Thanks Seth - Creating in 2.5D with a 3D inset is an option - however Ideally (for grain continuity etc) I’m hoping to avoid this. I’d love for easel to be able combine 2.5D and 3D in a carve (In your experience is there a SW alternative that would?). That way I wouldn’t have to create the whole design in 3D in Fusion 360.
Watching the machine in action, 3D doesn’t include the edge cleanup carves in the same way that 2.5D does. Thanks for the article too.
Hi Wayne - It was designed in Fusion 360 and imported as an STL into Easel, so the whole project was carved as a 3D project. The Roughing bit didn’t carve to the edge of the design, but left a margin that was then trimmed out with the 1/8" ballnose.
The photos you showed, on the sides it has a lot of movement and steps.
-Check the preview on Easel. If that shows you what you got, so the toolpath is wrong. Reduce the stepover.
If that does not change the design, check the gantry and the wheels are tight. It happens to me after several hours of use it started creating that problem because of an loose screw.
-other option: Try to generate a G-code of your model from Fusion, and use Universal G-code sender. That doesn’t fail.
-If you still have the problem, the STL file could be the issue. Try to increas the size of the mesh of thay model to smooth out the edges.
Some design software has problem generating cirles as a continuous line. For example on sketchup, a circle is generated by several faces, and when it is carved out on the CNC you can see the small faces not a continuous line.
If you still have the same issue, create a 2D toolpath profile with a straight upcut router bit, so you will have a smooth edges.
Thanks Ulysses, what I have ascertained is that Easel does not allow for 2D profile cuts when working with an STL - all work along the x axis commenced with a plunge cut using the roundover bit - hence the scallops - reducing the stepover helps, but at the cost of time.
I’ve now moved to Fusion 360 and g-code so I can create appropriate paths for the design to ensure smooth profile edges.
