#455 holds what?

edelec

Currently deciphering G28, what does #455 hold, it is not listed in the macro variables.
Thanks Richard

I don't know surely.. May be that CNC asks in what coordinate system it is? From G53 to G59.

Yes now analysing the code it does appear to refer to the different cordinate systems, but that is what parameter #16 (#516) shows, not sure why in two places or if different.

Maybe cnc takes the 516 parameter as the INITIAL value of setting # 16 inside ENG file .. And not the current coordinate system modified in gcode, but i do not know exactly
