All you need to know to have a good performance since the first layer
Warping, print not sticking to the bed... There are many first layer issues that can affect the final quality of your print. In this article, we will focus on the adhesion issues that can cause your print to have a poor quality, or even losing it.

This article will go a bit more in-depth on how to fix this issue.
What are the first layer issues and why those happen
Mainly, there are two types of first layer issues: Warping and wrong Z calibration, sometimes warping can be a sign of a wrong Z axis calibration. You can spot this when you see the first layer is not stuck enough on the printing surface or the print curls up after some time.
This can happen mostly when the distance between the nozzle and the build plate is too high, but there are many points that can also make this happen, from the BCN3D Cura configuration itself to hardware issues with the hotbed. We will take a look at all the points that cause this in the next point.
How to fix it
As said above, there are a lot of points to look at when you are having trouble in getting your first layer just right, we will list them here. Try to follow them in order, if a point doesn't fix your issue, go to the next one until you solve it.
1: Calibrate the Z height of both heads
Make sure the nozzle distance is right by calibrating the Z height, go to Utilities/Calibration/Printer Calibration, and follow the steps that the screen shows. These articles will help you get it in the sweet spot:
2: Choose the right adhesive
Every material is different and has different properties, this also translates to adhesive compatibility. For example, Magigoo Original works great for PLA and ABS, but it's not so good at sticking on PA. Check out each filament tutorial to find the right adhesive for each filament.
3: Make sure the printing surface is hot enough
Some materials will need a certain temperature in order to stick on the printing surface. Check that the printing surface is at that temperature. As a tip, let the printing surface heat up about 5 minutes before printing to ensure the build plate has an even temperature. If the print still pops off from the build plate, try raising the temperature in 5ºC steps until the print sticks properly. If the bed temperature is too high, you'll notice a printing issue called "elephant's foot", try to find the sweet spot for the bed temperature.
Note: The default settings for our BCN3D filaments have been tailored for good quality and reliable results, and are fully tested by our laboratory.
If you see that the printing surface is not hot enough, doesn't heat up or suddenly stops heating mid-print, check out this article:
4. Some materials need a warm build volume
ABS, PA, PP, and PPGF30 have a high contraction ratio, this makes them likely to warp up if they are cooled unevenly. This generates the need of an enclosed build volume. Try preheating the bed for 30 minutes before printing with those materials to ensure a warm environment and prevent warping.
