ENHANCED: Logic for Post Bend Jog and Radius Shifting in STEP Mode

The Post Bend Jog now works the same in both AUTO and STEP modes during bending - even if the Radius Shifting Mode is set to "During Feed".

Explanation of Issue

The Post Bend Jog was traditionally placed after the start of any "DURING FEED" radius shifting. This caused the bender to operate slightly differently during STEP mode when compared to AUTO mode. The problem with this is:

AUTO MODE:

1. The Post Bend Jog, even though placed slightly after the activation of the secondary DURING FEED radius shifting process, could still occur just before the the simultaneous shifting.
2. This made the process appear to have activated the Post Bend Jog first - even though it did not.
3. This is especially true if a Radius Shift Delay is set to greater than zero milliseconds.

STEP MODE:

1. The Post Bend Jog move would effectively disappear during STEP mode.
2. In Step mode, the DURING FEED radius shifting would already be completed before the Post Bend Jog would be activated.
3. This would create a crash condition where the radius shifting would occur with the tube still in the die.

Solution

The Post Bend Jog will now always be placed BEFORE the start of any "DURING FEED" radius shifting. This is a sample process list with the new order:

[DISPLAY] Next Step: (FRB Row 2) Move Feed Axis +1.0000 IN Relative
FeedPositive = pos0:25.40000000, vel0:694.00000000, ump0:1, cto:60000
