My 3D printer project Rostock like. Check it on http://youtu.be/Zh0OgjKmn-M 22 dec 2014 Added effector cap for E3D hotend mount. Filament feeder: http://www.thingiverse.com/thing:282969 10/04/2015 added 'effector_j-head_top' 10/10/2015 added new 'diagonal_rod_fix' 10/12/2015 added new direct (on effectors top) extruder: http://www.thingiverse.com/thing:1067150 SolidWorks 2013: https://grabcad.com/library/deltabot-3d-printer-1Main parts I used: 2pcs IKEA LANTLIV Plant movers 3pcs Nema23 motors (Nema17 is good too) 3pcs Nema23 mounting L-brackets (I have not usual mounts but the bottom parts that I publish is for common mounts from China manufacturers) 6pcs GT2 20teeth pulleys (upper 3pcs could be printed) 5 meters GT2 timing belts 6pcs 800mm long linear shafts 10mm 6pcs LM10 linear ball bushings 12pcs SK10 shaft support blocks 6pcs SA6T/K ball rod ends 6pcs SA6T/K ball rod ends with left-hand thread 6pcs F605ZZ (F605) flange bearings (5x14x5mm) 2 meters 6x8mm aluminium tube (230mm x 6pcs)Is better to check the symmetry of holes in plant movers before assembly shafts mounting parts. Also I used the centering device (look photo) to mount the shaft support blocks. It is the flat aluminium plate with two rigidly fixed 10mm pins.My Marlin-deltabot settings: DELTA_SEGMENTS_PER_SECOND 200 DELTA_DIAGONAL_ROD 260.0 // mm DELTA_SMOOTH_ROD_OFFSET 172.86 // mm DELTA_EFFECTOR_OFFSET 45.79 // mm DELTA_CARRIAGE_OFFSET 18.82 // mm
