Re: How to cut out pcb

As Jeff Birt says in Mach3 you can write an M6 macro to so whatever you want.  In the past I had a macro that would stop the spindle then move to a “tool change” location.  Now with a tool changer my macro has “evolved” into a “tool change/tool measure/resume” milling macro.  As I don’t use (or like) tool length tables I like my “tool measure” macro.  Very cool.




Thank you,

Whether you have an automatic tool changer or not you have to have an M6 in there so your machine controller knows a tool change will happen. What your machines controller does with an M6 is up to the controller. For example on Mach 3 you can tell it to ignore tool changes, you can stick with the stock M6 macros that just stop the spindle and wait for you to press START, or you can write you own custom M6 macros to do whatever you want.

Wow. Thanks alot !!! It works perfectly :)

Something else I noticed (not on topic) is that the gcode created for drilling asumes the cnc has auto-tool-change and writes M06. Shouldn't there be a checkbox for that ?
