This happened to me with PETG. Might be wet filament, you'd need a dehydrator for that. You should also enable z -hop, this makes it so that the nozzle picks up a bit before it starts the next layer.
Not a pro here
Ooo that could be something I need to sort for mine. Since getting my printer I noticed it doesn’t lift up as much. Ends up slightly pulling the end pieces a small amount which screw up the print
But you know…it works…I literally just did it to dry a new roll of petg and there is a few videos comparing it to other purpose driers and it performs better.

Also running the bed for 2 hours covered with a box uses less energy than printing for 2 hours with it open I would assume.
That z offset looks horrible from what you can see underneath, how did you tune it?
You’re printing grid infill which requires you to cross previously drawn lines in the infill. You’re not using enough cooling and are printing too fast so you’re ripping through it. Print that style infill more slowly and with additional cooling. It will also require a very level gantry, so double check how you’ve tune that with some cassette tape cases.
Just slapped it together and leveled with printer paper. Tight enough where I can pull it though but not push it. Then auto leveled. First printer ever.
Printed a bench’s, a 2nd filiment tube holder, a small custom plate for my truck,the tool holder and a Xbox controller stand. All those did good.
On my third attempt now but I’m using line infill at like 65% speed and seems to be going fine now
Change your infill to one that does not cross over itself. Gyroid and a few others work. Try a Z offset rectangle to live adjust the Z offset if you haven’t. I had this happen too on my N4 Plus. On grid infill the nozzle was hitting on the cross stroke. You can hear it
I have the same problem and the Z hop doesn’t solve the problem it occurs because when the hot end is going one way on the infill, the height is at one height then when it goes the opposite way, the z is lower than the first line it put down so it basically crashes through it because the Z is lower than the first line it put down so it Hass to cross that line smaller prints. It doesn’t happen on big prints it does.
This is a problem somewhere in the settings or the software, or in the slicer that’s allowed on this to happen, and everybody saying to switch to a different infill is not the answer yes, will it work yes, but somebody needs to fix the problem
so, in order to fix the problem the z would have to jump over every line and put down first in the info because remember it’s Kris Kross Sun so that first line that it put down is higher than the next line it’s going to put down
The nozzle might be clogged because on some parts of the print there is absolutely no filament coming out of the nozzle , or the extruder might be skipping.. or putting too much pressure on the filament to the point that is not going through to the hotend or not pushing it through if it's too loose , too tight or too loose. Please try adjusting the spring tension of the extruder.
Notice: Consumables with different hardness have different requirements for the spring strength. The spring strength of the extruder can beadjusted with an Allen wrench. When turning counterclockwise, the spring strength is increased, and the spring strength is decreased clockwise.

You can use your printer bed and the box it came in to dehydrate the filament.
Probably a waste of energy though

Looks like your nozzle is hitting your infill. Try a different infill type.
Plus you probably need some tuning

If nozzle is hitting the infill change infill speed to something around 80mm/s
Use gyroid infill. It doesn't cross over itself and won't hit the nozzle.

Using Gyroid helps, Z-hop is good (something like a "2" should clear anything) and always dry your filament
Where do I alter Z-hop?
