Default 2nd Build (first) - CNC Router

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 -


OxBox container removed and setting on the pallet until I get the stand built -


A few close-ups –






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 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...

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.
