Basic delta robot - NEMA 17 steppers driven from Raspberry Pi
thingiverse
A simple, mostly educational model of delta robot driven by 3 stepper motors.I use 3 NEMA17-48 motors, DRV8825 stepper drivers and Raspberry Pi to drive it directly from Ondsel/FreeCAD. Software, source FCStd files and more info: https://github.com/kwahoo2/freecad-motor-driverArms can be used on motor shafts without flats, M3 bolts are required to squeeze them."Cones" are used to set initial position of the arms.Top plate holes spacing is compatible with Stemfie3D construction set.Ondsel releases https://github.com/Ondsel-Development/FreeCAD/releases
