QuoteFrans@FranceFirst thing I notice is the space between the lines in the rim. looks like under extruding and would explain that the brim doesn't help as much as it could.
No, it happens time to time, mostly when after I calibrate Z, it autohomes right before start printing and miss just a little bit, which is enough to make first layer's tracks not as wide as they should be. And of course, whe

Sorry for being away for so long.
Performed a lot of trials and adjustments.
For now, printing with following conditions:
Environment: hermetic box from acrylic glass;
Adhesion: PVA/water 1/10 mix, brim 10-20 loops;
Heatbed: 110 C (for first 3 layers), than 70 C;
Hotend: 245 C.
Hermetic box not actually helping much: it keeps temperature inside around 30 C.
But I'm still using it because it keep

Actually, it works fine again. So, problem was in sudden shortcut where thermistor contacts hotend.
Now fixed with dielectric varnish.
Thanks for your advises.
Though, I still want to know how to check thermistor, or any other socket for internal shortcuts (just in case))

To ensure no shorting, get some silicone RTVDon't know, where to get that stuff in my country, but I hope I'd protected it well enough with dielectric varnish now.
So far printing, keeping my fingers crossed).

Did you inspect the thermistor socket on the controller for intermittent shortcuts?Not yet. What am I supposed to do to check it?

I've got Createc3d Prusa I3 with E3D Full Metal hotend.
Not sure, what thermistors were shipped with it and don't know, how to check it.
But, according to settings in Marlin firmware, it is 5 (ATC Semitec 104GT-2) for hotend and 1 (EPCOS 100k) for heatbed.
It was working fine for about 1,5 year now.
I'm printing with ABS.
My settings are:
hotend temp: 245 C
heatbed temp: 110 C for first 3 layers,

Have you tried adding a brim around the print
I'll try and write about results.
And what about blowing on the model?
I see almost everyone uses fan to blow somewhere down to the nozzle area.
I've tried, and it seemed to dramatically increase delamination between layers...
should i use it?

I'm printing on Prusa mendel i3, 3mm ABS, 230-240 degrees hotend, PVA mix for adhesion.
I'm facing delamination on models with big square.
First i've tried 100 degrees heatbed (default setting).
As it stickes bad, i`ve started to play around with bed temperature.
The PVA mix seemed to be the best adhesion soluton for me
(the only way to pick off the model - is to heat the bed back to something
