I am having problems getting my prints to adhere to my buildtak. At first it wasn't even coming close to sticking and after playing around with the setting some (turned up the first layer heat and increased the first layer extrusion) I got it to stick, but I can't keep it adhered to the plate after 400 or so layers. I am not using the heated plate since that didn't seem to keep things stuck when I was first starting, but is that what I am missing? I have been making sure to keep it clean with my scraper, but should I wipe it down with alcohol? I am tempted to go back to painters tape and a glue stick since it never failed once I learned to use it. Does anyone have a suggestion?

Use the heated bed, trust me it will make all the difference. Run it at 60* if you want parts to really stick and 50* for everything else. Then just keep it clean and make sure your first layer height is correct, not too high or low. It also will change based on the filament you use, so make sure you are using quality filament and no cheap stuff from ebay.
Once I started using a heated bed with my buildtak, I haven't had a failed print due to unadhesion. In fact, I haven't had a single part warp even the slightest no matter what I threw at it. And this is with probably a combined total of almost 1000 hours of printing on 2 different machines

Thanks, I'll try this tonight. It sounds like the hotter the material gets the more adhesion I'll get. Is that the trend?

Pretty much yep! Until you hit a certain point, then it won't make a difference or it will start to actually reduce adhesion, but that isn't until probably around 90 degrees for PLA.

You were completely right. I set my bed to 60C first and subsequent layers and the board mounting bracket was tough to get off. Even the perimeters that it lays down to prime the extruder were hard to get off without a scraper. Thanks for the quick feedback!

I've found that 60 degrees makes it stick too well so I usually use around 50 now! |

Any user recommendations for ABS? I prefer to use only ABS hoping I can simplify my life by learning all about one compound than jumping around with several compounds. I've been heating my bed to 70* and getting good adhesion. The squeeze of the first layer to the bed is most important.

If you can avoid any drafts, especially if you are printing large objects, thats when ABS is a huge pain to print. Some people increase the bed temp to 100c but you usage is always different.
