Unwanted seam appearing in prints on FFCP
Hello, I encountered a problem in my prints.
Here are some photos:

I am using Simplify3D as a slicer.
I printed the handle for nylon bags a few times and every time the seam was there. I changed the orientation and the seam didn’t disappear.
After that I printed 2 coat hangers and again the seam was there.
The Z seam is in another spot and has nothing to do with the continuous seam seen in the pictures.
Is this from the slicer or the printer? Anyone encountered this in their prints?

The seam on the bag handle looks like it's from where the extruder starts and stops for each new layer. The seam on the hook looks like it's the internal fill you're seeing from the outside.

This is the Z seam that (I placed it on the back of the model at the same spot).

The Z seam from the coat hangers is randomly positioned and the model has 3 perimeters.
The inside perimeter fuses with the inner perimeter at another point, just above the strange seam.

Is there more than one seam on a part?

The coat hangers have 2 unwanted seems (you can see in the pictures). The Z seam is placed from the slicer in random places.
The bag handle has the Z seam on the back and the unwanted one on the front.

To be honest, I just think it's a perimeter wall showing through some transparent plastic. Try printing with more top layers.

This model has 3 perimeters and it was printed on it's side. The infll is youching the inner perimeter a little above that bulge.
Here is the infill touching the inner perimeter:

Oh sorry, I did not see the bulge before.
Can I assume you printed that hook on it's side, and the other object standing up tall? if that is the case it looks just like my flashforge prints most of the time. If you are using simplify 3D im pretty sure you can change the starting point of every layer.
If the starting position is "aligned" it will start the layer always from the same spot as you know, which can create that seem - but it's odd yours started doing randomly - it was ok before yeah?
mine has done this from day 1, so I use other programs to slice like makerware (it makes pretty good X3G) or a few others, but to be honest I only use simplify3D for my kossel and prusa now. I've never gotten better prints out of S3D so I stuck with what worked best for me.Hex3D - 3D Printing and Design http://www.hex3d.com

Yes, the bag handle was printed standing up and the coat hangers on one side.
For the handle the point for the Z scar is where it's supposed to be. That bulge is not on the exact opposite face, it seems random.
For the coat hanger two bulges emerged on the two small faces.
Here are more photos of the effect:

I will try to use other slicer, even though FFCP recommends S3D...

Update:
I found the culprit.. it's the acceleration
Left one is without acceleration and right one with acceleration.

It's a firmware problem and I can't print without acceleration because my prints will last x5
How can I fix this?Last edited by Horia; 03-01-2016 at 06:49 AM.
Printing time- Is this right?
