If your Workflow includes MakerCAM you may want to find another CAM solution as Flash is about to be “Sunsetted”. It is unclear if there will be any replacement of MakerCAM.
Alternatively you can set up a copy of Flash and MakerCAM but at some point OS updates will probably kill that too. Flash is seen as a virus on certain levels so you can expect it to be Disabled upon Sunset by the manufacture.
