Prusa Z axis, so many problems yet one simple solution !

Note: This has worked perfectly for more than a year and is still valid. BUT, I wanted to go further and get rid of all the crappy linear bearings and poor leadscrew nuts. Done, I even managed to get rid of the vertical smooth rods, the lead screws can do the job (although TR10 would be more rigid, TR8 are acceptable) see here: https://www.thingiverse.com/thing:2594693 WARNING: Don't be misled by the negative comments found here. This WORKS ! Unfortunately some people either misunderstand or simply lack the proper knowledge to understand, others are just expressing their anger for my critics of their poor, flawed "things". Just check what these people published and demonstrated. Some even created accounts, nothing published, just to spit their hatred. Amusing :) PS: Beware, some are crooks, as they tried to call for funding or sell their wares I shot down ! See the first posts below for such piece of human garbage ! ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
