A customer complained that the Die Reference mode was moving the die forward no matter what the state of the home sensor. In their case an important clue was that the die position was a large negative number, -21480.860".

A code review of the die reference function revealed the problem. The forward target was 1000.0" and the reverse target was -1000.0". Both of those targets would have resulted in a forward die motion when compared to the current die position.

The code was modified to prevent this condition by calculating the forward and reverse targets using the current die position.
