I tried searching about your problem and found out that Punchtec stopped manufacturing 3d printers anymore. Such a shame, I think they also stopped providing support as well for your problem. Anyway I found this link about calibrating Punchtec Ord Bot Hardon Printer. It has a temperature section(just ctrl and find the word temperature) and I thought this might help you with your problem. http://www.k4mg.com/CNC/Ord_Bot_Hadron_Build_Log.htm
