Thank you for the reply! I highly appreciate your help...
I checked my Current E - it was set to 1250 mA. I bumped it up to 1300 mA and believe the skipping frequency has reduced a bit, but is not eliminated. Would setting this higher be beneficial?
I do not know how many hours the machine has as I am not the original owner. The previous owner used it extensively.
Thank you for your time and help. It is comforting to know that should the skipping persist, it is not damaging the motor.

Welcome in here!
I've seen your first posting about this (when I looked at your profile), so I'll know you have an Ultimaker 2..
You also have tried to variate the nozzle temperature without any success, right?
Well, there is a few thing to check here, first go into maintenance menu, then select advanced setting, roll down the menu and find motion setting. At the very end you'll find a setting; Current E (the electrical current to feed the feeder motor with), check that this current is set to minimum 1200 mA (milli Ampere).
What you have is a stepper that is skipping, -as we say. This is happening if the energy (the torque) the stepper motor can do, is set to low and the filament inside the bowden tube is compressed and act as a spring and pushes back the stepper motor when it come to it's limit. So the skip back is not normal, -but it is a kind of protection and your feeder motor would not suffer..
Next question to ask is, how many printing hour does your printer have?
Ok. Let us know how this go before next step.
