Looks like I'm not the only one with ambitious plans. vertigo

How do you actually get the sizes and shapes to put in program for the machine to cut them out

The files are made 1:1 size. I double checked measurements against the Möbius model and it seems right. The CAD program I use has an option to set scale. Since I am reducing size by 12 percent I just set scale to .88 and it's golden.

I’m very computer illiterate. Do you scan the car to get the shapes. Sorry for my dumbness haha

No problem, sorry I wasn't clear.
I purchased the design file from a company that produces 3D graphic files. I believe they specialize in making 3D designs to be used for making props, etc. You need to let them know what type of program you want to read the file, then they will send it to you in that format. For example, if you are going to use a 3D printer you would want a different type file than you would use for a CNC routing machine. For the CNC machine you need a CAD program for the design, a CAM program to create the tool path for the machine and generate the g-code that the CNC machine can read, and a program on the computer that runs the machine (like mach3) to read the g-code and translate it into actual commands to move the motors along the tool path.
Complicated? Yes, but once you get use to it it's not as tricky as it sounds.

Cool thanks for that info. I want to start my tumbler again but I want to get the panels 100% correct instead of using a ruler and protractor.

I think someone on here has CAD files of the tumbler they sell. If not, I bet they're not to hard to find online. Might cost a few hundred, but worth it if you're a serious builder.

hey sly,
What diameter, length, number of flutes, end or ball type, did you finally end up with to cut the foam for your milled DOJ body foam? vertigo

I'm doing everything with quarter inch up-spiral square end mills. Half inch for rough would certainly go faster and eighth inch for finish would be cleaner detail, but I'm very lazy and that would require changing bits.
From my feeble memory I seem to recall length of bit is 3.5 or 4 inches and length of cut is 2 or 2.5 inches. Two flutes, Solid Carbide long reach foam cutting bits. I tried the HSS bits but they didn't hold up well.
That being said, I found my original idea of gluing two 2" sheets of foam board together and milling them as one was too awkward for the homemade machine I built. Much easier to just do it in 2" layers and glue them together when done. A professional machine would probably have no problem with it. Problem is, on a wood and gas pipe machine, using that long a bit causes enough flex to make the cut inaccurate.
