Starting a new thread 'cause the others were getting long.
First up is exporting SVGs — this is working now, except for the problem of SVGs having a different coordinate space from OpenSCAD and DXFs, so when exported, they are mirror-imaged top–bottom — may need to do yet another re-write to allow this to be handled in a reasonable fashion.
Given the difficulties with SVGs, a work-around may be to instead use multiple DXFs — a separate file for each tool should make importing and cutting more straight-forward.
This however, wants that each sort of tool be defined/supported — the current project needs:
small square endmill
small V endmill (same diameter as the small square)
