Lathe Macro execution was created by JuFu
Hello, I did CNC (retrofit) an old Magdeburg D30 lathe.
Started wit AXIS, but changing to gmoccapy now.
Included Lathe Macro and it seems to work (so far).
here my question: when I parameterized a Lathe Macro, how do I get it executed (the lathe to move as wished)?

Thanks for the fast response.

If you have a low resolution screen, the play button will be hidden.
There should be a topic or two here about how to fix that.
Sorry, but on the phone.

Is there any chance to see/read the nc-code generated by Lathe Macro?

It doesn't generate gcode. It calls the respective ngc subroutine and passes the required parameters.
eg 'turning.ngc':
