 Of course it's important to use the proper speed, power and number of iterations for each object to cut.
778 385
 Not enough power or iterations, or too high of a speed, and the object will still be part of the stock material.
779 386
 Too much power or iterations and not only the object will be cut, but also the base plate below.
