I’m trying to print PETG at 240 °C nozzle / 70 °C bed on my Ender-3 V3 KE (latest official firmware too).l also changed my start code so it’d be set to those temps and I’ve already done a full PID autotune. The printer heats up right at first, but as soon as the print starts it snaps back to 180/60 or sometimes 200/60, no matter what I set. I have also changed filament settings too. I’m stumped on what to do since this is my first 3d printer ever.
Hello !
Are you using CrealityPrint as slicer ?
In that case, can you check in Materials if that was saved (as first layer and other layers)
In the Printer profile, can you check the G-code start?
