Last year I created an unusual proof of concept of a CoreXY type mechanism intended for use with a 3D printer. Although the initial tests were quite positive, I had concerns about the weight of the overall implementation and was very unsatisfied with my initial designs for the Z stage of the printer. I recycled the parts into the K03 delta printer and let the idea simmer for a while, saving up some extra money for research and...

After many hours of working through the wiring for the K03.2 revised Delta prototype, I now have a running machine again! I am still in the process of testing it out, tweaking the software and tuning the print quality but it’s working very promising already. More work needs to be done to properly finish the top structure of the printer, it needs a filament spool holder desperately. For testing purposes the filament has been sitting...

After much printing of parts, lots of drilling and tedious routing of wiring the base of the machine now looks like the above photo. It now has it’s AC/DC power supply integrated and mounted internally and there is wiring in place for all of the electronics. The next steps are to actually connect that wiring to it’s intended connectors and also to finish designing and printing the new top corner pieces of the frame. This second...

After the success of the 3.1 prototype I took a break for a few months to let the concept stew. Several people have expressed interest in building one but the actual assembly process was quite complicated and over-engineered. Quite frankly, I actually didn’t put in all of the intended bolts because it was too tricky. There were other issues with the design such as the overall weight of moving mechanism which I have some ideas to...

Meet the K03 first working prototype. It’s not as pretty as it could be due to all the blue tape at the top, but it works and it works well! At this point I wouldn’t recommend anyone attempting to build this machine, despite my success with it. It has a few drawbacks which could be particularly daunting for anyone new to 3D printing. In particular – the roller mechanisms are slightly too heavy for the holding weight of...
