Ender 3 pro how to stop lifting prints and clogging.

Question

I have been gifted an Ender 3 Pro for my art department. I&rsquo;m completely new to 3D printing so having to learn from scratch, so please bear with me. 
 I tried one print and had some success but the first layer was a little rough. But every print since then hasn&rsquo;t stuck to the plate. It will outline initially but then it starts pulling up. I read about levelling the bed so I have done this, then I also tried to upping the temperature of the first layer to see if it helped stick. But no joy. I seem to get an outline which lifts and then when it goes to print it clogs/ lifts and never settles. I&rsquo;ve tried increasing/ decreasing the gap. But it doesn&rsquo;t seem to help. Any advice would be really appreciated as I&rsquo;m just stuck and frustrated! Thank you!

Try increasing the bed temperature and slowing down the print speed.

From the image it looks as if you nozzle is not close enough to the bed - the lines should be squished a little bit, and they need to touch each other. Try a 80x80mm square, just 0.2mm thick - when printing it you can easily check that there are no gaps between the lines. Ideally after peeling of the print its a solid sheet and the lines do not disconnect from each other. Maybe look at https://all3dp.com/2/ender-3-pro-z-offset/ for methods to adjust the Z offset.

1. Level your print bed 
 2. Dry out your filament, and put it in a dehydrator. 
 3. Clean your print bed, use high proof alcohol, a gentle scourer. 
 4. Heat your bed, at least 60degC, make sure your filament temperature is also appropriate for the filament, 200degC is typically good for PLA. 
 5. Consider turning off fan assist, or turning on fan assist. Try with either and see how well it does. 
 6. Try using a 'raft' to help for adhering prints to the bed.

I had issues like that due to a broken extruder arm. Maybe check that yours is ok, or replace with a metal one (they&rsquo;re about $15cad iirc). I have more detailed info and pics here on e14, maybe try searching for Ender and my name. I&rsquo;m away from my desk, so I&rsquo;m a bit limited for now.
