3 Jaw Chuck offset calculator.
As an apprentice I was shown how to offset the workpiece in a 3 jaw chuck for eccentric turning, the method has served me well for many years. Thanks to Marv Koltz’s equation, here is a small program that calculates the packing required under one jaw.

Measure Tools
I wrote this small program for use with machines that use tool setting probes. Saves time not having to constantly write MDI commands to load and then measure tools. This program can quickly create the GCode do the job automatically.
Also useful for loading tools where the machine does not have a ‘Next Tool’ button.
I usually create one program with the measure macro calls (e.g. G65 M9857) and another without. Pressing cycle start prepares next tool pocket for loading.
Simply click the checkboxes for the required tool and click ‘Create GCode’.
Entering the tool diameter in the adjacent Diameter box will add that tools diameter value to the end of the macro call line.
