The RF Technology's ability to almost instantly switch to different power levels, makes it well suited to creating a variable depth scan line. Add all these scan lines together and proper 3D engraving is the result.
I have successfully mastered the process on my glass tube machine but the PWM manner of tube control used by the RF technology appears to offer different challenges.
I explained the process of "burning" wood with a laser beam in the previous session and showed that with well chosen parameters it was possible to excavate a significant volume of wood and NOT leave a charred surface behind.
