To calculate how fast your extruder motor is turning, the layer height, extrusion width, and feedrate are needed inputs.
Also, can you describe clicking? Is the motor stalling? Is the drive gear slipping on the filament?

M201 X3000.00 Y3000.00 Z250.00 E400.00Your previous acceleration for E was very high. The speed was fine. Now your speed is too low 400mm/min is only 6.6mm/s which would be very slow for retraction.
Your extruder max speed should be as fast as your retraction speed. 6000mm/min for 100mm/s retraction max.
The acceleration for E should be fine in the 2000-4000 range. 12000 is crazy high.
