Well after using using my home built machine for years, I now find my self a little confused
My X axis home setup is Soft max =310 soft min = -310 Home off = 310
So if I issue G53 X0 this places the X Axis dead center of its limits
If I then enter G54 G92 X0 I would have assumed the G54 X offset would read either 0 or -310
but it actually reads -358 there are no tool offsets and the tool number is set to 0.
Maybe I have early dementia setting in.
Can somebody shed some light on this thanks
