CoreXY Prototype Assembly

CoreXY Prototype Assembly

  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...

K03 – Up and Running

K03 – Up and Running

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...

K03.2 Delta Base and Start of Wiring

K03.2 Delta Base and Start of Wiring

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...

Start of New K03.2 Delta 3D Printer Prototype

Start of New K03.2 Delta 3D Printer Prototype

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...

K03.1 – Delta Prototype First Build

K03.1 – Delta Prototype First Build

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...

Prusa i2 Current Build – 2014

Prusa i2 Current Build – 2014

I may get around to documenting this printer further, however much has been already written on the Internet about the Prusa Mendel i2 Printer so I will focus on how I changed the original design. Extruder For the extruder, I have done away with the traditional gearing system and put a hobbed pulley directly onto the shaft of a NEMA17 stepper motor. A spring loaded system presses a 308ZZ bearing against the filament and provides pressure...
