G30 programming

[Leadhead]

Neale - Thanks for reply. I am actually just beginning to use Planet CNC TNC. (Still have three other Mach3 M/c`s) Just to confuse myself. - Been experimenting with G30 and it is becoming clearer. Absolute XY position and Z sequence for clearance are set as normal and as you suggest this works conveniently for a fixed sensor plate. - But I still would like to understand the multiple G30 offsets. Going to "play" with it this morning by trying a G30.1, G30.2 etc.
I guess it might be used as zero offsets for multiple pieces on the table or multiple non uniform part positions on a single plane?
Just something I have not use before and as Planet CNC feature it, curiosity more than necessity has set in.

Interesting. I haven't used G30 (used to have a LinuxCNC machine but now using Mach3) but the documentation I found all seems to talk about G30 (to go to preset position) and G30.1 (to set that position). Maybe the Planet dialect of gcode adds further G30.n settings? If so, not sure how you get access to them! Please update us when you've worked it out
