It is easy to mess up. > I can vouch for that, for some reason I still get confused from time to time touching off tools and G54. I usually use G55 to touch off tools. BTW, the DRO screen in master is very valuable when touching off tools. I use the dowel method as well on the CHNC and it works well for those tools that can be touched off that way. I have developed the habit of loading a new tool and double checking that my Z0 is where I expect it to be and I can tell well before the tool crashes (from experience) that the path is not correct as the tool flies toward the material in the chuck LOL.
