What could be wrong there?

Good evening,

 

I started a new print.
Everything went Well.
PLA, 215°, 0.15mm and 33% fillin + support
This is a standard  Exiii/e-nable Robotic arm piece and I have no doubt that the stl is OK.


As you can see on the 2 latests pictures, most of the print is very nice and fine.
At some point only one small part of the print has started to be degraded.

 

I don't think it's an issue with the temperature, nor the general parameters of the print, or the full part will not be OK.
I can't see any parallelism issue on the printer itself ; I can uselly print properly in that printer area.

I'm wondering if anyone have this this already?

    Well,
    I might be wrong. I now have a difference while printing an3DBenchy.
    On left the result while the nose of the boat is turned left. On the right, when it is turned right.
    So :
    -Check parallelism
    -Clean the nose of the head

    -recalibration

    hope it's fine now. I'll let you know.

    fan.  It matters where the fan is.  It matters where the fan is blowing when the nozzle is printing the rest of benchy other than the bow.

     

    If the fan is on the left side of the head only, or right side, etc it all matters and that is what causes one orientation to be good and another to be bad.

     

    Also the position of the part on the bed - if the part is near an edge of the print bed and if it is a heated bed then that can make a difference.

     

    I guess I could say "air temperature and air speed" is what the issue is.  Or how well the previous layer cooled down before printing the next layer.  But usually it's just "fan" asymmetries.

    Thks for your replay gr5.
    I can confirm that I still have the issue after the tiny changes I made.

     

    I'm double checking what could be possible in term of fans for this printer brand.

    Best regards
