We all have or had some similar problems, here are some hints to get over it before you are unhappy 😉

1. Be really sure if your **bed is not upside down**.- Check it, again, now!
2. Double check your **wiring of the modules** , now!
3. Make sure the wire of the heated **bed doesn´t hit anything**!
4. After turning on, **Firmware Update** , NOW!- There are many serious problems at the first firmware!
5. Check if your **extrusion rating** is right, look at the forum or www!
6. **Begin printing small** , easy things will get you easier happy.
7. Problems with the first layer?- **Check level gcode** , search for it in the forum!
