Marcus; Thank you for the tips.
You could always do a manual test (and apologies if you have already done > this) by manually setting the G54-59.3 origins by moving and touching off > each in turn. You should then be able to go to each origin in turn using > G55 G0 X0 Y0 Z0 and so on. > What happens then? > if I set different z depths via touching off, then (eg) G54 g0 z0 and G55 g0 z0 I go to the z depths as defined as 0.0 for that G-origin. Now for the solution: > > I can't see it affecting your method, but I find G10 L20 much more > convenient than the L2 version of that command.

When setting the G55 Z depth for tool touching material, the 9 fixture points follow down the Z axis if the G10 L20 is set, rather than the "L2". I'll have to figure out why touching off G54 does not change the position of the cut in Axis, but G55 does. > Is there a G92 in effect anywhere? > What happens if you put G92.1 at the start of the program? No, there was not, and I don't see any change if a G92.1 is there or not. Obviously, I've lots of reading and button clicking to do, but thank you for the help, especially the L20 rather than the L2 - I think that would have taken me a bit of time to find. John A.
