Bad idea IMO, to change the default behaviour, likely to catch some people out good style ;) Personally, I mostly use EMC with my lathe. All my tools are referenced to my "master tool" T1 which has no offsets. Any touching off is done against the stock after taking a cut and measuring. At the moment I'm using quick change tool holders, so the tool offsets are repeatable. I make manual adjustments for tip wear. Hint <G> Be nice to have wear offsets in the lathe tool table and an easy way of setting them so as not to affect the default tool setting when it has a new insert fitted. I have a changer for the lathe, but haven't got around to setting it up. It's one of the "Denford" type worm and ratchet changers, where a stepper winds it on, then back to stall the stepper against the ratchet. Works remarkably well, locks up solid and can change from T1 all the way round to T8 in well under three seconds reliably. Again - with that, tool 1 would just get touched off against the stock. Take a facing cut, Zero Z, take a skim off the diameter, measure the result, touch off X and add that value in the box and it's sorted. The initial setting up of each of the other tools is done pretty much the same way. From experience 6 of the tools have a permanent home, the other two positions may change depending on the job. I also use EMC sometimes with my router. That has a high speed spindle with collets, unfortunately tool length is not repeatable and I tend not to use the tool table at all. All the entries are 0. CAM looks after the diameter of the tools, all tools are touched off on the top of the work and Z is then zero'd.
