Light Corexy for 2020 profile base on Flsun cube 3D printer

thingiverse

First sorry form my English. I decide to rework my Flsun cube for corexy to be able print on whole surface of hotbed. First I was using HEVO parts for 2020 profile from several sources, but there was some problems so I decide to watch for something else. I watch videos from Tech2C and I decide to create something like him just for my requirements. My goals was: - using maximu of original parts from my kit - get corexy to place between two top profiles (need to keep 94mm distance because I already have cute flanks) and don't losse height on Z axis - make it so light as possible - make it flexible for different type of Z sensor - make a simple fanduct to easy change between E3D V6 and Volcano heatblock I designed in for using 10mm elox aluminium rods (like Tech2C) with 45 mm center distance. The aluminium rods is 10 outer and 8 inert diameter so later I put 8mm carbon rod inside it to get it more strong. For X axis i use two IGUS bearings 10x19x55, and for Y axis (with original 8mm steel rods) four IGUS 8x16x25. Pulley is six 20 teeth, two with same diamether without teeth and Timing gear is 16 teeth (100 steps/mm with 16 microseps) Fan for heatsink si 40x40x20 and two radial 40x40x10 for fan duct And i make motor holder and back pulley holder for 2020 profiles For now I just create only fanduct for e3d v6 and holder for LJ18A3-8-Z/BX sensor - I will added other variants later (but they are sipmple parts so everyone cen create his own) Probe offset form extruder is 32 for X and 16 for Y. I print all parts with ABS, 30% infill, 2 perimeter, 0,16mm layer height - some nuts have to be place with soldering station. Almost all screws are 3 mm diameter except that on endstop and radial fanns witch are 2mm and 4mm screws on 2020 profile. Holder for IGUS bearings need be create very accurate, some sharpen can be needed. Only part which i print with support is Y carriage in others you need just find correct position for printing. Part with "left" in name need be printed mirroered for right side. All parts which I uploaded I was printed and test it - working well. Edit: 2019-05-18: I reworked several parts - mainly I rebuilded my printer from bowden to direct BMG dual drive extruder, with volcano hotend and Bltouch sensor and X igus holder devide to two parts for simpler composition. Edit: 2019-09-12 I reworkde (again) fanduct for direct extruder, because bottom part was to thin and too close to hotend which caused deformation of fanduct eaven if it was from ABS (in closed chamber I have 60-65 °C). Second thing - I created parts for my second printer - which is build on tatra frame - X carriage for standard e3d V6 hotend can by used on this printer.
