DRO 3 Axis Digital Readout Display +3pc Glass Linear Scale for CNC Mill Lathe Machine (150+200+300)

they fit good on my Wen 33013 mill, just make sure you have plenty of drill bits, you will break a few installing these, the cast iron like to eat bits, once installed which is easy (besides the bits breaking), it works great, very accurate and read instructions, programming will get easier with use, I highly recommend these, make sure after you order to check the messages from the vendor from orders screen, then problem with order, they will ask you for confirmation of the sizes.

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.

System worked very well. Enclosed brackets were not useable due to size, but gave me some spare aluminum angle stock.

So far it works like it should. A little challenge decrypting the instructions. After that with custom made mounts it works great!!

Very nice and easy to read display with protective cover. Now that I have it I can't live without it. It has cut hours off of every project. Very precise and has more capabilities than I expected.

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.

I ordered custom lengths (X/Y/Z=350/200/300) for a Grizzly G0463 mill. Increments of 50 mm only. This is a DIY kit with no instructions whatsoever. To get an electronic copy of the manual for the display, go to their website. Refer to the photos for details on the install. The scales have been accurate and repeatable, with easy on screen switching between metric and SAE. The read heads run underneath the scale, which keeps things cleaner, at least for the X & Y axis'. The included hardware, including scale covers are nice. I was able to use some of the parts, with the rest custom machined and 3D printed parts. I don't like that the read head is the same thickness as the scale, which requires you to shim the scale out to keep it from rubbing on a moving stage...a minor issue.

I installed this product on my Rockwell 21-100 3-axis milling machine. There are no installation instructions included, but "ToAuto" does offer an install video on YouTube. The guy in the install video made this seem like a "slam, bam, thank you mamm" install process. It's not.Had to make most of my own mounting hardware. The only hardware I used from the kit was the metric screws to mount the read heads, and 4 of the 6 "L" brackets, which all required being corrected to a 90° true angle. All the rest of the mounting hardware was of my own design. The "hardware" (flimsy plastic guides) that are intended to hold the read heads centered and in-place while installing the screws to the brackets leave a lot to be desired. They are flimsy and do not hold the read heads solidly while locking the read head to a bracket.The User Guide requires a fair amount of "WTF are they saying!" scrutiny. You can get a LOT more guidance from watching YouTube (recommend "Blondihacks") on how to use the device.This is NOT a rush install! Take your time... I took nearly 30 days for mine, but I'm retired and I have a LOT of time on my hands.At this point, I'm pleased with the performance and accuracy of the device.
