Larken Cobra Stepper motor drivers

Larken Automation is a manufacturer of XYZ positioning tables for the woodworking, signmaking and other industries. Over a 12 year period we have developed a number of motion control products for controlling our xyz tables and now we are pleased to offer them for sale separately.

 Our New Cobra drives operate in 1/8 , 1/4 or 1/2  step mode (1600 ,800 or 200 steps/rev)  These PWM drives use the latest in power mosfet design and are microproccessor controlled. They and are compatible with all step and direction software such as Mach 1/ Mach2 , TurboCNC, Supercam , Lcam and StarCam etc.

Our stepper drives are not sealed in epoxy and the output drivers are replaceable. The Cobra drive is the only drive to have a have a 30 Day warrantee.
