Hi BerniApple. If your NEMA17 looses steps while extruding during a print, are there any visible marks in your print?
You may try to increase your nozzle temperature or crank up the extruder motor driver power. Some people use a DRV8825 stepper driver instead of the 4988, because it's able to deliver more power to the motor.
