 Checking for twisting of the linear encoder scale.
 Checking for a space between the encoder sensor and linear encoder scale.
 Checking for contact of the encoder sensor with linear encoder scale.
 Checking for the presence of damage on the linear encoder scale.
 Check the slack of setscrew.
 If the motor encoder value is larger than the linear encoder value, loosen the
tension of linear encoder scale since it may be too strong.
 If the motor encoder value is less than the linear encoder value, strengthen the
tension of linear encoder scale since it may be too loose.
 Check the slack of setscrew.
