Thank you all for the input! Nozzle was clear, original receipt was provided, and she sits level on the ground. Can't wait to get home this evening and take her for a test drive!
I have the opportunity to purchase a slightly used (50 prints) Ultimaker 2 for $1850, seller assures me it's in good condition. It was purchased 2 months ago. I'm going to go look at it later today and maybe pick it up. Are there any less obvious things I should be looking for? Version/Generation issues? Wear unique to the machine? etc? Can't wait to get printing!
