I have a problem which is that it prints the pieces badly, for example in the xyz cube it does not print the letters (here a photo), or this cubone skull also failed in the end and the horns were missing.
Another rare mistake is that when printing has rare errors, an example, I want to print a mini drone frame and when it is round it prints a weird line or does not follow the guide that easyprint 3d shows me

Hi, You can calibrate your extruder,
Then check the flow rate in the section settings;
For slicing software, you can use Repetier Host or Cura.
Printing speed reference range is 30-60mm / s;
If the model itself has a large inclination, support may need to be added.

Hi,

it seems to me you have problem with printer setings
Maybe you have a layer thickness too large. For starters and even later, 0.2mm is just right.
did you set the correct printbed height?
watch this video

also you have the first layer too thick.
if you have a nozzle of 0.4 the first layer of 0.3 is enough.

watch this video too.

I don't think that print has anything whit support. first layer is bad.
for start and calibrate printer, use models without support like xyz cube or 3dbenchy

and
if I may mention
this is a great site for troubleshooting

I was following the videos and in cura when printing goes well but I have layers shift, How can I solve that?

Hi, If the layer moves,
You can check:
1. Adjust the tightness of the belt properly;
2. Whether the bearings and pulleys are issued with cards and the cards are lubricated with lubricant;
3. Reduce the printing speed appropriately;
4. The driving board voltage is in the range of 0.8-1.2V.

Do as William wrote you.

Just a question.
Does the layer shift look like this?

I already reduced the speed and the same thing happens, this is how the layer shift looks
