anyone using 4th axis ?

Hello,

I have finally upgraded to the latest EMC (20-Dec-1999) and have
been trying a few things.  The biggest problem I had was that the
sense polarity of the limit switches seems to be working backwards
of what I had before (or else, the old version of EMC was ignoring
the limit switches, which could be).  Anyway, once I got those set
right, both xemc and TkEmc user interfaces worked fine.  I notice
the TkEmc updates the screen a bit slower than xemc - not a big
problem.

But, I'm looking at adding a rotary (angular) axis to my 3 linear axes.
I added the block of info for the 4th axis, as well as specified 4
axes, and their names, etc.  I tried xemc, TkEmc and Yemc.  The
first 2 totally ignored the 4th axis, but Yemc left a blank space
under the Z part of the display.  That was as far as it got.  I was
hoping that all the work that had ben done to emc was going to
bring a 4th axis closer to working.

Has anyone else been working on a 4th independant axis?

Thanks,

Jon Elson
