Just wandering, how to make those lines to be close one to another?

I adjust my Z-home much lower, keep your settings, if you can pick your line off the print and unravel it, then you need to lower it

@James_Dobbins Take a look at the picture he posted in the comments. The machine printed 3 layers, 2 solid and one with a percentage of infill and that layer shifted. If you look closely you can see that the 2nd layer also has gaps between the solid infill lines. Because of this the issue is clearly NOT Z offset. It’s clear that it’s improper extrusion rate because it’s happening on the 2nd layer as well. If it was just Z offset then the 2nd layer would look nearly perfect.

Looks like your Y-axis is to thight and the stepper is loosing hughe amount of steps.
If the aspacing of the lines is everywhere, I would adjust your nozzle size, but only if it gets corrected in +/- 0.3mm to your original nozzle size, else the problem is another setting.

If it’s original mk3 you should just call support. That’s part of the price you paid. If it is selfe build you can figure out with the community if it’s a pre assembled clone from overseas, … Your fault

@Lukas_Mathis Did it numerous times. I was able to acheive normal adhesion at nozzle 230°C, bed and 70°C and Z offset -0.560. At default settings print didn’t stick

@Este_ban_S Yep, that is the original MK3 from kit

@Jorgen_Vendorf The print of the bottom part of the enclosure came out ok after I rotated the position on the bed 90° around Z axis

If you have a caliper print 1 layer measure it’s thickness on several points and compare it to your first layer in eoftware

@Xenomorpheus Re-orientation did help and print came out ok. After I tried to print the top part it started to similarly fail regardless of orientation

But the scooping steps layershifting is something I would tell support. The prusa originals are pretty good dieled in normally that shouldn’t happen. Also the first layerheigt is to be calibrated in first setup

@Adam_Steinmark Thanks. This printer is from the kit and it never printed with ABS. All settings - nozzle 0.4, filament 1.75. I wll try to calibrate the extruder according the video

They test all the kit components prior to shipping and I think they may test the hotend with ABS, leaving a little bit behind in the nozzle. You may need to adjust your first layer but that is not your main issue.

@Adam_Steinmark The top part of the enclosure exhibited slightly differen problem

Can you post a pic of the top surface? Hard to see from that pic.

Yeah like I’ve been saying from the start, since you have gaps on every layer the issue is very clearly not due to Z offset of the 1st layer, 1st layer height, or anything else other than extrusion issues. Was this printed before or after calibrating the extruder?

After

That’s odd. What was your new and old steps per mm for the extruder?
