Hi ranchak~
If you'll allow me to comiserate - Sounds like I'm pretty much in the same boat, but I think we're on the right track. I haven't ordered a single part to build my CNC yet - I'm in the information gathering stage. From past experience I found that what will work best for me is to get the learning curves mastered (not so much fun) before I build the machine (fun). I don't want to build a nice machine only to find that I've made mistakes in my choices about how I'm going to run it. So my learning path will be: 1. Play with the software and learn its limits (or mine, ha!) 2. Learn about the electronics interfacing (drivers, power supply, etc.) 3. Apply what I've learned to making the actual machine.
I was on 'Build Your Own CNC Router' (
Build Your Own CNC Router Machine) site recently. Patrick, (the CNC guru there) has experience with, and recommends Solid Edge 2D and Mach3 CAD/CAM software for an 'entry level budget'. (He
prefers AutoCAD but I'm in no position to buy that) I've already downloaded Solid Edge 2D and was pleasantly surprised at how robust it is. It's important that whatever the CAD software brand, it needs to be able to convert/import .DXF files and also save .DXF files/revisions, which I believe are required in Mach3 to produce toolpaths. I haven't yet downloaded the Mach3 demo software, but I read that you can disable the printer drivers and work with it 'experimentally' to learn about how it works - sounds great to me! I also read that the Mach3 demo will limit output to 500 lines of G-code, so it's actually able to be used with your machine so you can evaluate it in real time.
CAMBAM also sounds like it holds promise - I simply haven't made up my mind yet about all this stuff and need to do more research before I spend my hard-earned money for licensing.
Back to SE2D...'Yes', there is a learning curve. 'No', learning curves are not the most fun thing to overcome, especially if you're feeling rushed. I do have some limited experience with other CAD software. I went through the included tutorials and like what I see and believe that it will work for me. I could easily go to the table and draw out plans for my guitars as I've done for many years but I'm trying to think of overcoming this learning curve as a worthwhile investment of my time. It's been said that anything worth having is worth working for...
I do feel 'better' about this after reading testimony from Patrick, who has used it successfully and speaks well of it.
I know that I'll be in for some frustrating moments solving problems while I learn how all this stuff works, but I'm trying to keep a positive attitude - If other people can do this - SO CAN I! I know that I'm not alone.
Everyone starts at ground zero and
everyone has the same concerns as you do, so don't get all hung up on the little things.
You can do this! Seimens has a newsgroup, user forum, and other tutorials.
You can also import other CNC .DXF files, for instance, "Download JGRO’s Design in DXF format" (
CNCzone.com-Machinist Community Forums - Welcome Page - Welcome Page) to speed up learning.
IMHO, observing what others have done is a great way to learn. I downloaded the JGRO files and have been fooling around with them in SE2D. This is cool stuff!
I don't know if any of this helps you or not, but you have both my sympathies and my best wishes going forward with this. At least you know you're not alone in the boat! Ha!
