Shaft Encoder Signal Essay
To do so, the Print Engine is fitted with an encoder input (Shaft Encoder ES: subpixel encoder) that will be connected to a system which copies the displacement of the object. Whatever the resolution, this system will produce a pulse every micrometer. Impika proposes a solution consisting of a rotary encoder and of an interpolator to be directly connected to the ES input. This system can be assembled on a rotating axis or on a coding wheel rotating on a band or a belt. Composition of the encoding system: The system consists of the following parts: A rotary encoder with a 1-m long built-in cable. Reference: …show more content…
The Interpolation value should be set accordingly.

6.2 How to determine the take-off diameter?
If the encoder is assembled on a shaft driving a belt on which the item to be printed is placed, the take-off diameter equals the diameter of the shaft plus twice the thickness of the belt. The theoretical value has to be adjusted in the printing controller to consider the equipment features. The final control can be done through the dedicated printing test pattern control.
Item to be
