<p>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.  </p>

<p>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.</p>

<p>Thin layer<br>

<p>Weird thing<br>

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

<p>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.  </p>

<p>What should I do to fix this issue?</p>

Note that you need to check the level an bed-to-nozzle distance once every few prints.

You should feel some drag when you pull it between nozzle and bed.</p>\n\n<p>Other solutions that also work include the redefinition of the Z=0 level, but this is not advised. Please fix the hardware.</p>\n"}, {'answer_id': 12059, 'author': 'pjleinen', 'author_id': 20192, 'author_profile': 'https://3dprinting.stackexchange.com/users/20192', 'pm_score': 3, 'selected': True, 'text': '<p>You need to level you bed.

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.</p>\n\n<p>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.</p>\n'}]
