What the thread found

• Random motor twitching and vibration can occur on older Bartech systems even when the hand unit is not being touched
• Fresh batteries in the receiver and motor can temporarily resolve twitching symptoms
• The potentiometer inside the M-One motor is the component that wears out and causes intermittent failure leading to random vibration and attempted position locking
• The potentiometer will eventually wear out regardless of manufacturing quality, causing gradual intermittent failures rather than complete failure
• Replacing the potentiometer is the permanent solution to motor twitching and vibration problems
• Motor service and potentiometer replacement may be available at no charge if the unit is relatively new and shipping costs are covered

Depends on

• Applies specifically to older 8-bit Bartech systems with M-One motors
• Fresh battery fix appears temporary rather than permanent
• The claim about free replacement is based on individual experience and characterized as uncertain
• No technical specifications provided about what constitutes potentiometer wear or failure mechanisms
