Nozzle Temp Is Set To 0 When Printing

My CR-10 V3 printer always sets the nozzle temperature to zero when printing a G-Code file. I've used Creality Slicer and Cura. The file looks like it has 180 for nozzle temp.

It's got to be something easy, but I'm unable to figure it out.

The printer is stock out of the box. I have attached the G-Code file.

@bmayzer check the screen info, for the nozzle temp, what is it? if you preheat PLA, does the nozzle temp rise up? 

better provide a pic of the screen.

@eli-liu

Thanks for the help.

Set machine to CR-10 S5. I loaded the Benchy boat, set the nozzle temp to 180 and bed temp to 55. Did a Save G-Code to memory card.

Loaded Benchy G-Code in CR-10 V3. Nozzle temp is 0, bed is 55. I can change the nozzle temp after loading Benchy and it will heat to the set temp.

Preheating PLA sets temp to 185, bed to 45. Nozzle does heat up to 185, bed to 45.

I don't know how to attach more than one file so I attached the CR-10 V3 screen picture but not the Slicer picture.. The first few lines of the G-Code is below.

Mine was a simple problem. When you run a G-Code, the printer is given the nozzle and bed temperature. Then it starts to heat up the bed, after the bed is up to temp the printer starts heating the nozzle.

 

I was starting the printing process and seeing the bed temp target at the correct value, the nozzle temp at zero. If I had waited until the bed temp goal was reached, the nozzle temp target would have been set to the value in the G-Code and would have started heating.

 

Bottom line - wait until the bed is up to temp, then the nozzle will heat, at least in my case.

@bmayzer This is the normal process for the printer. The mainboard has to read the commands bylines. Heating bed and nozzle are separate code lines, that is why the nozzle starts to heat until the bed temp is reached. 

If you don't wanna wait for the heating, you can either preheat PLA before printing or manually input the nozzle temp value when it is 0.

Hi I recently purchased eSun PLA 1.75 filament for my Creality CR6 SE however, I never had good results. The print is always stringing and defective. In short, I never had good prints with this filament. In this case, I would like to know what is the best filament for my printer? Thank you very much.
