Freshly built mk3s and stock gcode. What am I doing wrong?

Prints are coming out relatively good, but very stringy. I just plugged in the provided card and didn't touch any settings 215/60

💡 First thing you could do is reduce the size of your attachments.

I think the nozzle is too high. Try Live adjust Z in calibration. https://help.prusa3d.com/article/ZhBlGFD9Ah-live-adjust-z

Sorry for my poor English. I try to do my best.

I didn't get much success after printing the Benchy on my MK3S kit. I resliced the models from the Prusa site and they came out far better.

Dunno maybe the gcode was for the 2.5 or Mk3? Either way, try reslice them with the MK3S settings from Slic3r Prusa Edition

You must go up the PINDA

PINDA height is okay - but First Layer Cal needs to be adjusted. The brim should be a connected set of rings, fused together forming a solid rim around the part.

Stringing is a different issue. The sample gcode files should work well with the Mk3 and Mk3S using the included gray PLA filament. Before starting a print, make sure the nozzle is clean, that no plastic is stuck to the tip. Also good to check the nozzle is flowing freely by extruding several centimeters of filament manually. If the filament wants to curl and ball up, nozzle needs more cleaning. Once the nozzle is clean, there's less chance it collects stray extrusion to string. Also, room temperatures can affect prints. If your room is especially cool or especially warm, print temps may need adjustment. Using the TUNE function, raise or lower the nozzle temp 5c at a time to see if it has any effect on stringing. Usually this will help to compensate for conditions.

Also - make sure the print fan is running ... if off, PLA can string worse.
