2D files

[kolias]

I would like to run a simple 2D program on my router CNC. There are some simple 2D files I can get for about $10.00 and would like to experiment and see the results.

My question is do I need any special bid or any engraving bid will do?

Does Mach3 can handle 2D .dxf files?

MAch3 reads g-code. A 2D .dxf file is just a bunch of lines (and maybe arcs or circles). You need to create g-code from them first. LazyCAM can do it, or any other CAM program.

I'm assuming these .dxf files are artwork, or line drawings? And you want to engrave them? If so, the bit choice probably depends on the material you're using, and what you want to achieve.

Thanks Gerry, yes it is simple artwork that I would like to experiment with. Therefore since LazyCam can make the g-code it means that I dont need any other software, just import the .dxf file to LazyCam, size the drawing to whatever size I want and then Mach3 will do the rest?

Yes I will engrave the artwork on MDF or Pine just to get the feel of it. I thought I read somewhere that I need a special bid to do 2D artwork regardless the material

I don't use LazyCAM, but it should work.

As for the bit, you can engrave with any bit you like, as long as it gives you the results you want.

Thank you Gerry for your time

I think I need to educate myself more regarding the software required to do some beginners artwork because I tried to import a free .STL file into LazyCam and she stopped working. I guess either the file was too big or Lazycam can’t handle .STL files.

Anyway I was searching for some reasonably priced Windows based CAD/CAM software and it seems that Vectric 2D or 3D or Deskcnc may fit my needs.

I wonder if anyone has a better suggestion for reasonably priced CAD/CAM software which will work with Mach3

[ger21]

Depends on what you want to do.

An .stl file is a 3D mesh model. LazyCAM can only read 2D drawings.

Vectric's Cut2D is the most user friendly 2D CAM program.

If you want to cut 3D .stl files, then look at Cut3D or MeshCAM.

For 2/2.5D, you can't beat SheetCam.  Vectric Cut 2D is similar, but it does not do lead in/out, which makes it pretty useless other than for maybe a hobbyist.  Never could understand why they omitted that feature.

ok, now I get it with LazyCam that can only read 2D drawings. I’m sure that the .STLfile I had was 2D but I delete it since I could not use it. Vertic’s Cut2D sounds good but I will also investigate now the SheetCam program which I was not aware.

Basically what I want to do is to make some 2D engraving on Pine or MDF to get the feel on how this process works and it’s all for a hobby.

Thank you both

I’m sure that the .STLfile I had was 2D

.stl files are 3D only.

Before you buy any CAM software, spend enough time to learn how to use the demo's so you can make the right choice.
