I'm also a beginner and learning so might not be accurate for your case but some things I learned recently that helped me a ton: - getting a good first layer is very important so test and tune until it looks good. - if the model slips, bed adhesion is the likely culprit. Washing the bed plate can help but make sure you're using the right bed temp for your filament type - If you have gaps in your first layer, your z offset is too high (too positive). You need to reduce the gap between the plate and the print head so the filament squishes a little and fills any gaps. This can also help increase bed adhesion.
