There was a bug with Delay After Shear when any rotary style shear was configured to Stitch Parts by omitting shears.

The Delay After Shear occurred but it occurred just before the cuts instead of after. On a pre-cut roll-former this resulted in the delay occurring while uncut material was captured by the roll-former instead of just after the material was cut.

This was caused by the Delay After Shear state machine that is unique to Rotary style shears. The state machine delay is initialized by the shear cycle that the delay is supposed to occur after, however, the actual delay is started and completed by calling the state machine during the next shear cycle.

The state machine was not being called by the code that simulated the omitted shears. This resulted in the actual delay being processed and started by the next actual shear cycle just after the last omitted shear was done being processed.
