When I looked to find a machine that could not only complete a task one day, but could be retooled for something new the next week. I've built many 3D printers, lathes and other machines so I knew most of the tried (cartesian, corexy, delta) designs wouldn't give me what I wanted. The SCARA class machines seemed like they could fit the bill and I think I was right.
Having used many machines, from hobby built 3d printers, to mini mills and lathes and large CNC machining centers I had a good feel for the performance I was looking for. I wasn't looking to try and build the cheapest machine out there, but I was out to build a highly reliable and accurate machine for the least cost possible. Fortunate enough to have the right tools I opted for all steel construction with a welded frame.
While the machine worked quite well, I was left wanting. As created it could only complete a single task. In addition I wasn't very pleased with the reach, payload, resolution and ease of programming achieved by the lite arm.
We have also released the full Source Files
Mass Production of 200 Coasters
This is one of my favorite drawings we did in our TSP Art series

TGIF, I sure could use a drink. How about an ice cold beer
Here it is doing some motion tests
Source files coming soon in future updates as I get them in sharable order. You can see an assortment of projects we've created here. In spelling order 2.5D milling, 3D Contour milling, Welding, 3D Printing, Hot Wire Foam Cutting, Pen Plotting, Glass Etching, Laser Engraving, PCB Milling and PCB Assembly and Plasma Cutting.
I attended the Hackaday Unconference in Chicago, it was a lot of fun.
Thank you Mike for sharing the letter our robot wrote for the coordinators. Hackaday post about the unconference
