Description
The gun tip position during the pressuring operation (SPOT or PRESS_MOTN) exceeded the stroke limit for the gun. The squeezing operation stopped because the gun axis had over-extended.
Remedy
Check the master position and close stroke limit for the gun. If these values are incorrect, then update them. If these values are correct, then install new tips so that the gun can operate within the stroke limits, during pressuring.
