Prints not sticking to bed as starts going “crazy”

looks like the bed is to far from the nozzle so yes you want to raise the bed up a little bit. You can also scuff the build tak with the rough green side of a kitchen sponge to get some adhesion, but I think its mainly in the offset. Also heat can effect PLA and cause it to warp, make sure your not printing to hot. Typically 190-200 range is normal for PLA. sometimes cooler but start in that range

 

keep us posted!

 

It looks decent. You can likely manually level out the high spots (where its making "ruts"). Ideally when your first layer goes down its a nice even "layer" all the way around (like the top layers of prints) but that will work if its not warping up. At least you can print and get use to the machine. Dont be afraid to adjust the numbers or play with the level on the bed to get it "perfect". If you go into utilities, memory? (cant recall exactly) then eeprom, home offest you'll see your numbers. (for example mine is -12.74, everyones is different) just remember that number and if you liked those numbers better than what you change it to, type them back in). can I ask what the dull spot in the center of the buildtak is? (bed)

 

oh gotya! I'd suggest once you get a bit of printing under your belt that you replace the buildtak. Robo does sell them in the shop but you can buy direct from build tak and cut to size (just wont say Robo on the front of it). Your call, but replacing it when damaged isn't a bad thing (wait until you are getting great results off the machine though, or until adhesion drives you crazy and you need new). You can always go to buildtaks website and look up their process for sanding them down to make them "like new" again.

 

if your in the states and look on amazon you'll find 3 packs that are prime and decent priced.
