I had a friend drop off a Carvewright CNC router today. He bought it a few years ago and he's about as non techie as they come. In fact, he's content with his flip phone because he doesn't text and he refuses to get on the internet. Anyway, he bought it and found out quickly that he was in over his head. I downloaded the new Windows 10 version of the software and haven't really had the time to play with it. Anyone have any experience with one? If so, enlighten me.
The more you cut, the more chips and dust you generate. When a router is used, there is often a fan in the router that blows down while it is cutting. That breeze will blow chips away from the cut with enough force to keep them from being sucked up by a brush perimeter shop vac collector in place. I honestly haven't found a way to get "perfect" collection of the debris generated while the CNC is cutting. If I know I'll have to suck/sweep some up after a cut, then it is less damage to my ears to NOT use a shop vac and simply let the chips fly. The "other" thing most jobs produce is very fine dust that wafts through the air and will end up on everything in the shop. To keep this out of my lungs I mount a filtered air cleaner right above the CNC beds in our furniture design shop. When the wood being cut is making more dust than chips I also wear a dust mask. 4D
Some of you have seen this documentation of our CNC build but many may not have been a part of this experience. It would take more time than I have available to edit this for specific time sensitive comments (i.e. ...tomorrow I'll get..., or ...I'm waiting on this part to arrive..., etc.) so it will be easier to just post this verbatim from my notes. Sandy and I took delivery of the frame about a year ago, July 8, 2016, so this story begins from that point. It will be a long post covering the entire build that took several months. Due not only to the breadth and detail of the story but also the somewhat limited time I have to dedicate to this it may take a couple of weeks to get everything posted. So let's dive in!! David +++++++++++++++++++++++++++++++++++++++++++++++ July 8, 2016 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! David
