I’m sure nothing folks haven’t seen a hundred times before, but here’s my build so far.
[attachment file=89433]
Because I don’t know what I’m doing with it yet, I’m going for a relatively tall build. I might want to try an extruder, or I may want to try some liquid coolant/lubricant in which case I will want to put a tray for catching the splatter underneath.
My thought is that if I want higher stiffness and reduced Z range, I can add stiffeners to the legs and insert a raised work surface, or I could put holes in the table below the feet and lower the legs through the table without having to disassemble much.
I think I went too cheap on the 608 bearings and they do not run smooth. In my first test with a single linear rail, I used some bearings I already had, and apparently they were nicer than the bulk pack I got from Amazon. I am most likely going to tear everything down and replace the bearings but there are other things I can move forward with in the mean time.
The deck is basically a table with no legs. It is simply particle board supported by some 1x4 boards on edge. I’ve used this design (with legs) for work benches in the past and it’s surprisingly stiff for very low cost.
