Hey SandervG,
I don't remeber it giving me the option to pick the firmwear, this is the first time I used it and loaded cura 15.04.5. I do not have a unicontroler on it so it runs right from the pc. On the initial setup it asked which UM you had, I chose "Original", then it has check boxes for any upgrades like the heat bed, I did not pick the heat bed so it would not register, it then told me to hit the " Upgrade Firmwear but did not say what version nor did it give me the option too. Is there a location on the web to allow you to chose what firmwear to use?
The max temp issue comes into play on the heat bed, would the top of my print head have anything to do with the bed? Again I am a new user and inherited this machine that has troubles so I am systematically trying to eliminate one issue at at time.
Thanks for you patience with me as press forward to hopefully some fun and fantastic printing
