Itopie Experiment Upgrade [PROJECT STOP IN STATE]

thingiverse

02/08/2017 The project is stopped in its current state and will not be modified further since I have gotten rid of the machine. 03/04/2017 UPDATE! I changed the length of the lm8uu homes on the Xend just like on the Prusa i3, by the way, speaking of it, I slightly extended the Xend to the right so that I can install a screw and an M3 bolt in order to properly constrain the smooth rods of the X axis on the Z axes. 18/12/2016 UPDATE! I modified the lower thrust bearings of the trapezoidal screws, allowing for better access to the motor screws. 01/09/2016 !!! BETA VERSION!!! UNTESTED IMPROVEMENTS!!! The idea here is to permanently integrate M8 diameter trapezoidal screws into the iTopie. I therefore drew inspiration from what was done on Lulzbot machines for Z axis guidance, and I modified and modeled some parts while trying to keep the original design as much as possible. You will need trapezoidal screws with a minimum length of 350mm, yes I know it's usually around 300 or 400, but that's what happens when you don't develop the machine from scratch, but it can be done. I also planned to block the axes in their printed parts using M3 bolts without heads, just like they do at Lulzbot, but as far as I remember, the diameter of the locking screw is larger. I modified the Xend so that the lm8uu are no longer held by simple pressure from the printed part but are trapped in a cage that will be locked with M3 bolts and screws. Regarding the length of the screws to use, you can look at what suits you best until I test it myself and determine any necessary changes after your potential feedback.
