Re: EMC Problem

EMC users,

Ian Wright wrote regarding 4 axes in the EMC:

I installed the latest release of EMC (17 Sept) last night and thought
I'd have a play with 4 axes. From another post on the list I got the
impression that by simply changing the 'number of axes' to 4 and by
duplicating the
parameters for one of the other axes in the .ini file, I would get the
required effect but, dissapointingly, the display still only showed 3
axes. I know others have said that up to 6 axes are now supported so,
what else
must I do to get the full display?

The xemc display program will only support 3 axes. The "yemc" program,
which is an interrim test GUI we wrote, will display up to six axes. It
was done to support the EMC on a hexapod machine. For example, in your
.ini file, you can do this:

[TRAJ]
AXES = 6
COORDINATES = X Y Z R P W

to get the yemc to display 6 values, X-Y-Z-roll-pitch-yaw. W denotes yaw
since Y is taken. In the COORDINATES entry you put whichever subset of
these you want and the labels are set accordingly and the proper values
are taken out of the controller and printed.

Note that this is not suitable for machining centers, which use ABC
format instead of RPW. Even with this obstacle, the EMC motion planning
only supports Cartesian XYZ motion at this point, and the interpreter
only supports XYZ.

Summary: wait for full 6-axis motion planning, a G code interpreter that
handles ABC format, and a GUI revision that displays all your axes.
Estimated time of arrival is a few months.
