Updates include: -belt tensioning with adjusting screws -traxxas 5347 ball joint ready parts -place for end stops -Legs -easily adjustable end stops (max end) -belt locking mechanism with M3 screws All above "things" are included on printed parts, original parts are modified by me, some over 95%, there are not much original design left. Still every part is fully compatible with original design. More images and everything can be seen: http://www.rc-hemmot.com/keskustelu/viewtopic.php?f=11&t=6 (hope this link works) 5.1.2015 minor tweak on p_motor part, more space for heat bed screw 13.1.2015 Extra legs, five is more stable than 3 and .stl files for idler wheels, up and down. New improved belt tensioning with 2 tension screws for more accurate belt tensioning. New belt tensioning part is not yet tested, so I keep old one until new is approved. 17.1.2015 Removed single screw belt tightening part, new one works just like it should and removes possible bad alignment completely. My printer is advancing again, I had issue with bed leveling probe placement, but all is good again and finally I can really start to dial it in. 20.1.2015 And no no no NO, there is way too much play with carriages, rotating other end up and other down. Instead throwing everything to the bin, I did redraw again carriages, now with dual linear bearings and this feels like problem is sorted out. New file p_carriage_dual.stl makes everything better and firm, no more extra play and no more jerky moves at certain speeds. 23.1.2015 This is... actually was the problem http://youtu.be/2ccPAmUY2SQ weird no one have actually mentioned this, at least I cant remember seen topic for loose carriages. Over here on Thingiverse is only one dual carriage present, well I don't have this problem anymore. Still not printing, but it moves, again... :P ...And again..... :P getting close now :) http://youtu.be/pYqdsYe_wbQ Integrated bed leveling: http://www.thingiverse.com/thing:650746 Frame files: http://www.thingiverse.com/thing:660904 24.1.2015 And my Rostock prints!
