Rotary Delta Printer

myminifactory

Rotary Delta Printer, inspired by the Icepick Delta Project this is my latest Version of a Rotary Delta. Most of the Parts are printed. You need a workspace of 300x300mm to be able to print all Parts. I used PETG as material and an infill-ratio of 50% with 4 Perimeters and 4 Top & Bottom Layers. You should be familiar in using manuel placed supports. I oriented the STL files as I printed them. I recommend to alaign your Printer as good as possible in X/Y/Z orientation because this will have an effect to the accuracy of the machine.   You will need following Parts for the assambly: -> Bearing 608ZZ  18x -> Bearing 696ZZ  18x -> Shaft, Diameter 6mm, length 52mm    6x -> Shaft, Diameter 8mm, length 82mm    3x -> Shaft, Diameter 8mm, lenght 145mm   3x -> Hexagonal Spacers, lenght 20mm, M4 -> Carbon Rod, Diameter 30mm, Inner Diameter 28mm, lenght 173mm, 3 pieces -> Carbon Rod, Diameter 8mm, lenght 375mm, 6 pieces -> 11mm Steel Balls with M4 Threads -> Opto Endstops -> Super-Glue -> Nema 17 -> HTD 3M 9mm Pulley, 40 teeth  3x -> HTD 3M 9mm Pulley, 20 teeth 3x -> HTD 3M 9mm Pulley, 14 teeth 3x -> HTD 3M 9mm Belts, -> HTD 3M closed belt with 174 mm 58 teeth, 3x -> Aluminium-Shaft, Diameter 28mm, Lenght 122mm, M5 Threads on Bottom & Top   Some Values for FW-Setup: Base-Radius: 80mm Effector-Radius: 35mm Arm-Lenght: 190mm Rod-Lenght: 394mm Angle when homed: about 46.50°  (When you measure the arm-angle on bottom of the Carbon-Rod you have to substract 7.9° to get the correct angle) Stepps per deg with x32 Micro-Stepping and 1.8° Stepper: 391     Some videos of progress: https://www.youtube.com/user/Egris
