Cool. Does that mean we have CNC F-Bombs now? ;-)

Your Java code should (if at jest could) insert an inverse-time F word for each
move using required linear feed and move length.
I'm not sure of what you mean by the CAM system or if it is relevant to
what I do. Possibly someone can explain.
I write Java code that exports g-code files to run a small CNC router or
CNC desktop mill. I am considering adding a lathe like attachment

The motion controller has no way to know where the centre of rotation is, so it

And the max velocity? Set it up 20x what it is currently, then use the
jog slider to see how fast it can move w/o a stall. Scale that to be the
max accel & scale the max vel at about 65% of that, should give

Could you please check what this does?
G91 A360 X0 F100
this has an X component ( no distance tho )

Its definitely set to angular.

For your check, make sure the 4th axis is set to angular as the
first thing to check in the .ini file.

Len,
You know, being a proud owner of one of your rotary machines, that I am
as interested in this answer as you are. Everyone tell me if I'm wrong, but
won't the feed rate also depend on the distance from the center of rotation
as well. I mean the surscae of a 3" diameter will spin faster than
On a machine with a rotary A axis, if I run
G91 A360 X10 F100
the machine moves 100IPM on the X and the A axis completes a 360
degree rotation at the same time. If I then run
G91 A360 F100
the machines takes almost 2.5 minutes to complete the rotation, because
it is only running 100 degrees
