Thank you for that link Andy, I found when I scrolled up by accident to the previous entry, what may be the reason I have been doing my own tool diameter offsets in my gcode I have written. I have never been able to get consistent results from a tool change operation. The problem that may be the cause of the inconsistency? I do not have TOOL_TABLE = tooltable.tbl such a line in my current .ini file, and may not have one in any of them! The save operation that allows a new profile, like my-mill-test, to be written, apparently does not define that, ever. Could this be construed as a bug? I certainly was not aware that a tool could be described in that much detail so it will take me a bit to wrap my remaining wet ram around it, and to get something entered that might make sense to emc. Unforch, my toolholders are #2 morse collets in that teeny mill, so the working lengths, unless measured after tightening the draw bolt each time, are completely random. And that brings up a question?: Do we have a function that could be written into the gcode after a tool change command that would probe the tool like G38.2 does and record that length offset and use it till the next run restart, or till the next tool change? That would open the door to my being able to switch cutting mills mid-job, and would expand the view of what I can do considerably. Is there a link that allows this whole thing to be downloaded as a pdf? Ahh, I think I found them, but broken into user, hal etc. My dead tree 'manual' stuff in the shop is about a year old & likely out of date as I have been letting the package manager update my emc install each time a new release is built.
