13 hours ago Kiri currently runs all operations one part at a time. So if you have parts A and B each with two ops using different tools, it will process A1, A2, B1, B2 meaning 3 tool changes. To avoid this, you can merge the bodies of the two objects into a single mesh. To do this with Kiri, use the mesh menu and either merge meshes (into a single part), or export mesh which produces a single STL or OBJ from the existing workspace which you can then re-import as a single part.
If you import a model and setup operations with tool changes, then duplicate the part after the operation setup, then the tool changes are stuck in the g-code even after removing the operations are removed.
