G4 pause after a G1 move

May I suggest that you experiment a little with G64 as well. You may be surprised how much faster a file may run with say G64 P0.001 vs G61 on your machine without appreciably sacrificing part shape, and possibly improving surface finish and tool life through better speed management.

Thanks Todd I will certainly give it a go. I keep learning new ways to do things, soon I might even know what I'm doing
