    This takes place allot with PLA. ABS not so much if ever at all. In fact, this is my only problem with PLA that ruins my prints almost all the time.
    I thought heat crawling up the hotend was causing it but upgrading to E3D V5 did not help.
    Its not feed rate, feedrate looks perfect on the model. If i go lower it will leave gaps.

    i use CURA

    Anybody has same issue ?

    By the look of it, it seems that you were printing upwards and the nozzle reached it height and started to pool.

    Doesn't it need to adhere to the head?

    If you were spewing filament from the nozzle and it started to do this, then I would. Heck to see if any left over filament isn't on the end of the nozzle. Clean it with some tees era or setting. As it's coming out. Swipe it clean and see if it continues.

    Also try increasing temp. Maybe it coming out fine, starts to cool and you you get shrinkage, that's why the curling.

    I had this with 2 stock robo hot ends and this brand new E3d V5
    Its not the nozzle problem.
    I dont think its the flow problem because it flows just fine.
    If higher temp would help, i would see more filament coming and would have to decrease the flow, so its not the temp. I thought it was but setting PLA for 230 did not many any difference.
    In fact, i see this problem at 200c and 230c no difference.

    Problem identified.
    I tried to print too fast. Filament wont melt fast enough but i thought it wasn't the problem until i slowed down.
    Case Close !
