Issue with 3D printer making super thin layers Recently I've been having trouble printing properly on my Creality Ender-3 printer. I ran a pretty long print (approx. 15 hours) that turned out really well. I then started printing an attachment for the original print and saw that it was printing layers that were extremely thin.  

I first scraped off the excess filament left on the extruder nozzle. Then, I heated up the bed and rubbed off the layer with alcohol. I tried printing it again but it still didn't print right.

Thin layer


Weird thing


From the images above, you can tell it's noticeably hard to see the layer, which shows just how thin it is.  

I sliced the model in Ultimaker Cura. I set the layer height to 0.15&nbsp;mm. I've printed models before with this height but the layer wasn't transparent.  

What should I do to fix this issue?
You need to level you bed.  Thin prints happen when the extruder is too low and is printing too close to the bed.



Download the following test codes from this address:

1) The first code is the most important you will want to run moves the extruder to five points on your board - Front Left and Right, Back Left and Right, and Center.  Using a folded piece of paper - I use a business card - drag the paper under extruder of each of the four corners.  You want to make sure you get a bit of drag when pulling out the paper/card.  If you feel have enough of a gap that you can run put the paper/card under the extruder and that you feel a bit of tug when pulling it out.  It runs the middle last - if you are having issue with the drag, adjust all four corners slowly until it is right.

2) The second runs the extruder in a square pattern on your board.  You simply want to run your finger of the print - if it sticks to the bed, you are good - if it doesn't, adjust your corners up and keep testing.
