Issue with printing PP

[mike4it 0]

Hi,

 

I have an issue when I print PP. As you can see on the pictures there is one side (bottom side) of the print that is a real mess. That area is where the head gets up and down to change position. Is someone ever experiences some similar issues and could help me with this ?

 

Here are the settings I used:

- fan speed at 75%
- infill density 105%
- build plate temp. 100°C

- printing temp. 230°C

 

I also tried those settings but got the same result:

- fan speed at 0%
- infill density 125%
- build plate temp. 85°C

- printing temp. 210°C

 

Thanks

I never had any isue printing PP but looking at your pictures it looks like under extrusion. I would change rectraction distance and change the seams location to random.

Thanks for your answer.

I tried to set "Z Seam Alignment" to Random but I still get the same result...

 

Retraction Distance is set to 6.5mm
Do you think I should change this value?

 

I also tried to set Retraction Extra Prime Amount to 1 mm3 but same result.

 

I don't think it's under extrusion because it only affects one area of the print. I also checked the bed level.
