DRO 2 Axis Digital Readout Display with 2pc Glass Linear Scale 5 Micron Accuracy for CNC Mill Lathe Machine (300+1000)

I ordered this DRO after watching many YouTube videos of folks that have bought the same or similar. It works exactly as it says it will, as backed up by indicators and micrometers in my shop. There is a process to dial in error. In my case, there wasn't any worth messing with. If you want it balls on to the tenth ... you can make those calibration adjustments.For the new machine hobbyist like me - beware, this is not for the faint of heart. It is not hard, but very meticulous and time consuming using tools far less accurate that what you've become accustomed to (In many cases I hand drilled holes in the lathe body). From the videos I watched, I fully expected this level of effort. I had to fabricate some brackets, drill and tap many holes on my lathe, machine some standoffs, etc. If you've had a small lathe or mill for a while, this isn't a big deal. It took me 4 evenings after work to get it done. The good news is that the scales were designed for this expected less than accurate drilling. They are slotted and allow you to adjust finely running an indicator along the scale until it runs parallel.Hope this helps!

DRO and scales work fine.Installation takes a while to do, but worth it in the end.Couple of words on installing it-Model all the parts if you can including the guards-The covers come with endcaps. Model those too because they can interfere with other components-My lathe is cast so there are no flat surfaces. I had to machine some myself. WD40 on it until you paint it later-There is a total of about 2mm of play between the casing of the glass scales and the sensor. Its also spring loaded somewhat. This is good for an assembly. There is also a red 1mm spacer in there. Keep that in until you have everything installed, then pull out the red spacer. The spacer keeps the sensor at a nominal set point of 1mm with a +/- tolerance of 1mm-Move cross slide towards you. Tighten that end of scale with just enough torque to hold it in place. Then move the cross slide away from you and tighten that screw. Move back and forth and assure no binding occurs.-I have a shop light right over my lathe bed. I had the light right at the level of the display and could not read the numbers. I am going to lower the light so it is just below the DRO.More notes to follow

I'm happy with the purchase. I messed up on cross slide scale measurement. It was easy enough to cut to size.No regrets.

The seller cut both units to fit my milling machine X & Y travel after I provided the dimensions - no charge. Everything was packaged very well. I mounted this to my Millright MV1 vertical mill - X and Y axis as that was all I needed for what I do.I had to make custom mounts for the Y-axis, but that is to be expected. There are no installation instructions, but if you are even a weekend machinist, you should certainly be able to figure this out.Indicate the bars relative to the travel, and keep the orange spacers in place until you are done.The unit works perfectly.

Has worked well. Communication with seller was good. Like all import stuff, the instructions are useless, and mounting hardware is just general hardware, and user has to cut/fit/ design, but is to be expected.

I installed this on an inexpensive 9X20 lathe. I was determined to mount it in such a way that the scales did not get in the way, which required mounting the ‘X’ scale on the end of the cross-slide. That made the brackets more complicated and the chip shield had to move. So, installation required a bit of fabrication. Don’t underestimate that part of the project. But if you think it through, you will be pleased with the end result.Customer service was great, taking extra care to make sure the scales were sized properly, and it arrived quickly.I expect that to do business with this seller again.

I was using one of those bargain DRO's it wasn't working for me, so I decided to purchase a better one. I purchased the ToAuto because of the excellent reviews, and also all the helpful tutorials available on YouTube. I want to make sure, the glass scales are the proper size. The representative from the seller, made absolutely sure I was getting the proper length scale. The complete kit arrived two days earlier than expected, wonderful surprise. Now as far as the units concerned, form my pictures you can see it is in-service, and performing excellent, super accurate. Update 2,4,2023, DRO in service for several months, we had a job I wanted to share. This is called a detent plate, used to control production machines, the ToAuto DRO made it easy, and fast.

For the money, this is a great upgrade to my home-shop lathe. The instructions are not clear for the initial device mode setup (mill, lathe) but the seller's video helps. In lathe mode the x-axis can be configured for diameter. You can specify the direction of both scales so there is no concern about mounting orientation. There are no scale installation instructions but honestly, if you can run a mill or lathe you should be able to figure this out. The head unit can perform a lot of different tasks and calcs and it has a large tool library. The head mounting system is sloppy, but a novice machinist should be able to fix it. The kit comes with nice scale shields but they simply didn't work for my installation so I bent aluminum flashing to protect the scales.This kit requires a lot of planning and a little bit of time and effort. The installer will have minor problems to overcome - just like any fun project will. I give it 5 stars because it was exactly what I expected and is accurate.
