I'm a beginner using Mach3 with LazyCam and I can't work out how to create a .TAP file.

OK...LazyCam is easy to work with and it exports GCode to Mach3.
But the code appears in the Mach3 file directory with a .LC suffix.

I can see that Mach3 doesn't like .LC files, it wants .TAP files.
How do I convert them from .LC to .TAP?

Also...
Does anyone know how to adjust the spindle speed. There's a drop down tab on the menu bar in Mach3 but it doesn't have any effect on the speed.


Hoping someone can help, 5K down and nothing to show for it.
