Problem
PF in-position time-out - The in-position time is the amount of time
the printer waits to make sure the carriage is not moving when the
carriage comes to a stop. The rotary encoder is activate for the
predetermined "in-position time" and if the encoder sends a pulse,
this means the carriage is moving even though it is supposed to be at
a full stop, this generates an error.
