Chris' Tips
You have to tell us which scales you need. This is always based on your machine’s travel.
Here is how to measure your machine’s travel: With the machine off, position the machine to one end of its travel. With a grease pencil, make a mark across where the moving and stationary surfaces meet. The line should be half on the moving part and half on the stationary part. Next, move your machine to the opposite end of its travel, and then simply measure the distance between the marks.
Now, add ¾" to the distance you measured and convert it to mm by multiplying by 25.4. (Or, measure the distance in mm, and add 20 mm.) Round up to the next even 50 mm and that’s the scale you need.
Let’s look at an example:
Now repeat this procedure for the other axes on your machine.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.
