Thanks for the links
Unfortunately, none of the proposed function (M10P1, M11P1 or E1P0, E1P1) does not work on my version of MACH3 (R3.043.066)
I've tried different combinations with axis move but does not work.
If I turn on and off Output1 with M3 it works but too slow
Is it really only one possibility for fast output - phantom axis?
Thanks
