Movement detection circuitry is provided for a moveable component of an apparatus having an encoder member having a plurality of spaced regions to cause a response by a first detector and a second detector on the moveable component. First and second detection signal detection signals are received respectively from the first detector and second detector by processing circuitry of the movement detection circuitry. At least one of the first detection signal and the second detection signal is sampled when the first detector and second detector move relative to the encoder member. An error due to any impairment to one the spaced regions of the encoder member is based upon a comparison between the samples from the two detectors. A movement characteristic of the moveable component is determined by the processing circuitry from at least one of the first detector samples and the second detector samples.
Movement detection circuitry for a moveable component of an apparatus, the apparatus comprising an encoder strip having a plurality of spaced regions to cause a response by a first detector and a second detector on the moveable component, the movement detection circuitry comprising:
Machine readable instructions to detect movement of a moveable component of a three-dimensional, 3D, printer having an encoder member with a plurality of spaced regions to cause a response by a first sensor and a second sensor, the machine readable instructions being provided on a machine readable medium and when executed to cause position detection circuitry, to:
A method of detecting movement of a moveable component having an encoder member with a plurality of spaced regions to cause a response by a first detector and a second detector, the method comprising:
