To download - Open link and click the download tab at the top of the page and follow instructions.
To use - Input the number of division. Degees are indexed on the table circumference itself and the Minutes are indexed on the handle. It can generate data for divisions up to 6400 steps.
Example: 25 steps is 14.4 degrees in decimal but is useless on a rotary table. After conversion the table increments in steps of 14 DEGs and 24 Minutes which can be set directly onto a rotary table.
