it's nice to communicate with smart people
It's done already. The right way is setting of faulty parameters using system check mode. I did other way - discovered relevant parameters (only two of them) and by method of scientific push adjusted machine axis somehow :-)
By the way. Spare parameters are usefull only when machine axes are in the same position:
magazine chain (tool pot at retract arm); crossrail (M199 ... M190); tool arm (side A or B); all intermediate tool pots; spindle indexed; and, of course, attachment/ adaptor cradle.
