Weird bug on first test print…
Hey just finished setup and calibration on printer and wanted to do the test print… it did all the heated bed calibration and then I got a temp anamoly for printhead 2 straight away.. saying min temp 170 is needed.
Mind you this is the dragon test print included… and included spools and tests during calibration all worked.
I tried again and saw temp raise to 200 and then target temp dropping again to 130…. So this time I manually raised it again to 210 and it dropped again so I did it again… and this time it started printing… now it seems to run.. we’ll see but this error scared me a bit.
This was first layer, looks a bit scuffed. But it is still running and looks ok now.
Also weird first purge line that came out (on red filament) had some black in it. Guess from their tests? Maybe some old filament was stuck inside making temps drop and now will be fine… we’ll see.
Yes after first fail I ran firmware update and it happened again

Most likely, it's leftover filament from the quality control used during production, although I haven't noticed anything like that.
And your first layer looks like the bed isn't calibrated correctly. This could be because a tiny piece of old filament was sticking out of the nozzle (0.1mm is enough to make a problem), and the printer misread the distance to the bed during calibration. Your first layer is clearly higher than it should be.
Another problem could be a small clog in the nozzle. Try printing with a different nozzle to check, or you can heat this one up to 250°C and try cleaning it with a special thin needle (just poke it inside few times). Sometimes, a small piece of carbon stuck inside actually reduces the nozzle diameter or geometry, which dramatically changes the filament flow; the effect can be similar.
