Please Excuse my english
Some tips:
Check filament flow rate is lower than the nozzle can handle . I have e3e Revo Micro and this page has useful:

Try to put the spool over bearings to minimize the pull the spool makes to the sensor
Check the sensor wheel is clean and if don´t cleanit by removing the plastic stuck in it
Check the extruder is not loosing steps
Check the extruder e-steps is correctly calibrated (if you send 100mm to extrude (G1 E100, you measure exactly 100mm )
