Print Problems And Solutions

PROBLEM	SOLUTION
Prints were leaning to one side.	Reattached the Y-axis pulley securely.
Motors were getting very hot.	Adjusted the potentiometers so the motors had just enough power to drive the axis and run the extruder.
Tip temp. read '2511' in Repsnapper.	Reconnected thermocouple more securely.
Extruder motor gear slipping.	Super-glued gear to motor shaft.
The extruder bolt was mis-alinged so the filament was not feeding.	Adjusted the spacing of the extruder bolt with washers.
