Not sure what’s up but I can’t see your pic. I’m fairly new as well but have def been doing lots of homework. 
Are you using Cura? I was able to find some ender 3 tweaked profiles by just searching google. Another helpful tip is to know your printers “Magic Numbers” is.  Basically meaning hour far in mm’s does each “step” (slight turn off the stripper motors). The Ender 3 and the Ender 3 pro use nema 17 stepper motor’s with 16 steps. Therefore, making all your Cura values a multiple of 0.04 well at the very least decrease noise, print time and slice time. I didn’t test any of this but in theory it should increase print quality.  
also, check out “Teaching Tech” channel on YouTube. He does a great job of explaining things without rambling on forever. Me... not so much.  
i think the best advice I got and/or wish I had from the beginning would be:

 your first level is the most important!

- bed leveling... download a calibration file from thingaverse.com specifically for the Ender 3. Learn to use it and do it every time at first until you’re used to it j

- if you’ve touched the bed with your fingers it should be cleaned... use isopropyl alcohol 99% preferably but 91% will do (not 70%) 

-print your first layer at 50%of print speed or  less (maybe 20-30mm/s max) at first, without a fan for first two layers   

Stick with PLA at first, it very forgiving. PETG is similar exhort needs to be about 30-40 degrees hotter. 

print slow (50mm/s)

 

 tweak your slicer settings, take pics/notes and if we all contribute this will turn out to be one badass community capable of “Making” anything! 🙂

@plantagenet

Hello 

 

You may find that the gcode you have generated is applying the temperature change during the print, Have you sliced the file or downloaded the gcode ?
