Creality CR-10S Pro 3D printer heated bed turns off after first few layers: normal? When I run prints on my Creality CR-10S Pro 3D printer (using Ultimaker Cura as slicer), I set the heated bed to around 70&nbsp;&deg;C for PETG. after the first few layers, the heated bed set point changes to 0&nbsp;&deg;C. 

Is it normal for a 3D printer to turn the heated bed off during a print, or is this a problem?

I have had some parts warping, and wonder if this is a potential cause.
Cr-10 S Pro has an eco mode make sure it's not turned on because this will turn your bed off after the first few layers have printed.
