When doing a multi-pass carve (depth > depth per pass), the Z plunge always occurs at the same position. This can result in an aberration (defect in the carved edge) where the plunge happens.
What I’d like to see it do instead is perform a “smooth” z transition through each layer, by distributing small Z changes throughout the entire pattern on one pass, and then continue until the last pass which holds the final Z position at the desired cut depth.
This would basically eliminate the Z plunge entirely, although it would require an extra pass at the end, by spreading the Z plunge out over all the prior X/Y movements. Basically, the carve would start at the plunge point with a Z0, and then slowly move Z down as it carves the pattern back to the start point where it’s now reached Z at the depth per pass, then continue on without stopping.
This would completely eliminate visible marks on the cut edge from the plunge point.
