Building my 2nd CNC first, I hope. I have been researching for over a year, read a thousand threads and articles, and am hopefully building my 'second machine' for my first. There is still a ton to learn and that process will probably never stop. Of this I am certain, I will be in new territory for a while. For over 40 years I have been building things, doing hydraulics, pneumatics, and electronics builds and troubleshooting along with a lot of woodworking but have never used or built a CNC machine. This is going to be fun!!

The machine is a new model by Nate at Fine Line Automation. It's a 'pro' series he calls Saturn and it is very heavy. Shipping weight was 525 lbs. for this 2'x4' model. Take away the OxBox and pallet and it's probably still 475 lbs. The frame is welded and stress relieved steel, powder coated Pantone 305. It has THK style linear bearings, rack and pinion drive, and the components are anodized black 6061 aluminum. I have a 3 Kw water cooled spindle and NEMA 34 stepper motors ready to mount. I'll be using the Hitachi WJ200-022SF VFD to drive the spindle. The actual cutting area is 28”x52” with 10” Z travel.

The first order of business, now that it's here, was clearing out enough space in our shop for two CNC machines (our shop is the attached two-car garage). It has to set in one place while I build the stand where it will actually reside, so space for two in an already crowded shop. I'll be building a frame with 2x4's and maybe a couple of 2x6's. Then I need about 5 large friends to help me carry the CNC over to the stand.

Picked up from FedEx and barely fit on a friend's trailer -

Next step will be a trip to Lowe's for 2x4's and then make some sawdust.

Hope you enjoy the ride with me!

Fusion 360 for CAD/CAM along with CorelDRAW X8 and leaning heavily toward Mach 4 for the controller. I may also use FreeCAD and SketchUp to some extent.

I don't know a lot yet regarding CNC's , but that gantry looks rock solid heavy duty to me :)
I have a whole lot to learn but I have a long history with 'old arn' and I like some heft to my equipment. My preference is to have equipment I can lean on without it moving.

And you are correct about the gantry; it weighs 125 lbs. by itself. I have the option of filling the frame with sand if I need additional weight or if there are any harmonics or resonance issues. Adding additional weight isn't something I'll need to do, if I were to take a guess... :no:

Looks like you picked a good starting point. I still have the plans for a home built machine by Solsilva somewhere in a cabinet drawer. 2x4's, skate bearings & such. Nothing like your pictures.

When you build the table for it, you might want to leave an opening in the top that lines up with one of the gaps in the frame. Sooner or later you'll want to do some vertical/angled end cutting and that hole will let you clamp parts standing up for tenons/dovetails/box joints on their ends.

Looks like a great system but when I first glanced at the first photo with what appears to be a paver in the background I was beginning to wonder just what you were in for. :grin:

Yep, I was showing Sandy just a few minutes ago how that would work and why I'll leave a portion open for doing vertical pieces. Good call, 4D!!

Now that would be a truly serious machine if I need to 'up' the foundation first, right!! LOL!

Finished the stand today. I know I'm thorough but this took me about 20 hours to build and I have no idea if that's slow or fast or about average. It's actually fast for me and I managed to do it in two sessions - 8 hours yesterday and 12 today.

All the pieces that will contact the CNC frame are jointed to ensure they're flat and straight and each hole was drilled with 1/8" for threads, 3/16" for the barrel, countersunk for the head, and securely tightened, so about 4 operations for each of the hundred or so fasteners. Each joint is square and tight and then the entire stand was sanded. I may come back later and put some Shellac on it but not today.

A friend is coming over tomorrow and bringing his engine hoist so we can lift the frame onto the stand. More later!!

Wow heavy duty looking stand David . I'm thinking maybe some more studs on the bottom and some plywood covering to act as a place to store stuff underneith

Thanks, Rick! More studs for bracing or double up like I did on the top?

I left it open so I could go back and put shelves or drawers in but figured I would wait to see just how I use the CNC before committing to a storage type.

Looks beefy enough. Might plan for a cross brace running 90 degrees from the first center one once you have the CNC weight on it. Just in case there is a little racking in the long direction under that weight.

No I was thinking of more bracing /studs on the bottom level by the floor for shelving . But forgot about 4D's idea of an open bed design on one end to clamp verticals pieces for tenons etc.
I guess a guy could still do some of it

We managed to get the CNC frame lifted over the table saw extension and on to the stand. The stand worked perfectly, so that's a good feeling. Nothing creaked or moved and it is dead level with the additional nearly 500 lbs. of weight just as it was without the frame weighing it down.

My friend Adam, also a good woodworker, brought his engine hoist over and we managed to maneuver the CNC over the obstacles and set onto the stand and only had to move my air compressor to make room. That's not a bad feat given how tight this was.

Here's a good shot of the CNC in our shop. There's some clutter from moving things around to make room for this but I'll get that organized and cleaned up soon. You can see the spindle, steppers, and other components on the bench so hopefully I'll get a chance to start mounting those over the next few days.
