Ramping Pocket ToolPath Curiosity When Z-Zero Is Stock Bottom

Was prototyping a small design when I discovered a weird thing about Pocket toolpaths with ramping enabled - with Z-zero set for bottom of stock the toolpath wants to start way above the stock thickness(possibly twice the height of stock thickness?).

Changing the Z-zero to top of stock & the toolpath starts at the Retract Height above stock thickness as expected.

Seems like a stock height 2x mulitplier got into the code for what Z the path ramping starts at which greatly increases the cutting path length/time.


You’re not the first one to notice this issue.

I’ve been told it’s on their radar, but I’d still file a bug report to bring more attention to it.
