K8200 redisign in to cnc

thingiverse

Hi. In this project I would like to redisign Velleman K8200 3d printer in to CNC milling machine. I will try to explain my every step as good as I can. Part 1: https://www.youtube.com/watch?v=2guMUcz4Vms Disassembly printer from all parts and vertical profiles. Print at least 16 corner brackets. Prepare M4 10mm (about 50) and 14mm (about 20) long bolts, washers and nuts. Cut or buy 20x20 aluminium extrusions T-slot in sizes: 2 x 458mm, 2 x 100mm, 4 x 500mm Part 2: https://www.youtube.com/watch?v=jxN05Op_uAI Print 4 of YAxisRailFrame.stl Mount them on our frame on horizontal extrusions (bottom and top one), place printed parts with 12x400mm rail in distance of 110mm from left or right profile (don't forget about bearings, I have only 1 per rail for now). Bolts that I'm using: M5 20mm (4), M5 30mm (8) and some washers and nuts. Part 3: https://www.youtube.com/watch?v=4L1pZ4TGTRw Let's print 4 of XAxisRailFrame.stl. You can use 8 of erlier prepared corner brackets, assembly 4 vertical aluminium extrusions (50cm long). Take our XAxisRailFrame printed models and combine them with 10x450mm rails. Mount everything on front vertical extrusions. Bolts that I'm using: M4 16mm (8) and some washers and nuts and 4 linear bearings. Part 4: https://www.youtube.com/watch?v=WuW093C4IXk Print 1 of YAxisMotorFrame.stl Now tricky part... Take out aluminium extrusion from bottom back part of printer/cnc, take off one Y axis rail holder, put printed part in middle between rail holders and tight screews on place. Now you can add nema17 Y axis motor with trapezoid rod (in my project it's 8x300mm one). Part 5: https://www.youtube.com/watch?v=DEYo9oCoOQM Print 1 of XAxisMotorFrame.stl Take off 3 aluminium extrusions (both from sides and front one), take out top X axis rail, put motor holder on place (in middle, between top and bottom X axis rail, about 10.5mm distance). You will need M3 10mm (4), M4 15mm (4) and some washers and nuts. Trapezoid rod is TR8 (48cm long) with coupler. Part 6: https://youtu.be/JNVt687LsB4 Print 1 of XAxisBearingFrame.stl Do same like in part 5 but put your part on end of X axis. Simply take out top front and top sides extrusions take out top rail, put printed part on place put everything back. Put your bearing (608) inside of plastic part, place your trapezoid rod in motor coupler. Done Wait for next parts/steps :D
