*Gear drive motors and drivers and power supply available at https://www.omcstepperonline.com/?tr...

A note from the builder of this robot: "I used all 10 tooth pulleys on the motors in axis 1,2,3,5. Axis 4 and 6 are directly attached to the motor shafts. So the steps required to travel the default amount of travel may differ for other Moveo arm builders. I used tb6560 stepper drivers at 1/16 excitation"
