Here it is a little rough but complete, quite a few changes including the extruded aluminum. I changed the gearing on the x axis about 5 to 1 now, moved the shaft pillow bearings to the outside of the shaft removing all the flex problems I was having before, which caused the timing belts to be too loose. Changed to rigid couplers to avoid any backlash on the x and y axis. I used machined rails for the z bearings for a more snug fit on the bearings removing 95% of the original slop I had with the wood and flat steel setup from before. The gantry is much lighter now causing less strain on the stepper motor. The sign was the first project I tried after the upgrade. I am extremely pleased with the final outcome. The lighthouse is from a picture I used CorelDraw to turn it into line art and create the text, then used CAMBAM to create the gcode and finally plugged the gcode into EMC2 same product and its open source and all together in one package, the operating system and EMC2. You can download it from LinuxCNC.org they have a great group of people that will answer any questions or help resolve any issues you may have with the program and setup, the forums are fantastic. This machine took about 10 months to make as it sits now I did make one project with the original machine and realized there were some major issues causing me to make the upgrades.

Joel,

WOW!

That’s quite a CNC setup… Quite large!!

I see a Bosch Colt router… How does it work in this use? I always thought it would take router of a little more HP.

Where did you get your parts?

What type of computer are using?

Really looks good…

COOL!

Thank you.

I like the extruded aluminum! Nice upgrades!
Is it 80/20?
Is the router mount shop made or purchased?
Any plans for dust collection?

I WANT one!!!!!!!!

Looks like you have interested some folks regarding CNC wood working. I to am interested in the cost of such a setup. If you would care to share. Nice looking device.

Randy that’s exactly what I said last year …ahahahah… yes 80/20 and you can find it on Ebay now, some of the pieces can be a bargain. Make sure to get lots of t-slot nuts and fasteners for the correct size you will need them.
I bought the router mount, I will have to look up where I got it from and I did make a dust collection holder I haven’t installed it yet.
Joe – The colt router is great, Precise bits.com sells special collets for it and they have a nice selection of bits too.
the aluminum is from 80/20.com and the computer is a home built system if you use EMC2 it can be an older system. I have a xp3200 amd cpu, 1 gig of ram, a cheap video card, 80 gig hard drive, and a cdrom drive on this one and it works great, you need one with a parallel port to set up the stepper motor drivers and the breakout boar tho I have heard of USB versions out there.

JoelK,
Thanks for the info.
During my research on www.cnczone.com I actually stumbled upon Lumberjocks.That is when I realized I needed to get my shop setup. Now that my shop is usable, in it’s infancy & not quite efficient, I am yearning for MY very own CNC Router. Your posting just fuels the fire to build it!

As they say; Let the chips fly & fall where they may.

Very nice. I have a machine design for cutting 48×60. I plan on using steppers with 5 to 1 reduction and chain drive for x and y. Z will use a 1-10 acme. Vee wheels and rails for the linear slides, going to use all wood for the first one. I think I will go the Mach3 route. I use Solidworks for most of my designs.

Thanks for sharing.

Hey Joel, nice mods.

Good move changing to the extrusions. They have really come down in price if you shop around.

Using V-rails also seems like a good change with the small travel/length of the Z they don’t cost that much. There is a lot of side pressure as you drag the router through wood, and having tight and strong coupling here is so important.

Good job on the sign. Looks like you must have used pretty small bits to get those sharp corners.

Keep it up, I like it.
Steve

I like the way you’re using one stepper mounted in the middle to drive a torsion shaft, that then transfers the power to both sides of the gantry drive. That should balance things well, should you get any flex in the shaft.

Is your gantry being driven up and down the table by really long timing belts?

Did you blog your build over on CNCZone ?
