Prints not sticking to bed with a new 3v2

I feel like I've done the piece of paper bed leveling about 50 times now. Over and over I get the same result. I pre-heat the bed/nozzle and wait for it to be fully up to temperature. I get all the corners and center leveled, I start the print and when it does the initial thing down the side it is already not sticking. When it starts the skirting it immediately isn't sticking.

I've wiped down the bed with alcohol as well.

The only prints that have worked so far (not perfectly, but mostly worked) were the cat and dog that came on the SD card. I've followed online instructions for using Cura for slicing so I think I'm doing everything right. What should I be looking at or doing differently?

I assembled my first ever printer (3v2 too) this afternoon and had the same problem. In my case is was a matter of having the bed too low, even though I leveled my bed countless times with the paper trick. Try turning all bed knobs 1/8th of a full circle looser and check whether the nozzle wont scrape across the bed. Then try printing. Repeat until the filament sticks well.

Disclaimer: double-check the nozzle doesn't touch anywhere on the bed before printing every time you loosen the knobs - don't ruin your glass please.

If you are using a glass bed pull it off and scrub the fuck out of it with dawn dish washing liquid. Rinse completely and let air dry.

I feel your pain, had same issue on mine starting out. Nearly gave up until I just tried painter’s tape on my bed. Less hassle than anything. Sticks great and does not require constant cleaning. Worst I have to do is baby step down .1 mm at start of print to really squish the first layer down from time to time. I suggest trying that if all else fails.

Thanks for the tip!

I ended up increasing the bed and nozzle temperatures and that helped a lot. I also ended up lowering the z limit switch slightly, since one of the knobs for adjusting bed height was really loose and I think that helped a lot too.
