Kirk, Thanks for the reply, I can't decide whether to implement it as ClassicLadder or a .comp file.
However, I have discovered a more critical problem. When I run a G95 move I don't get the correct pitch. This happens in Mach3 also which is why I set off down the EMC road in the first place, to see if it was software or machine specific. I do not get the problem on a desktop machine only on my laptop. I found it interesting that both Mach3 and EMC produce approximately the same incorrect pitch with G95 moves. Obviously until I either fix the pitch problem or change the computer then my machine is useless for threading! FWIW if I command a G95 G1 F2 Z0 from a Z-70 position then the resulting pitch as shown by a very shallow cut (scratch) then the pitch over 33 pitches of 2mm = 68.2mm measured using a Mitutoyo digital caliper.
