Description

1, 2, 3 or 4 axis SimpleDRO™ (digital readout) is specifically designed and manufactured to fulfill the gap of easy to build, install and connect to your favorite machinery. With flexible installation variations, the SimpleDRO can accommodate nearly any set up – from a simple one axis drill press and lathe, to up to 4 axis mill setup.

On the front panel are Half scale (½) (Diameter/Radius), Standard and Metric (in/mm), All Axis Reset buttons allow to use Absolute or Relative coordinate system. Additional options include Rotation Speed (RPM), and Current (Load) sensor reading.

SimpleDRO™ is specifically designed for inexpensive and relatively precise (resolution 1.2um/0.0005”) capacitance scale. Calipers, “Standard” Chinese scales, iGaging DigiMag, and AccuRemote scales fall under the category of “capacities” scales in different forms and sizes, they all offer roughly the same resolution, repeatability and run-out but differ on other important parameters. Please check a great resource of scale selection and others, available from google.

You can use a 21 or 24 bit scales, but our open source software supports almost all common 21bit scales – please check with your supplier prior order.

Software

A few compatible open source options are available for this design:  Check out  Youri’s Toy and Ryszard Malinowski site for more information.  There are dozens of different forks and versions available for 21 and 24 bit scales, glass scales, angle encoders, etc.

Please check other available search options and asses your needs before engage in this project – this project are require certain skill set to make it works.
