Hi Gene,

G8 is hard coded to work on X axis. It doesn't really make sense for any other axis. Could you swap the axes in your config?

Lathe uses X-Z because lathes are essentially treated as milling machines on their side. By convention Z is parallel to the spindle axis.

Greetings All;

Because the G5.x stuff hasn't had much TLC (probably from lack of general
use by the artisticly inclined among us) since it was intro'd back in
the mists of time, and is locked to x/y only motions, the thought has
come to mind of creating a special config where x is carriage motion on
the bed, and y is crossfeed.  Essentially duplicating a milling
machine's xy motions.  This is the easy part.  What might be surprises
are the g7-g8 effects, which work on the x axis, and that would not be
ideal. So G8 s/b hard coded somehow.

Next of course would be touch-offs, but if the config is done right,
should not be a problem.

What surprise gotcha's would I be likely to find?

Was there some overriding reason the default lathe configs weren't done
this way in the first place?

Cheers, Gene Heskett
