Having worked on the nitty-gritty details of the technical design for my rapid fabricator since Christmas, I began fabricating components last week. The first pieces to be machined were corner gussets for the 80/20 frame. While similar supports are available through the manufacturer, it was far less expensive to spend a few hours making my own.
The last 2 days have been devoted to machining the linear bearing assemblies for the X-Y-Z axis. Each tracking mechanism required machining on 3 sides, as a result it look much longer to fabricate and maintain a constant level of precision between operations. Again, 80/20 manufactures linear bearings, but at roughly $200 apiece. I chose instead to make my own at less than a tenth of the cost.
