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
-
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

.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.
-
If you want to fool around with a 2d file you can use the one i have posted in the members docs for the Lazycam Manual.
If you want to engrave then just select the whole thing or parts of it and define a small depth of cut.
I will echo what Gerry said about CAM software as their cost is high and increases with what the software will do
and what it provides or is included. Have a look at Vectric product comparison and compare to other software to get a flavor.
I just started using MeshCam, like it, and as it suites my need, but, i also have other software which complements it.
What is good for one can be totaly wrong for another user. Time spent on a 2d package will not be wasted as the experience is directly applicable
to more complex machining.

Hmmmm...... another thing I didn’t know among the many other ones LOL......
So if .STL files are 3D only, what the 2D files are? maybe .DXF?
Very good point Gerry and I intend to do so but there are many CAM software and I prefer not to spend the time with the demos of each one because I will get confused. I would rather choose a couple or so and then get the demos and decide.
-

Every CAD or drawing program will have their own specific file format.
For CNC purposes, you want a file type that contains vector information.
.dxf is the most commonly used, because most programs can open and export .dxf files. The .dxf format was created for this reason.
Some CAM programs can read many different file types, some can only read .dxf files.
-
If you're looking for artwork in dxf and g-code format you can try the "share your g-code" topic on this board.
http://www.machsupport.com/forum/index.php/board,61.0.html
Not sure how to make that a link. Guess you can cut and paste it or just go back to the main board menu and look for it.
Someone there also has a link to a website with hundreds of free dxf files of logos and simple artwork objects.

Well I learned a lot today, thank you all
I missed your post Rich before; I will work on that 2D file, thanks. BTW is this file the “Mill LCR0 HCIR.dxf?”
I had a brief look at the MashCam site and looks interesting and I will investigate further. You are right, each one of us have their own likes & dislikes when it comes to software or anything else for that matter.
Sage that’s a good tip and I will have a look at it, thank you
