Any tips on keeping the print attached to the board

While I was printing the the print came unattached from the board. this of course messed up the print. Any tips?

 

So far i've used glue stick (Elmer's Purple) and it has worked pretty well with PLA. I'm going to be trying hairspray in the next few days to see how they stack up to one another.

 

I will have to give that a shot. So far I've reduced the speed of the first layer to 1mm/s and 10mm/s on every thing else within the print settings. In filament settings I upped the Extrusion multiplier to 1.9 and the Extruder temp to 190 and Bed temp to 70 on the first layer. Other layers 185 extruder temp and 65 bed temp. Seems like its going smoothly now. Still printing though...fingers crossed.

 

It was working well but it came unattached again and projected got completely borked.

 

I know for me I was constantly having the print eventually come off of the bed. I did two things.

I use a heated bed even for PLA (though I know many say you don't need this I still find that it does help)
I also use hairspray (Aquanet specifically since that seems to hold best from what I've read). I even had my TARDIS print without coming off of the bed and it's fairly tall.

Just remember that if you use hairspray PROTECT THOSE GEARS and RODS! They WILL gum up if you don't do so and that will cause all kinds of other problems. I just use cardboard in front of them to keep the hairspray off of 'em.

 

PLA -- I'm having similar/different problems -- on small parts (Dell Power Cord Button, Robot), it sticks and holds very well (loreal hairspray 40c heated bed initially). It looks like it might fail as it's putting down the perimeter, but when it does the first hatch, it's solid from there (and the hatch holds the perimeter).

OTOH, If I try to print 2 things, one always comes up when it goes from 1 part to the other (evidently the perimeter cooled too much for the bond?) :/

And -- the hairspray has to be fresh/sticky. If you print, then print on a different spot more than 2 hrs later, the hairspray may as well not be there...

 

Chances are you're too high if you're not getting good adhesion. No amount of glue can fix that.​

 

I've had a lot of luck with paraffin wax, I guess the same idea as the glue stick. I also use a brim if it's a big part.

 

I've heard that air conditioning could also affect the print from sticking.

Anyone know what the temp of the room should be?
