Perhaps? If all the tools measure off, but consistently off, then maybe you'll come out ahead :-)I do notice if I check or remeasure tools before a run I find small differences due to temperature or whatever . Having this done on the machine at run time with a tool setter seams like it would mitigate this a little.
I'd expect a tool height setter to be about as accurate as the end stop limit switches -- one or a few thou' off on a bad day?
They work totally differently, hence why they can deliver different levels of accuracy at different costs.I would expect it to work as good or better then the 300.00 height gauge system.
Anyway, I like me some convenience (and got me one of those ITTP probes, which I'll write about when I have more experience with it,) but the tool setter never seemed worth it to me. Manual entry works great!
Sometimes I take the tools back and re-measure them and they're within a thou of what I entered, so... good enough for me!
