Hi,

i saw on internet that mach3 have function to program it manually. It is programmed like that: you pick coordinates  on your cnc machine working table ( manually, jog) and fix it each by pressing button. After that you press start button and machine repeats all coordinates.
Maybe somebody know or have any ideas how to make it?

CopyCat in the Mach3 Wizards will do just that although you need the Wizard License for it to run full function.

There is also JCode which can be downloaded from this page; https://www.machsupport.com/downloads-updates/mach3-downloads/

Tweakie.
