Will wood density and knots affect the cutting performance?

The short answer is 'yes.' Varying material densities and irregularities can affect your cut quality with Origin—we're not changing any laws of cutting physics.

One of the nice things about being involved in the cutting process, though, is that you’re able to see and/or feel anomalies and make adjustments as needed and on-the-fly. This means that you can change feed rate or cut depth the moment you notice the resistance that signals a knot or increased material density.
