I purchased a 101hero which arrived today. I put it together with no parts clearly broken but the hot end only heats to 89 degrees! I am unsure what to do or if it is a rookie mistake. I left it for about 10 mins on 89 degrees and it normally took about 30 secs for 1 degree. Also with no movement whatsoever it started saying 33 percent finished at 89 degrees! What do I do?
