Issue when part of 3D relief is outside model (Maker)

Hi All

I seem to have an issue when part of a 3D relief lies outside of the model.

In this example, I have an ellipsoid feature that cuts across the model boundary partially.



In the model view, all seems well.

To get this in toolpaths, I am using a 6mm Flat End Mill for Roughing, and then a 6mm Ball Nose for Finishing.

But the simulation, simulated view does not seem to cut down on the side as per the above.

I thought about just 'lying' and making the model a bit bigger, but will have to start from scratch as I cannot resize the model itself after the fact (there are another 5 toolpaths that are not relevant to the current issue that would be affected by the re-size).  

Any ideas or suggestions?

Many thanks,
Liam

  • Hi Carveco Support

    Any update on this weirdness?

    I tried to add an upper border:
    1. small one (1mm) - no change
    2. large one (15mm) - cutout shows, but shifts the relief to an unacceptable location.

    Many thanks
    Liam

  • Hi Liam McDermott,

    The result of your Machine Relief toolpath named Gravy Trap is confirmed by the toolpath simulation result shown below: 

    If you then simulate your 2D Area Clearance toolpath named clear-down, the result is as shown below:

    Therefore, the 2D Area Clearance toolpath is removing additional material.

    If you were working in either Carveco Maker+ or our flagship Carveco product, we would suggest that you consider selecting the Machine Relief toolpath named Gravy Trap, then using the Transform Toolpaths tool to nudge the toolpath downwards in Z by 3mm, which is equivalent to the amount of material being removed by the 2D Area Clearance toolpath named clear-down, as shown below:



    The important thing to consider here is to maintain the correct order for your toolpaths during the machining process to avoid an unexpected plunge.

    Without access to this functionality, without making any changes to your CarvingBoard-Template.art model in Carveco Maker, we can only suggest that you machine the calculated and saved 2D Area Clearance toolpath named clear-down first, change the tool, reset the Z on top of the new depth, and then machine the calculated Machine Relief toolpath named Gravy Trap.

    Thanks for your time and consideration.
