 To tell RepRapFirmware that your printer is Polar and to define its parameters, put command '''M669 K7 Raaa:bbb Hccc Fnnn Annn''' in your sys/config.g file on the on-board SD card. The parameters are: '''Knnn''' Geometry class, 7 = Polar
'''Knnn''' Geometry class, 7 = Polar '''Raaa:bbb''' Minimum and maximum radius in mm. If only one value it given it will be used as the maximum radius, and the minimum radius will be assumed to be zero.
'''Raaa:bbb''' Minimum and maximum radius in mm. If only one value it given it will be used as the maximum radius, and the minimum radius will be assumed to be zero. '''Hnnn''' Radius in mm at which the homing switch is triggered during a homing move. If this parameter is not present, the homing switch is assumed to trigger at the minimum radius.
'''Hnnn''' Radius in mm at which the homing switch is triggered during a homing move. If this parameter is not present, the homing switch is assumed to trigger at the minimum radius. '''Fnnn''' Maximum turntable speed in degrees per second
'''Fnnn''' Maximum turntable speed in degrees per second '''Annn''' Maximum turntable acceleration in degrees per second per second
