Thank you for your request.
Would you mind sending your files to gtac, so that we can investigate this case?
One thing you could additionaly try is using Simulate instead.
You can do that even without having a machine loaded.
with NX103/NX11 you can change the Minimum Simulation Time within the Simulation Settings in Manufacturing
Regarding the Minimum Simulation Time there are some background information:
The “Minimum Simulation Time” (MST) value is used to indicate how often a display update happens during simulation if speed slider is set to 1. The formula for the slider setting is like:
MST * 2^(n-1) - n is slider setting.
MST need to be a multiple of the cycle time.
The initial MST setting is within the kinematic model. To change this, open the kinematic model in Machine Tool Builder. Open Simulation Settings Dialog in Navigator (RMB)
