Problem with my MK4

Hello, everyone!

Can someone please explain to me why my pritner is doing this nonsense and shifting the print by 4-5 sentiments in some direction?

Could it be the speed because I'm running it at about ~500 print speed?

Or could it be some setting? Though I think I've looked at everything, ugh?

Interestingly, this problem only occurs when I print something with a larger height and it starts to shift after about 6-7 inches?

I use Prusa MK4 and Prusa slicer
PLA but i'm doubly about the brand - its between Fiberlogy or Polymaker
Nozzle 0.4, ~220temp C , Bed temp - ~60temp C

Thank you all!!

RE: Problem with my MK4

Assuming you mean 500mm/sec.  That seems pretty fast. The stock MK4 IS profile for PLA runs the printer at 170mm/sec.

Have your tried slowing it down

Tonight I ran it at normal print speed and it came up correctly, but yeah, it was still all night.

Is it also possible that the infill percentage I filled it with is the problem too, I had it running at 10%?

On the Prusa mini I'm printing parts at 200 print speed and everything is perfect, my MK4 is brand new and when I saw it had the option of 900 and decided to test in the middle 🙂

P.s. I'm newbie and think obviously I'm going to be throwing a lot of scrap until I figure out the capabilities of the printer 😀

Thanks so much for the reply! Be healthy
