Here is a video of my CNC just doing a trial cut.

I must say I didn't know anything about cnc before building my own machine and it sure helps understanding how cnc works. This video was made right after I completed this cnc and since, I have tuned it up so it travels a little over twice as fast and much quieter. I have the my traveling speed set at 150 ipm but you can't actually cut that fast. My bed can handle a piece a little larger than 24"x48". I guess there is not a limit on the finished size as you can cut your design up into 24x48 sections, cut them out and then piece your sections back together to make whatever size you want. I use Vcarve Pro software and would recommend it to anyone. It is very simple to use and does about anything a person could want as far as routing or carving.

One good thing about building one of your own is that if anything goes wrong with it I can replace the parts myself (which I have not had to do). I hope nobody get the impression I think I know all about cnc because that is far from the truth. I do know a lot more than I did when I started but learn more each time I run the machine. There is a lot more to learn but I can usually do what I want to. I try to keep it simple.

Hey that looks darn nice!!

The bit looked like a large one but it seemed to cut very good details... what kind of bit is it?

How did you make it?
Pics of the system?
What Plan did you follow?

Looks like you're a sign maker...!

Thank you...

Wow, that is fantastic. Thanks for the look see! How about a shot of the whole machine? Very cool!

I'm not a sign maker. I guess you can call me just a piddler. I do a little of a lot of things. This was just a test to see how the machine worked. I just recently retired and thought this CNC would be a good project (and it turned out to be amazing). I really enjoyed it. Learned a lot.

I will try to get some new pictures or videos for you guys.

Me thinks that's quite amazing, especially how it starts one thing, goes to other area then returns to the first. How come it doesn't finish each step before going to the next. Computers, they still amaze me. Did the machine work first try or were there multiple problems and if the latter did you need assistance to solve them?

The bit was a 1/2" 90 degree vbit.

The machine did work the first time but there were a few kinks to work out to make it more precise. I did ask a few questions on a CNC forum and got some very good help. The router travel is more or less figured by the software. A person could change the travel if he wanted to spend the time, but I had just as soon have the CNC make a few extra trips. Quicker for me.

Here is a video of the CNC cutting out a few knobs to use on handmade jigs - http://www.youtube.com/watch?v=djaCFjbopcg. I removed the dust collection so that you could see the action better. These things do make a lot of dust. Also is a couple of pictures of the 5 point and 8 point knobs after they were removed from the blank. Just takes a couple of licks with sandpaper, some paint and add some tee-nuts and they are as good as the ones you buy. There is just so much stuff a fellow can do with one of these machines. They are excellent for making patterns.

Thanks gose........

Now I gotta have one..Looking forward to details on plans gear etc

WOW, that was very cool

Oh and BTW

PLEASE tell me it didn't cost an arm and a leg to make

Was the one straight cutter used for all three operations and am I right in thinking that the cutter didn't go all the way through to prevent the knobs breaking free and hitting the cutter. Sorry to be such a pain, but I'm fascinated.
