This magnetic technology digital readout package fits virtually any milling machine with less than 31.8" total X-, Y-, and Z-axis travel.

This kit includes 1 meter (39.4") of magnetic scale that you cut to the lengths required for your machine. The instructions tell you how to measure and cut the magnetic scale.

This package includes what you need to put a DRO on most any milling (or 3-in-one) machine. It includes a section of scale, three read heads, and a Bluetooth transceiver. Typical mounting bracket designs are included in the instructions. However, due to the wide range of possible applications, appropriate brackets cannot be supplied.

You must also get an Android tablet for the display on this DRO. We recommend a 7" screen size, and the tablet must have Bluetooth capability.

Chris Chris' Tips
Here are installation instructions for the Universal Bluetooth DRO.

While we sell an Android Tablet with the DRO software installed, you can use most any Android tablet that supports Bluetooth with the Bluetooth DROs that we sell. 

Here's how to get going:

  1. On your Android tablet, go to Bluetooth Settings and Pair the DRO to your tablet. The name of the DRO is HC-06 or BT04-E. The PIN is 1234.
  2. Go to the Google Play Store and install Yuriy's Toys TouchDRO.
  3. When you launch TouchDRO and tap Connect in the upper right corner.  
What's it take to assemble a DRO?
