Hello !

I really need your help.

I have built an Anet A8 printer. First of all, I printed a circular fan for the nooze.

After this upgrade, I printed a first "T corner" piece who was just perfect. I printed a second one to have two of them on each vertical Z support.

But... The second one was uggly. The diagonal (hangover ?) was like an inversed scale while the first one was really clean, increasing bottom to top nicelly.

I do not understand what has changed between the two prints.

During the second print, the borders of the piece are not flat but they are more hight than the printing surface.

I have tried many things... downing the temperature, slowing the printing speed, with no success.

Because of the first piece who printed well, I know my printer is able to do it, so I'm searching a way to calibrate my printer.

  • Bed correctly adujsted
  • X axis parallel to bed.
  • printed a new fan for noozle.

Should I have to force fan speed ? I see the fan doesnt work everytime, but it turns sometimes (depending on gcode, I suppose)

I need your help !
