3D-Proto CoreXY 3xZ-Axis with single Z-motor

thingiverse

Update, added 2020_end2.stl + 2020_bracket.stl + belt_tensioner_new.stl to stop the 2020 profile where the Z motor is mounted on from twisting and make the tensioner more stable. Conversion of my 3D-Proto CoreXY modification "3Z Axis with 3 motors" to a single motor. This one is based on the dbot 3Z axis mod by Phaedrux : https://www.thingiverse.com/thing:2651649 What you need (you may have already some parts if you did the 3 motor variant first), marked Green/Yellow/Purple in the screenshot: + additional Z M8 rod (three in total) + additional aluminum 2020 profile + two additional short aluminum 2020 profile pieces, one 120mm and one 38mm long I used a spare part from the filament holder as I use a filler instead: https://www.thingiverse.com/thing:3020026 plus the spare from the direct extruder motor mount as I use a Bowden system + one double GT2 gear pulley with twenty teeth, five millimeters (motor) + three GT2 gear pulleys with forty teeth, eight millimeters each (three Z axes) + one GT2 belt length 1250mm (rear Zs) + one GT2 belt length 350mm - 175 teeth (front Z) + six bearings 608 (two for each Z axis) + two GT2 idler pulleys smooth/no teeth, three millimeters wide (belt tensioner) Print two of Bed-Z_10mm.stl (buy some M5 screws at least thirty-five millimeter length and nuts) There are two versions available, one for twelve-millimeter thick wooden panel and one for ten-millimeter. Choose the one according to your wooden plate. + print two of each: Smooth-Z.stl and Smooth-Z_top.stl + print two of twenty by twenty SocketM5.stl + print one of mount_front_single.stl + print two (mirror one) of mount1_rear.stl + print three of block.stl + print three of distance.stl + print three of M8nut.stl + print one of motor-mount.stl + print one of belt_tensioner_new.stl + print one of belt_tensioner_distance.stl + print one of 2020_end.stl + print one of 2020_end2.stl + print one of 2020_bracket.stl + plus some additional sliding blocks and screws to mount everything to the frame Infill seventy percent for Bed-Z___mm.stl, mount_front_single.stl, mount1_rear.stl Infill fifty percent distance.stl Infill thirty percent block.stl, motor-mount.stl, smooth-z.stl, smooth-z_top.stl Infill twenty-five percent for the rest of the parts
