I have a flashforge creator pro 2017 model, and have had since Christmas. It has been a great machine and I couldn’t have been happier until now. Recently a print failed and pla got on my nozzle and now my part a come up and stick to it. I have tried heating it up and using a towel but the towel burns. My main problem, however, is that my y axis squeaks badly, and neither standard oil nor lithium grease fixed it. Help and suggestions would be greatly appreciated!
