Martin They still may be a type of step and direction drive card, or they may just be the amplifiers. Choppers are a type of drive for Steppers. How much info do you have on the cards. If we could get more information we could give more help. Do you know the specs on your power supply. What about the winding resistance on your motors. What is the physical size of the motors. Any information along these lines would help although somebody on this list may already more familiar with "Chop2 drive cards" and Centroid controller. EMC2 can be configured to drive Servo's of various types and Steppers the trick is determining which electronic hardware components to plug in between the computer and the motor. Then again how old is old.
