Rotary Engraving
1. Measure and fill in the Object Diameter parameter or the Circumference parameter of the
object. As you fill in one parameter, the other parameter will automatically update.
• To measure Object Diameter, you can use either a ruler or a caliper, but a caliper provides
an accurate reading.
• To measure Circumference, you can use a tape measure.
For a curved-surface object, take the average value of the diameter/circumference of the actual
engraving range of the measured object (the average value of the left, middle and right of the
engraving range position).
Do not forget to update the parameters of the object every time you
change the object.
