Z-Axis_synchronisation system: A8_

thingiverse

Hi 'thingy people'.... I have reviewed as many as possible of the Z synch & anti-wobble systems for any 3D printer on 'thingiverse'. They all looked very good but some for me, were too complicated, so I have adapted, changed, remixed, to a system I feel works for me; I hope you fell the same? The Anti-wobble Top Plates I have adapted from https://www.thingiverse.com/thing:2288314 thanks to 'SmallArtFly' A GT2 Smooth Idler pulley https://www.thingiverse.com/thing:2618509 thanks '3D_PP' The 'synchronisation system' I have designed is specifically for the Anet A8, I am sure that this could be modified for other printers. I do not use a LCD2004 Controller, I use a 12864 LCD Controller so have no use for the button holes.
