INTRODUCTION TO PROBLEM SOLVING
While optimizing profile parameters can eliminate many problems, it is often useful to monitor a print so you can continually

Reasons to observe a print:
• Some parts may require attention and adjustment during the print .
• Your profiling will become more accurate through observation. As your profiling becomes more accurate, the need for
future observation will become less frequent .
