    so i had a print fail it coated the hotend with plastic,
    i heated up the hotend at lunch to 300 to get the glob to loosen so i could slowly take it off..
    tried to salvage the hot end no go.
    ended up ripping out the pt100.
    got everything back so i could try to print replacement parts and such with my second hotend.
    since i have a dual i plugged and extra pt100 into the connector so it could read both temps for both hotends.
    im getting a max temp error. but everything is hooked back up right.

    any ideas of why it wont get out of max temp error even though i have the pt100 in place and such.

    thankyou in advance,
    Ryan M.

    Can you give me a better idea of your current set-up? Under what conditions is the PT-100 failing?

    im getting max temp error and everything is reading Zeros.
    I have hooked up new PT100 just to see if that helps.
    still no dice.

    What printer do you have? Do you use a separate amplification board, or is integrated into your main board?
