One of my favorite tool additions!!
Greg✓ Verified Purchase•November 11, 2023
Love this DRO! It brought my Grizzly G0484 mill into a whole new level of accuracy and repeatability. It took me a while to configure and properly align the attachment brackets but that's just part of the fun. Plenty of videos out there to help guide you along the way.
As to ToAuto...I can't say enough good things about this company. I ordered this DRO just before the world turned upside down. Because of that, it was delayed getting to me. Their rep Daisy reassured me it would arrive...and it did. Still, it the midst of everything that was going wrong, their openness and constant contact spoke volumes for this company.
In hindsight, I'd say to be ready for a bit of a delay for it to arrive but be patient...it's worth it.
Lastly, the pro machinist that was teaching me said this DRO was as good as his that cost him many, many times more.

Essential addition to a Mini Mill

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.
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.

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.
