I offer to Mach designers, in the future, insert to the Mach possibility of self redefinition and adding self G-codes. As it possible with M-codes.
 
For example  some postprocessors makes G28, G29 etc. I'd like to have tools on VB or other, for write self behavior of this codes.

I think, with that Mach will adapted to many postprocessors.

Thanks. Inna.
