I have an ender 3 and i wanted to get a smooth first layer so I put on a glass bed and I’m using a glue stick to make the prints stick to the bed better and it’s not sticking, what else can I try to do to make the prints stick, I’m using hatchbox pla and I’m printing at 210 C nozzle and 60 C bed plate and it is all level because I leveled it 3 times thinking that it was the problem, any advice would be appreciated, thanks!

Hi, You can produce stickers on hot beds.

Hi,
I've no idea if this will help - But it won't cost much to try it...
I only print in PETG - so not exactly the same - but I use blue masking tape...
The cheap stuff you get from a DIY store.
I have a roll that's 50mm wide, so 4 strips laid from left to right looking at the print bed, one behind the other laid with no gaps and no overlap covers most of what I require.
I use nothing on the tape. No sprays, glues or anything else.
I've found the filament sticks pretty well - And the tape will generally last several prints before I replace it - again, very simple and cheap to do...
The bottom surface of my prints look smooth enough.
I leave the bed and nozzle at temperature for a few minutes before printing just to make sure everything's up to temperature and settled down.
I generally set the print to draw a skirt around the component to be printed at a distance of 8mm, three circuits.
I find that this primes the head and gets the filament flowing before actually starting the print.
I find the height of the first layer is very important.
I have a 4mm nozzle and usually set my layer at 0.3mm with subsequent layers at 0.2mm.
I tend to print my 1st layer at no more than 60% the speed of subsequent layers.
I hope some of this helps, as naturally I always watch my first layer print - If it looks good, then I can do other things and leave the printer.
If the 1st layer looks poor or has gaps, then there's a much higher probability of a failed print.
