    OK, so I already did a PID autotune for my target temp of 230° C. on my hottend, but no matter how slow I go I cannot stop my hottend from dipping way below my specified temperature. For some reason, it is only an issue at these higher temperatures, as printing PLA at 210° is rock solid stable. Any ideas?
    I have got a Printrbot Simple Metal with an e3d Lite6

    Thanks :)

    Is there a fan blowing on the heater block?

    Did you PID tune yet?

    Yes, the heater block fan is active, and I already ran PID auto-tune at the wanted temp (230° C)

    There should not be a fan blowing on the heater block, only on the heatsink.

    If you have a fan blowing on the heater block, you need to properly duct/reposition it so that it does not blow on the heater block, but instead on the print that is desired to be cooled.

    You might want to post a picture of your setup. It says more then a thousand words according to some ;)

    So, it was in fact that I had an un-shrouded fan blowing on my heater block. Once I turned it off, temps were stable, so I printed a new one that will fit .

    Thanks!
