Printrbot Simple Metal 1403 Extended Legs

thingiverse

I recently finished upgrading my Printrbot Simple Metal with the Matrix Precision X,Y, and Z upgrade kit, which included extended legs to provide greater stability during long Z-axis travel. Unfortunately, these extended legs were not printing correctly for me despite using the official model provided by Matrix Precision on their website: http://www.matrix-precision.com/pages/downloads . After some investigation, I realized that the issue might be related to Cura's slicing parameters rather than any inaccuracies in the design itself, as all other measurements were spot on. As a solution, I decided to create my own custom model based on Matrix Precision's original design. I made a few adjustments, including reducing the height and adding a 0.5mm cant at the base of each foot to account for the bending that occurs in the legs over time. In addition, I must admit that I have always found legs or feet on printer designs to be ineffective when placed on glass surfaces, which is why I often add Sugru to the base of the feet for added stability. Even with this fix, my printer still exhibited noticeable jittering. To resolve this issue once and for all, I now place Sugru at the base of each foot. I successfully printed the new design using 0.2mm layer thickness, 20% infill (although I would recommend increasing the infill to achieve better stability), and a speed of 70mm/s. The material used was plain-ol-black-1.75-pla, which yielded satisfactory results. The settings for printing are as follows: Layer thickness: 0.2mm Infill density: 20% Print speed: 70mm/s Material: plain-ol-black-1.75-pla
