With the 4.28.14 update, a motor movement monitoring feature was added that can help you find the source of obstructions, and monitor your motor movements for speed and detail settings. To enter the motor movement monitoring mode, go to Main Menu->Utilities->Preferences and turn the Motor Movement Monitoring option to ON. Once you have changed that preference, anytime IQ is stitching or previewing a design, you will have a new item on your toolbar "Show Trace". When you click on this ribbon button, it will change to "Hide Trace" and the trace feature will be active. You will see a black line representing where the motors were actually able to move the machine and the red line where the program desired to move the motors.
