What are the specifications of the encoder being used?
ANY manufacturer should be up front and honest about these parts and specifications. The parts should all be quality and match the manufacturer’s advertised claims of quality and accuracy. If ANY manufacturer(s) fail to answer any of these questions fully, acts secretive (says “top secret”), or just fails to answer the questions. My advice is that manufacturer has some thing to hide and any customer not getting good answers to these questions should look else where for a digital or digital hybrid faceting machine.

Generally I would say that at least potentially a true digital faceting machine, followed by a quality hybrid digital, and then an analog faceting machine, are the most accurate in that order. The accuracy of course depends on the quality of parts used. True digital faceting machines are potentially the most accurate, it depends on the manufactur
