![]() ![]() It also simplifies the plotting algorithm as each 'motor' can have a different delay.G-code co-ordinates are sent to the plotter via a bluetooth link. This is a distinct advantage if your motors have short leads. ![]() 1Using two arduinos simplifies construction as there is no limit (other than the limits imposed by I2C) as to how far the motors may be spaced. A sloping line is obtained if the motors rotate at different speeds. A vertical line is obtained if both motors rotate at the same speed for the same period of time. This instructable describes an experimental 'hanging plotter' that uses two 'Arduino Uno R3' microcontrollers each of which is connected to a stepping motor. ![]()
