A test plot of 10,000 "dots" using the new pen holder
The new holder is SUPERB!!! The dropouts in the lower part
of the test plot is the pen's ink just getting started.

You can see that the robot does not actually know where the
tip pf the pen is. I need to create the correct "tool" transformation
matrix since it thinks it can draw a little line when I ask to
have it draw a dot.

THis is part of a 100 x 100 array of dots 1mm apart.
It took several hours since I mive at 20mm/Second and 10mm/Second
during the plotting
