Essential addition to a Mini Mill
LSM✓ Verified Purchase•December 30, 2023
The ToAuto DRO has been an essential addition to my Little Machine Shop 3990 Mini Mill. I purchased the 150mm (y-axis), 300mm (z-axis), and 350mm (x-axis) glass scales. With carefully thought out installation, this DRO has performed flawlessly! It makes machining on the mini mill very easy because there is no need to lay out feature dimensions on a workpiece. Using a simple edge finder, spot drill, and the DRO; positions for drilled and bored holes are extremely easy. Milled features are simple to accomplish as well. I used the DRO to machine several parts for a power feed on the x-axis. This project required the precise machining of three mounting plates so that there is exact alignment of the components when assembled to the mill table. The ToAuto DRO made the process easy and accurate. Also, the custom ordering process went smoothly and customer service was terrific. I highly recommend ToAuto DROs.
Can't beat it for the price!

Surprised at how fast this arrived. Ordered Monday received Saturday with xmas in between. Box arrived ok but hardware bags had split and screws were rattling around in the box. But overall I think packed quite well. No mounting instructions but not too hard to figure out. A dimensional drawing of scales would be nice. Mounted on a Bridgeport so brackets included were of no use to me. You will have to build a bracket or two for y and z just like on an exspensive setup. Fairly nice lightweight covers for the scales made of aluminum extrusion. WIll keep chips out but will get dinged if something hits them. Resolution can be set to either .0002 or 5 decimal places. Mounting arm for the DRO could be a bit longer. If you tighten the DRO brackets pretty good seems ok. So far I like the DRO features. Just like lots of imported stuff the grammer, syntax, and naming conventions in the DRO manual need work but not undechiperable. Unless you must have a name brand I can't see much wrong with the setup.
Very good DRO

I bought the 3 axis package for my Bridgeport. Mary and I had a brief discussion about the length of the encoders and the DRO arrived in about a week. It was exactly what we had agreed upon. The encoders had glass scales and were easy to install, the gaps and parallelism of the mount were very forgiving making it easy to get up and running.
The readout has many features making things like bolt circles and hole patterns easy to program. The readouts are bright green and their intensity can be set from dim to very bright over 7 levels.
I am planning to buy the 2 axis version to replace the Heidenhien DRO I currently have on my lathe and if you are in the market for a DRO, I would recommend this product as it is a good value for the money.

As a hobby machinest i don't have deep pockets to buy other brands of DRO's. This product more than met my needs. It's only weakness is installation instructions. Scales require an accurate precise installation. Review of installs on youtube and product video were enough to install but should have Had tolerance info.
Good for my hobby mill

After using this DRO set for 6 weeks, the only fault I have is the manual. It is written in Chinglish. I had to combine bits from other online manuals to understand some of the DRO functions. There are no instructions for installing the scales, because every installation is unique. There are many included fasteners of different sizes. You won't use them all. I did not use the included mounting brackets. Made my own. The extra long 9 foot cables allow you to place them wherever you want. The selection of 3-scale sets offered on this listing are pre-packaged in China, if you need other sizes look at other listing. Longer scale are OK if there is room to mount them. Two of my scales are longer than needed. One scale I cut shorter. Yes you can shorten glass scales, but think it through before attempting. After carefully removing the very delicate thin glass, it scored with a simple glass cutter, then snapped easily. I'm happy with this purchase.
