I’ve already carved one using the linear cutting option in estlcam’s 3d machining interface. But it seems like the correct way to do this is have the tool spiral down. However, when I use the waterline machining option I get weird disjointed paths like these:
I’ve experimented with different settings but can’t figure out how to get rid of these. One guess is that this is coming from using an stl to represent such a gradual curve. Any other ides of how to get estlcam to generate a non-disjointed tool path?
Great question! I have a similar question and also seek likely a related answer. This is not yet at the top of my list, but I’m very curious about this process. I have a piece set aside for this operation once the workflow is clear. It will be 2 sided though and that is another complication in an of itself.
@christian-knuell does answer here i have not tried the paths you are treading on yet. I’m not sure how often he checks here maybe try the estlcam site and see if he is there also if he answers there we would like to know the answer also
The v11 (Automatic Functions >) Solid of Revolution isn’t perfect, but its ability to spiral cut any shape from half a 2D cross section is pretty handy/cool.
To simplify my earlier post: Set inside only Machining diameter to ‘cut diameter - tool diameter’. Remove the end of the finishing block/program clearance plane move and all lines up to the second to last clearance plane move. While they won’t do serious damage, they are out of bounds and the Z0 DOC can leave a very subtle mark on the uncut surface.
Solid of Revolution (SOR) always has a center of the project origin and the easiest way to do any two sided project is to use four locating holes/dowels an equal X,Y distance from the project origin. A drawing with the holes and a part perimeter circle is needed to drill the holes and cut a tabbed perimeter part path. One flippable (in Estlcam) or separate top/bottom section drawings are needed to generate the SOR G-code.
Without grid holes/vacuum, the easiest way is to drill holes in the spoilboard and then in the top of the mounted material, cut the inside of the bowl, insert dowels, flip and remount the material, Depth limit the bottom SOR cut to leave a bit of material and finish the cut with a tabbed Part path. See EstlCAM 2 sided cuts - #16 by dalrun for a 2x 3D example.
