Here is what I have been working on over the past few months.

Homemade and nearing completion finally 8)
That looks like fun. From scratch, or from a kit?
How about some description of the build? Motors? steppers? control? programming?
The bulk of the mechanical parts were destined for the scrap yard. The gantry (y axis) is a piece to an out of date camera system for webbed printng presses.work upgraded to a new system and said I could have the old one if I wanted it. The x axis is two 1.5" acme screws that came out of a scrap sheeter (machine that converts rolls of paper to sheets of paper). The z axis I bought. The electronics are all new. A gecko g540 stepper motor driver, two keling 906 oz nema 34 stepper motors drive the x axis. And the y and z axis are both keling 381 oz nema 23 motors. The power supply is a keling 5020. Z axis came from xzero. I got motor cables from cncrouterparts.com. its a porter cable router. As far as software goes, I have a student version of autocad that is good for two years. Cant beat a $3000 cad program for free ;) I am using vetrics cut2d for my cam software, and mach3 machine control software. One of the acme screws is bent slightly so I will be rebuilding my x axis shortly. After I get that done I will install all the limit/homing switches and ill be makin sawdust fly! Im gettin all excited just thinkin about it ;)

X2, Yeah 8)
Whoa!
That is pretty darn cool! What a great challenge for a computer oriented young fella! Kudos!
None the less, the handiest tools in my wood shop are the two sharp pocketknives I carry ;) ;)

Holy Cow Jake, after this read , I got dizzy and had to lay down. :laugh:
Looking forward to seeing it running.
There are four main types of linear motion used on these machines. Acme thread, ball screws, timing belts, and rack and pinion. This one uses acme on the x axis, timing belt on the y axis, and ball screw on the z axis. I will likley change out the timing belt on the y axis for acme thread in the near future. It works fine for wood but in aluminum you can tell it stretches a little under load. This has definitely been a learning experience. If you fellas decide to build a cnc machine in the future I would be more than happy to give you my .02.
Looks good Jake. That's a tool I could use, to make inlay designs on guitar fretboards.
what's the bed size on that baby? I would really like to build a CNC router someday but I might just end up buying one because I don't know if I will ever have the time to build it, but if I did I think I would make sure it had a 4 by 8 bed, that way I don't have to cut up any sheet goods before I start routing....
This one is 27" x 32" at the moment. I will gain a few inches on the x axis when I rebuild it. A 4x8 machine would take up half my shop. I am actually thinking about building an insulated shed to keep this one in. It would free up room in the shop and it would be easier to heat in the winter if I wanted to do any cool weather cncing. A 4x8 machine would make an awesome panel saw for sure!
Looks mighty impressive! 8) 8) 8)
I'm impressed. Both by the machine and all the knowledge your gaining making it operate. 8) 8) 8)
i've made a joe's hybrid cnc... 4x8 with rack and pinion...
works great, he's got plans for $100 along with access to the forum ( which is the best part )
building cnc's is a slippery slope thou, kinda like owning a sawmill :D

his new evolution build is a solid aluminum build

I saw one in a old hardware store once. :D
After a few operator errors, I finally have something to show you guys. first sign (thats worth showing). It took 6 different kinds of software/programs to get to the final product (not counting internet explorer). F-engrave is actually a pretty powerful program for v-carving once you get the hang of it and it's free 8). My student version of autocad has been extremely handy as well. I don't know what I will do without it when it runs out in a year or so.

That sure looks fine, Jake............. 8)
What's the size and how long did it take?

Me too! LOL LOL
Jake, that is seriously impressive. Do you have the capability to take a small video of the machine in action and post it to YouTube? Would love to see that! Otherwise, keep those pictures of end products coming.
Back to the original question. Any one mention the first aide kit, yet? Seems it is my most go to tool.
very impressive!
The sign is roughly 12"x30" and it took about four hrs. It wouldn't have taken near as long with a higher end software im sure. But im cheap :)
Nice work Jake, all the way around! david
Wow! Nice job, Jake.
I've been thinking about changing my vertical mill to cnc for projects like signs and scrollwork and I did most of the machining work helping a friend build a small version of what you've made. (he did all of the figuring and electronics ;D) I don't know everything about it by far, but know there's a lot of head scratching along the way.
You might look into Master Cam when your AutoCAD runs out. It's basically the same thing. I was using it 10 years ago and loved it. They had a student version then, just a thought.
Anyway, Great work.

Rebuilt the x-axis. She's now 29"x48" and smooth as glass. :)

Nice Job there Jake
We should get to know one another better. I have a Digital Wood Carver CNC now. I did designs and build my first CNC and sold it to a friend when I bought my bigger unit.
I run Vcarve Pro 7.0 software and low it. It is about a $600 package, but well worth it in my opinion. One of the things you can do it cut down big time on you milling time is to create multiple tool paths using various size bits. So in the case of your "Smith" sign, you use a 1/8" diameter bit to do around each of the letters and numbers as the first tool path, stop and change to 1/4" bit to remove materail in some of the other areas, then stop and switch to 1/2 or 3/4" diameter bit to remove material in the larger areas. That will decrease you milling time dramatically
Busy beaver, I think you are the only person I know that has a cnc router other than me. Maybe if one of us posts something the other person likes we could share the gcode? I wont do a lot of signs, maybe one every now and then. I wanted one mainly as a fast, accurate scroll saw for cutting out parts for woodworking. I recently took an autocad class and man is it handy to just draw out a part you want and then take it to the cnc and it does all the work. Once I get done with fine tuning everything I will start doing some projects with it.
Latest cnc project. My mom needed trim for her house. I used the woodmaster for the trim and the cnc for the rosettes.

Some good ingenuity you have put into your cnc. Keep up the good work and photos. bg
Impressed is an understatement, you don't think outside the box, you redesign the box completely.
