measurement (+-). After figuring out there is a hidden button on the bottom left corner, for configurations.

Gonna pull the trigger tomorrow on one. How long did shipping take?Hi Tweinke, thank you.
The DRO are from eBay, seller 88490755.
Like this one: http://www.ebay.com/itm/NEW-DRO-3-Axis-digital-readout-with-high-precision-linear-scale-linear-encoder-/162359087225?hash=item25cd5b1079:g:wuIAAOSw4GVYUPuF
Fast free DHL shipping from Honk Kong.
Works as described. (except the manual, that is useless)
I would have made you proud cause drillin' and tappin' I did.....and plenty of it. I posted these pics up elsewhere on this site and figured I would put them here as well. Install was pretty simple, just a little tedious.Installation is going to be a little different on every machine, with every different supplier of the DRO. Go slow, think it out, keep it all square and parallel. Don't be afraid to drill and tap holes in your machine, or make new brackets if you need them.
You'll be fine!
I am out of town now and cannot measure. I do know that my table was quite a bit larger than my travel so, I purchased scales that were near the same size as my table. This gave me enough room for my reader head to work through the full travel of both axes. These kits are not a bolt on deal. They require some fab and ingenuity but, I absolutely love having a DRO. Check out DRO PROS. They have detailed videos on youtube on measurement for glass scales.what size scales did you buy with the kit?
