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 °C for PETG. after the first few layers, the heated bed set point changes to 0 °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.
If you start a print there is an "Adjust" button, that will take you to a screen where there is an option "Economic". It that is left on it will turn off the bed heater during the print.
No, this is not common behavior, and yes this can cause your prints to warp or detach from the build plate.
The question is whether you instructed this (by accident) or not (e.g. it can be a result from slicing or some economy mode of the printer). This should be clear if you look into the G-code file that you print. The typical commands that concern bed heating are M140 and M190.
Please note that this a generic answer to find bed heating operation in your G-code file. Other answers, e.g this one and this one hint to a specific ability of the printer that shuts off the heating of the bed when it is working in an economic mode. Note that this is printer specific.
The heat bed turns off because economy mode is set to on by default, change this in the adjustment menu.
I do have the CR 10S Pro as well and for me it does the same but only because it's a setting in the slicer I enabled. Make sure you check the slicer settings to make sure it is not a setting which is turning it off.
Personally I do let it cool down after 10 layers since it does save energy, and I've not seen any negative effects because of it when printing PLA. Have not yet tried PETG or ABS on this printer.
I have a new CR10 max.
I can't find any adjustments for the bed temperature settings other than the basic ones in the Creality slicer. I'm not sure if the latest software has got this facility.
That is not normal behavior for the heated beds. I don't have that exact model, but when I print the heated bed will stay to whatever temp was set in the slicer program. Unless you override it manually on the printer itself during the print. I would check slicer settings ensuring temp doesn't change after it's first layers.
