About this 3D model

Update: 17/03/15 ------------- ### Added y_motor_holder_rack.stl as the .scad file requires the original wallace scad config file. --------- ### Added y bearing retainers. * y_bearing_retainers_4x.stl *this is a set of 4 retainers nicely arranged* * y_bearing_retainers.stl *one single retainer* * y_bearing_retainer_stopswitch.stl *y bearing retainer with an assembly for a stopswitch* I personally do not use this. This is here just for principle of completeness. --------------------------------------- Description: ---------------------------------- This is a compilation of the original Wallace (http://www.thingiverse.com/thing:14208 ; be sure to check out whosawwhatsis's github for the current files at https://github.com/whosawhatsis/RepRap-Wallace) and the Wallace++ M8 Edition (http://www.thingiverse.com/thing:45207) plus a Y axis modification made by Komb (http://www.thingiverse.com/thing:37787) The base is from the original Wallace. The x_end_* parts are from the Wallace++ M8. I modified the diameters for the bearings to be a bit wider. I did not manage to get the bearings in with sponnets configuration. The Y axis mod replaces the belt with a rack & pinion system for more stability and rigidity. This was all printed on a QU-BD TwoUp with PLA. I use the Merlin Hotend on the Gregs Wade Extruder Reloaded without cooling. The Merlin hotend is designed as a passive cooled hotend and the first print test confirmed it's passive cooling abilities. However the PLA needs proper cooling to achieve a good print quality. The 3rd picture shows a 0.5mm wide wall-only cube. Left is 0.3mm layer height, right is 0.1mm @ 60mm/s (Perimeter). This was the very first print I did on the Wallace after I had calibrated all the axis and the extruder.
