I have been looking for a CAM program, to create the GCode for my MF70 CNC mill. So far I have found:
PyCAM: The PushCutter and DropCutter milling strategies seem to work pretty nicely. Unfortunately the contour cutting is more or less unusable. It's quite buggy in 0.5.1 and in 0.6 (the latest sources) it forms the cutting path from the PushCutter grid, which means that to get a accurate path, you have to set the overlap to a very large percentage and the calculation takes forever. And even after that, the contour (waterline) cutting only slices the model at fixed intervals. There is actually no way to get it to cut the actual contours in the object, the cutting is only done to where the lowest slicing level on that contour happens to be.
HeeksCAD with HeeksCNC: The contour, adaptive roughing and pocket milling operations look more promising than PyCAM's. Unfortunately this is a pain in the butt to setup and on my computer it crashes about every two minutes. The precompiled packages don't include the necessary libraries to actually produce the CNC code.
Does anyone know of any other usable options? Free, or reasonably priced?
