Manual Tool Change

[m_c]

M6start and M6end macros control everything IIRC.

You also need to select the correct option in the main setup screen. I seem to remember top left corner, and gives the option to ignore, or pause on M6. I'd confirm that, however I've not got Mach3 installed on anything convenient just now.

There are starting-point macros loaded with Mach3 so you should have them already - names as per m_c's post. You can then tweak these to suit your machine. There will be a set of machine-specific folders in c:/Mach3/macros, and I think that each folder gets pre-populated with the standard set of macros. I use a text editor as I'm not sure that you can really call the scripting language BASIC.
