For the last couple weeks, running the 2.8.0-pre# my tool, a .250" diameter mill as shown in the tool table, has become a single, weakly flickering pixel that is very hard to follow in the backplot, and extremely easy to lose track of.
The command is M6 T1 to switch to it in my code.

Or are these measurements now being interpreted as mm's? Just for S&G, I'll edit tool 1 to be a 6.35mm (.250") tool when I get back to that machine. Side comment, FWIW: Much of what I use lcnc for in woodworking is 2D, and I find that the 3D display, like when doing multiple passes to get to full depth, of a wood joint where the tool path is just being duplicated per depth pass, is needless dirtying of the backplot display, so I would suggest disabling this feature when an individual axis is chosen for the displayed backtrace. I think its ok for the default angled view, and may be helpful/informative there in helping to visualize things. Using the first Z view, having the displayed trace shrink as the tool descends, is not helpful. In fact it has made me check my code for unwanted, typu driven scaling errors until I realized I was looking at a 3D view from straight up, apparently from the homed, fixed position. Z home for me is near the top of the post so the scaling effect isn't huge, just enough to muck up the view. Perhaps this 3D mode could be made switchable in the view menu? Hypothetical question, throwing it out to see if it sticks to the wall: If I was to mount a dovetail bit, how would that be entered into the tool.tbl? An inverted cone, with a minimum diameter shank sticking out of the truncated tip might do, but to be precise, would need to be able to specify the angle of the dovetail, usually 7 degrees but I have seen up to 14 degrees. That large invites sloppy work though, and does nothing to enhance the strength of the joint when wood is the medium.
