A bit of history to give my post a little more content. I've always been captivated by CNC and started building an MDF machine a couple years back. I was trying to do it on the cheap and it was originally a skate bearing and mdf monstrosity. I went as far as ordering v-bearings but humidity starting getting to my mdf and basically decided to scrap it and salvage what I could. I have some pretty nice THK ballscrews but other than that it was pretty much a wash.
Last summer I dove into a reprap and it is a great primer to get your feet wet in the world of CNC, but it just fuelled my bug.
I've been following the development of the CRP and after a few months of collecting parts my build has begun. First off, I have to give my recommendations to Ahren. He is a great guy to deal with and the parts he provided exceeded my expectations. I couldn't reasonably build parts of this quality and for what he charges for a kit, it's a no brainer for me.
UPS originally lost a batch of my extrusion (I live in Canada and UPS makes me want to lose my mind every time I have to deal with them). So a claim was filed and a new batch was ordered. I had extrusion for another project lumped into it as well. I got it dropped off at work and the receiver guy had called me up to inform me my order was here. I went out and found two orders. UPS threw out the claim and I ended up buying the second order at an extremely discounted rate vs. shipping it back.
I was collecting parts for two machines at this point but luckily a friend of mine came up to visit last weekend and we started tinkering with my machine. Long story short, I sent him home with a nissan sentra filled with extrusion and parts. He's hoping to turn his into a plasma table. So I sort have TWO concurrent 4896 builds happening.
Going back, getting the table together I think I would have laid out the two 1545 rails and measure out and squared up one side of the corner brackets as that's basically what I ended up doing. Then bolt all the crossmembers in and tighten the opposing brackets. Ratchet straps were also my friend in this.
After I got it all bolted together my table would seem to be out of square about 1/32". Is that tolerable or should I be trying to work that out? I am out of level just a touch though so that might be where I'm getting that from.
I also need to take a step back and build a proper table to go underneath this thing as I don't know how much my little sawhorses will take. It's just too exciting, I can't stop. I also ended up with two extra chunks of 3060 so they are bolted to the top of my sawhorses. Nicest dang sawhorses I ever had.
I don't know how long this is going to take to get together as the one with boobs that lives in my house says I have to finish "the baby room" cause she's in "her last trimester". Apparently our priorities aren't quite in line.
