To correct this, confirm that the encoder is working correctly.
C':3%9'9(*>%';2''3'3
This warning appears if there are too many customized beads (stitch, dot, or
modulated) on the line. The pattern controller has a pre-determined limit that
has been exceeded.
To correct this, increase the interval or pitch (distance from the start of one
sub-bead to the start of the next sub-bead).
D3B'E#(E'3B'%';2''3'3
This warning appears if the distance limit from one edge of the bead to the
other edge of the bead has been exceeded.
To correct this, make the beads smaller, make the gaps between each bead
smaller, change the encoder gearing, or decrease the GTO.
