Shooting Star BT-3 3-axis digital position readout functions include: Inch/mm display, reversible count direction (change the direction in which the count goes up), automatic centering (find the center of a workpiece or hole by touching off two sides), two sets of coordinates (good for placing hole patterns, making slots and such), enter coordinates (you can enter the values for the current location), bolt circle and bolt line calculators (quickly create a pattern of holes), tool offsets (remember the setting for various lathe tools), and preset positions (quickly return to positions you have saved).

This DRO uses a precision rack and anti-backlash pinion, with an optical encoder on the pinion.

Power: 120VAC.

This DRO includes one 48" scale and two 16" scales. The scales are easily shortened to suit your machine. It will fit on the mini mill with a power feed installed.

This DRO package is specially configured for the X3 and Super X3 mills. It fits the Grizzly G0463 and G0619, and the Harbor Freight 93882. We include drawings of the mounting brackets and notes on installation

*NOTE* These items ship directly from the supplier in Canada. Shooting Start takes two or three weeks to process and ship orders, so there will be a delay before you receive this order.

Chris' Tips
We include installation tips and drawings for installing this DRO on the SIEG X3 and Super X3 mills. These mills are sold as the Grizzly G0463 and G0619, and the Harbor Freight 93885.

See the digital position readout (DRO) comparison.

Scale-Based DRO Packages are designed to mount on any machine within the range of the scales. They all come with 'universal' mounting brackets. These mounting brackets are probably all you need to mount the DRO on large machines. On smaller machines (including mini lathes and mini mills) you will probably need to make some mounting brackets. Note that the Bluetooth DRO packages, except the universal models, come with all the brackets required for the machines they support. All scale-based DRO installations require drilling and tapping a number of holes in the machine.

The biggest challenge is usually the cross slide on small lathes and the X-axis on small mills. On small lathes, the answer is sometimes to mount the DRO scale hanging in space behind the cross slide. On small mills, the smaller cross section of the Shooting Star and the DRO Pros magnetic scales can make it significantly easier to mount the X-axis scale behind the table without restricting the table travel. Glass scales are a challenge to mount on small machines.
