Hi all. I have acquired the power supply and two control boards for some powerful stepper motors. The controllers are rated at 120V.12A.!! Theyare made by a German firm called Stogra (Who also seem to use the name Zebotronics).Unfortunately the source of these bits threw the motors in the skip,along with the precision 1" lead screws.Does anyone know of a (cheap) source of these motors, some of which have a built-in encoder? There is an English agent in the North of England but given the price of small steppers I haven't dared to ask how much a new motor might be.
