Status: offline 		I am working on a cat offshore hull which is 67" lon and 20" wide and was trying to find a source that will cut something that big. Planning on cutting it using MDF boards glued and clamped together alot cheaper then aluminum and still very strong. If someone has a source that would be great. Thanks Rick

Funny that you may ask this now as I am building a custom cnc machine for that exact purpose. It will be able to machine MDF, aluminum, foam, etc in a cutting area of 59" x 36" x 9". I'm not sure what rates I'll be charging, but I do know it will be much cheaper than laser/plasma. Here is a CAD rendition. I can accept just about any 3D CAD format. When the machine is complete, I'll begin a thread and start servicing customers on a first-come, first-serve basis.

Next I have to figure out how it works

Nice Joe2006! Are you running Geckos? Let me know if you need any help getting it going.

Status: offline 		I'm running the RTR Xylotex 3 axis with the 269 oz steppers, Mach 3 and Sheetcam so far. Finished up my hold down board tonight, had the cnc cut all the tracks, and drill the mounint holes out. (Good Practice) I've just got to finish the stand for it, put on the limit home switches, and tidy up all the wiring. But so far its working well. I've made a few other sample cuts if 1/4" MDF, 3/4 birch plywood just to test it out.

What are you going to use for your 3d CAM software? I've been looking at V Carve package.

From what I hear V Carve is pretty good, but if this is your first machine look at BobCAM. Doesn't get more user friendly than that. Right now I'm using SolidCAM (CAM add-on for Solidworks) with Mach 3 as a G-code reader. Works great because I never have to leave the program for toolpaths ans I can simulate the all the cutting operations BEFORE turning on the CNC machine. Previously I was using Mastercam, but it was a little "over the top" for my needs.

Status: offline 		Well I really put the cart before the horse on this little project. I built the machine first, then started looking at software for it, Then picked up a "Student Version of Solidworks" (much cheaper) If I can figure out how to use and get a proficient as you are then I might spring the big bucks for the regular version.

I went with the Xylotex just because they had a RTR version. The HobbyCNC board is nice but I didn't have any inclination in becoming an Electronics expert building it. The Xylotex was plug and play, except for the Mach 3 / Vista part of it. Load and run everything as Administrator or it doesn't want to work right. Take it from someone who knows

Vista? One of my laptops has vista on it. Just sits in the corner until they get all the bugs worked out.

The Xylotex board is nice but when you want to upgrade (you will, did I mention that when you mix CNC w/ RC it's almost as addictive as an 8 ball of a controlled substance?), you'll need Nema 34 size motors that requie A LOT of amps. Look at the Bob Cambell break out boards with Gecko 202's. That's the standard IMHO.

If your interested, I'll be selling the 3D model with dimentioned 2D .dxf files, parts list, and wiring diagram of my machine from the MRM website in a few months. It's all aluminum and can cut metals without a care.

Status: offline 		I've been toying with the idea of doing something along these lines, but instead of getting a CNC plug, Iwas wondering if it would be a good idea to just have a mold made from the CAD file. There are several rapid prototyping companies that will generate parts out of ABS plastic- it seems to me like these could be waxed and used as the molds, without having to worry about parting boards or laying up your own molds from a plug. I think it's probably far from cheap, though with the added cost of materials and time spent making up a mold on top of what you're going to pay for a CNC plug, it may be reasonable? I just don't have any experience with this to know if the ABS parts would have the right properties to be used as molds. Any thoughts?

Thanks,

-J

Status: offline 		As a matter of fact yes, I contacted proto3d from youtube, and he sent me several samples of his work to see if I wanted to go that route. I Have the parts in hand and am going to make a decision over the next few days, I'll let you know.

Status: offline 		I really want to build a machine very similar to what you guys have shown here - there's a lot of information out there but nothing that jumps out as a real, tried and true, leader in a build it yourself CNC kit. What you guys have, with a 48X24" bed look incredible - exactly what I'm looking to build. What kind of costs do you guys have in it (not including software or the computer). What kind of time to build?

Step 1: build the garage...
Step 2: cnc router.

Status: offline 		The cnc machine in this thread is called a Joe2006 and the plans for it are free. Do a search on cnczone. com for more info. I THINK he even offers a pre-cut kit that only requires hardware for ~$300. Costs depend greatly on the quality of the materails used in construction. Total cost ,excluding electronics, are $300-500$ depending on how patient an ebayer you are.

The machine I'm building is a "spare no expense" type of machine made completely out of Aluminum. Costs are well into the thousands
