hello people, i have a autolynx 100 and it has developed a fault. i have the complete manual including cicuit diagrams . the fault is that the feed motor is not running at control speed. it is pulsing.ie it accelorates up to speed then slows down and on an on pulsing . i have checked the feed back from the coil on the back of the motor and seems ok. it seems to be the triggerig system is not working fast enough to produce smooth control. any help would be appreciated. has any one out there got a motor control board for one of these machines.HELP.
