Hello
Does anyone know what G28 means, in use with Mazak machines??

I,m no coder, but in EIA it means return to No1 home or reference position, as in G00G28XYZ0. G00G30XYZ0=Return to No.2 home or ref. pos. In Mazatrol you just specify the axis to be returned?

As Leelund said, it means reference return position 1. Basically, its the machine home position in any of the axis you comman. However, make sure you are in G91 when doing this like:
G0G91G28Z0
Most programmers will seperate moves to avoid crashes like this:
G0G91G28Z0
G28X0Y0.
It's just a part..... cutter still goes round and round....
If you command a position other than 0 it will move to this intermediate position and then 0.
I believe this also applies to Mazak.

G28 = Return to home position via a programmed position from your datum.
G28G91X0Y0Z0 will move to home via an incremental move of zero.
G28X0Y0Z0 will move home after the cutter has moved to absolute X0Y0Z0.
Another way to explain the same thing.
