> How do the regular users do this please? All help is greatly appreciated :) If you are changing tools mid-job then each tool that you are going to use needs to be in a holder. If you need to move tools between holders, then you will find it easier to split the job. I have a turning and facing tool that is designated as tool1 and that always has zero in the offsets. Using the Axis interface it is a bit too easy to mistakenly touch off an axis when you meant to touch off a tool, and vice-versa. If I accidentally put a tool offset in tool 1 then G10 L1 P1 Z0 X0 recovers the situation. I generally jog the tool up close to the work, touch-off the current position to (for example) 0.5mm in the current coordinate system, then face-off to Z = 0. I then take a test cut, measure with a micrometer, and touch-off the X to the measured diameter. That is normally enough, as my other tools have all been set up relative to Tool 1 previously. But if not, then the process is repeated for the other tools, but touching-off into the tool, not axis, offsets. If my home switch was more repeatable then stage 1 would be a one-time thing too. For boring bars I set the Z=0 using a broken 6mm milling cutter rather than with a test cut. Put the tip less than 6mm from the reference face, hold the milling cutter in the gap, and slowly jog away from the work until the cutter pops through the gap (much safer than jogging _on_ to a test block) if your QC toolpost isn't very repeatable then you might need to swap parts rather than tools. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
