Hi all!
I’m trying to 3d carve a small indentation for placing an egg on a plank:
When I turn the 3d model with flat side up I get this:
When I flip it, I get this gcode:
I want the carve to be with the last shape, but zero is on the wrong side?? What do I do? Im baffled..
Is the zero on the wrong side? It should be at the top of the workpiece, right?
BTW, Stewart made a tutorial on carving a two sided bowl carving in kiri:moto:
Yeah, Zero is on the wrong side, but when I flip the model, the gcode turns strange..
Don’t you need to specify the shape that is left for 3D carving?
To me it looks like you have a model of the material you want gone, but you’d need a model of what’s left.
Thank you.
Again. Thank you. This is so obvious. Haha, sometimes the answer is right in front of your nose 
If its a circular indentation the V11 Automatic > Solid of revolution is worth a look (any 2D cross section > 3D spiral cut). For a 3D STL I would use a 0 margin and a waterline path for both roughing and finishing.
Oh, now I think I understand the problem. You don’t want the blue thingy to be the object but a hole?
Then just create a round object in the design software of your choice, import your shape and make a substract. Should work with any of the programs. Then you have your indentation as the 3D shape.
The way you are doing it now you are trying to get Estlcam to read a positive as a negative space I guess.
I got it to work! @Wittiko was right. I also needed 0 margin. The carve still made a small “brim” that left some slight marks, but raising z 0.1mm circumvented the issue. Thanks a lot!

Doesn’t it feel great to be making functional items with your machine? Woo hoo!
Oh yeah, if I’d read all the answers I would have seen that… 
Don’t forget to mark his as the solution. 
Ohhh!! I really only saw this as a huge bowl. This makes so much sense now. I wondered why you specified egg.
