    I've got an early Robo3D's and getting an extruder temp reading of 357.5* upon start up.

    Is there a way to know if the problem is the hot end or the thermistor? (I have one of the early Kickstarter printers with the ceramic hot end). I've removed the hot end and cleaned and reconnected all the wires, same error message.

    If it is the hot end can anyone recommend a good replacement? I've found some online, but they are about $100. At that price I think I'd just replace the whole printer with an Ender 3.

    Thank you.

    You can't get R1 hot ends on eBay for about $28 each.

    Thanks (although I'm guessing you mean 'can').

    How likely is it that it's not the hot end but the thermistor or board that is the problem?

    Is a new printer, like an Ender 3, going to be able to do things the Robo with a new hot end can't? I was looking at the prints from the Ender and was really impressed, but don't know how much is to do with hardware, software, or set up etc.

    My old R1+ is a trusty old machine. Much less temperamental than any of my Creality printers.
    I have always gotten excellent prints from Robby (Robo's name).
