I've been printing with the newly flashed and haven't had a problem since. the "I" is the Integral, in Proportional, Integral, Derivative AKA PID
What I did was run the pid autotune a few times then heated up the hotend to 230 with fan on at 80%, used the menu, Control/ temp/ menu changed the "I" I raised up and or lowered by increments of 0.10 while looking at the temp read out till I landed on the setting that kept the temp stable. Don't forget to save those settings to your EEPROM before you turn off the printer.
