I only have books back to M+ but Mazak is generally pretty good about keeping parameters for Legacy... check these ones out and test them (but play it carefully!)
F93.3 = 1
(tool length of Tool Data for EIA valid)
F94.7 = 1
(tool offset of Tool Data for EIA valid) this is for comp
F94.2 is for what the control does with the tool length on a G28 or G30 command. I always have this set to "1" to remain valid. The reason why I do is because i typically will retract to HOME (G28 or 30) before things like indexing a pallet, indexing rotarys, moving to another part... whatever. This way, the tool length remains in the control buffer for those next moves. Otherwise, I would need to command the G43 again (or force a G43 if not in code) because the HOME retract command would otherwise dump the tool length offset.
