I recently purchased a Used Linatrol HL-90 optical tracer. Im having a problem with it NOT following the pattern, Ive seen where the lights seem to make a little difference so im going to try replacing them first. Would anyone out there have a manual on this unit?? (Ill pay for one) I really dont even know if im controlling it right, it moves back and forth in a straight line, it just wont follow a shape.
Any help would be appreciated.
