Ender 3 print is skipping and dragging up base print lines

  • Failed first and second layer of print



    I have only been able to get my prints this far. They just can’t stop skipping pulling material up towards the nozzle which then melts pulls of another random bit. At first I thought it was motor skipping, so I strengthened the spring, but even after that and calibrating the bed, I couldn’t figure out exactly how to fix this issue. Hopefully someone has some idea what is wrong.


    Your question comes down to insufficient bed adhesion, there are a lot of questions related to that issue. You could start with proper leveling and nozzle to bed distance or using a glue stick.

    Don't overlap the blue tape, that is REALLY bad. Some lines do seem to overlap. And I was much happier with the BuildTak clone than I could ever be with the blue tape. Plus,if you really want to work with blue tape, pay it down in the Y direction, so the edges don'T scrub at the frame and induce layer shifting.

    It's probably bed adhesion, and that can be related to bed temperature, accuracy of Z-axis zeroing, correct extrusion rate for first layer...

    @Trish - Most things I've read suggest putting the tape at an angle to the bed. Definitely should NOT be overlapped, though.

    What temperatures/type of plastic are you using?

    I’m using PLA at 205 with a bed heat at 60. It’s what I was told I should use, so I figured that would work.

    Thank you guys for your input, I will try your fixes as soon as I get some free time and let you know which of them was the right fix

    It's all black magic, and best settings are machine-dependent. I've heard from other forums that any temp above 50C will reduce the adhesive strength of the blue tape. It depends a lot on the accuracy of the temperature sensor and the uniformity of temperature across the print bed.

    So, contrary to what people were saying, my problem came from my spring that controlled filament flow. There was too much tension and it caused motor skipping. I did get rid of the overlap with the blue tape, but otherwise I had to clamp down my spring and that fixed the issue.
