I DID order the vxb bearings, two pair, for X/Y.
I emailed Hiwin and they say the ends are machined to BP Series 1 without power feed dimensions, so that'll be just like the acme screws in the machine now.
I think aluminum for the brackets. 1" or so. If you build up a box with say 3/8 x 1 1/2 or 2, bolted up, that'd stiffen it a lot. I'm thinking polycarbonate covers so I can watch the pulley's and belts whirr around!!
I ordered servos and power supply stuff from Keling today, and some other electronic stuff from CNC4PC. This should keep me entertained designing stuff, installing the ball screws which shipped today from only 200 miles from my house, and working on electronics and drive boxes. I'm going to hold on Z until I get X/Y going, which will probably take me months!! |
