When your extruder skips steps it might be related with too high speed or/and length of retraction. Try to increase temp to 215 ~ and modify the retraction size to 2 and retraction speed to half of your value. For me it solved the issue.
Btw. Check your nozzle if it is not jammed. You should be able to push filament using your hand through the nozzle.

Hello. I connected second fan directly to the power source input. I think extruder needs to be cooled all the time, not only while printing.

So i finally made nice print but idk why this problem happend. Can i avoid it next time? Btw thx for reply

Hi. I have a problem with configuring slicer software.
My first print started very nicely but after few minutes ~20 min the extruder pushed not enough filament and i had to stop printing and in addition i noticed one (visible) layer separation. Result: (image i attachment)
After that i started a new print but i wanted to print it out faster so i increased infill speed but it turned out that it

Hello,
I have some questions related to software
1. I am trying to understand this variables:
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 4000, 100 }
and
#define DEFAULT_MAX_FEEDRATE { 200, 200, 2, 20 }
Are they releated with each other?
I am asking only about extrusion params
2. I am using Slic3r and does "Extrusion multiplier" change steps/mm (so modify var DEFAULT_AXIS_STEPS

@Ohmarinus i think it isn't orginal hotend, but i printed nearly whole calibration cube but at the end it peeled off

IRFZ 44N would be good replacement?

I tried a radiator on that mosfet but unfortunatly (i think) i burned it. I am unable to turn off the red light near D8/D9 outputs. So would it be enough to replace the burned mosfet with a new one and use Heatbed Power Module as in the movie ?
I measured resistance with Universal meter ( Firstly i measured inner resistance of meter then measured the heatbed resistance and at the end substracte

Thanks for replys. The mosfet is P55nf06l model. It smoked but there is a possibility it wasn't mosfet but the plastic connector (shown in the photo). I measured my heatbed resistance and it has below 1 ohm. I found that heatbed resistance should be abut 1.4 - 1.6. What should i do to make heatbeed running? If i won't use heatbed can i turn on ramps without replacing the mosfet?

@VDX Would a paper tape be good? I saw on yt this solution

Okay, so the object has peeled off at the end of the printing process so i decided to connect heatbed. But after a while the mosfet started smoking... I think i should have used a radiator for it or fan right?

I leveled table again and started printing. So far it looks pretty good... I will write after print will end

So i have already increased hot end temp to 230 degrees and the results:

I will try to increase the temperature but 220 isnt enough for PLA?

Thanks for replys. The stepper does not skip steps it rotate all the time but the filament is not be able to flow out and new one is being pushed so the extruder damages filament.

Hello,
I created a 3d printer with Marlin software, after setting up Marlin i wanted to print my first object - calibration cube. From the nozzle spils out a little of filament whilst extruder is unable to push filament in correct way and the filament in the extruder comes back. I wasn't able to print even one print. After clearing up the nozzle and trying to push the filament by myself, i think,
