BCN3D+ X-end modification

thingiverse

I am making an improvement to the BCN3D+ that just occurred to me while trying to adjust the tension on the X-axis belt:\r\n\r\nProblem:\r\nThe X-axis belt applies a pressure that causes rotation of the X-end-idler and the X-end-motor. I also found it really tough to tighten the X belt because there is hardly any space to grab the pulley to make force (and the more force you make, the more you rotate the final parts).\r\n\r\nSolution:\r\nThis made me think of adding a third, threaded 8mm rod, beyond the belt, between the X-end-idler and the X-end-motor, which allows for tightening these and tensioning the belt (and thus countering its pressure). To achieve this I have modified the design of the X-end-idler and the X-end-motor, allowing to add said 8mm threaded rod. This I have protected with heat shrink tubing (so as not to damage the extruder cables in case they rub against it), and I have re-routed these cables, as well as those of the X motor (so they don't get caught when Z is at maximum).
