2D Contour - Finishing vs. Roughing Passes

In the 2D Contour strategy, there are several options for controlling the number and behavior of the passes.

In this tip, we will look at the "Multiple finishing passes" and "Roughing passes" options.

        
Multiple finishing passes: Enable to set the number of finishing passes to perform.

Roughing passes: Enable to perform additional passes before the finishing passes, typically with a larger stepover than the finishing stepover, and optionally with corner smoothing. The amount of smoothing is controlled by the Smoothing Deviation parameter.

When Smoothing deviation is disabled (set to 0mm), there is no difference in the tolerance of the finishing and roughing passes. When smoothing is enabled, the roughing passes may leave leave material in sharp corners, except on the last roughing pass.
