G53 movement

I think that it comes down to whatever the motion control software accepts! However, it does seem that gcode is a bit flexible about this kind of thing. For example, you can put the coordinates in in any order, and I have a feeling that the G53 can be anywhere on the line. From memory, I think I use G0 G53 X~ Y~ because that seems logical to me, but I don't think it matters. That's all true for Mach3 and LinuxCNC, anyway, but some of the proprietary motion control systems might have their own interpretation.

Thanks both, I'll try my program the other way round and see if it makes any difference.

There are other things at play, so this might be a red herring.
