yeah, that is what I did attached thew board against the front of the machine where my spindle could still reach it and there I cut my real dovetails. but that was with trial and error and lots of waste material to try it out. Kind regards Hans

I need a way to create a contour Toolpath for cutting out plastic vacuum formed parts on my CNC. Here is a short Youtube video which shows what I am trying to accomplish:

I need a way to create a profile Toolpath that has a variable Z height that follows the 3D shape of the outside of the part to cut out.

Is there a gadget, or could a gadget be created to make generating such a Toolpath possible?

Yes there is. You need to import the model of the shape into VCarve/Aspire, create your cutout vector (use the Create Vector Boundary tool) and then create a profile toolpath from that vector but make sure you have the Project Toolpath onto 3D box checked in the toolpath.

The toolpath will then follow the contours of the shape "underneath" the profile vector.

hello i would like to create a gadget for: selecting an imported file, and rotate 90 ° ,and then set it back to x 0 y 0. is there anyone who can help me i'm stuck on the point rotation and set it back on x0 y0

Assuming it is vectors you want to rotate you need to look at the Transform method in the SDK documentation.

Good morning everyone. I'm getting a 3 Axis CNC with vertical and side drills for cabinet making. Software supporting these ist extremely costly (8000+++ EUR) and most of the time i use Aspire for Vcarve, and other engravings. I don't want to change it. It's great. using the side and vertical drill shouldn't be the problem, the problem is the toolpath.


Because the drill has an offset, determining the position is no problem, what would be the problem, would be that the drill should have a toolpath, entering from the side and getting out from the same position (or maybe 0.01mm movement) before rising. I saw it made manually (creating some kind of an upside down "U") and it worked.

doing this one could also add a Lamello function, so getting inside rising 1mm lowering 1 mm getting back into the middle and outwards.

If that function would be able also for vertical.... like cutting an upside down "T".


What do you think about this? Manageable?

Here is an idea for a gadget (maybe; I'm not sure what gadgets can and cannot be programmed to do).

The purpose of the proposed gadget is to avoid "cutting air."
Picture a wood blank that is stairstepped (progressively smaller x/y dimensions as Z increases--how most guitar neck heels are assembled). The existing rough/fine 3D toolpaths must cut the entire x/y area, regardless of whether there is actually any wood in that area as Z increases. So when the model tapers up into Z areas where the x/y area to be cut is quite small (e.g., the smaller stairstepped pieces of the "raw" guitar neck heel), you spend most of your time cutting air.

It would be a big improvement if Aspire could somehow recognize areas of the model where there isn’t any wood to be cut. In other words, to allow for smaller x/y material size as Z increases for toolpathing purposes.

If, for instance, a gadget could permit a "ghost" toolpath to be run that fictionally cuts away the wood that isn’t really there (because of the stairstepping), and, because of the gadget's "ghost" toolpath, (loaded and run before the "actual" R/F toolpaths) the “rough/finish” 3D model toolpaths then recognized that wood was “gone” and didn’t need to be cut, that would be a big improvement.

While I provided the guitar neck example because I happen to make guitar necks using Aspire, I am confident there are many other situations where this tool would prove to be useful and a great time saver. Thanks for considering.
