The CNC Router Parts post processor is basically the same as the Mach3 post, with an M7 to start a dust collector.
With a program from Aspire, The X & Y zero is at the far right end of the table. (Spindle facing me) On the Next Wave machine, it was at the forward left end of the table. If this is normal, then I must live with that Is this normal??
If you are referring to the home switch position, then it doesn't really matter. The "Home" position is in machine coordinates. When you cut parts you use work coordinates, and set the XY zero for the work coordinates wherever you want them to be.
But if I run the G-Code with the spindle running, it misses 100-150 lines of G-code.
What do you mean by "missing g-code"? Is the machine stalling?
