Colorfabb Carbon CF-XT20

[nick_moss1]

Hi,
Are there any experts out there that can tell me where i'm going wrong trying to print with CF-XT20 Carbon from Colorfabb - I've spent hours trying different settings and I am getting better but still have problems as per the attached pictures. i have no idea what's causing this!

What printer are you using? It looks like you're getting lots of holes in the perimeters, which usually means your retraction settings are slightly off.

Hi,
I am using a Creality CR-10 Smart Pro.
My retraction settings are:-
Retraction distance 4.5mm
Retraction Speed 2400 mm/min

You could try increasing the retraction extra restart distance until the holes are filled in. If you start seeing blobs instead of holes, then you increased it too much.

There are other related suggestions described here:

Thank you so much. I'll try and see where I get to. Much appreciated.
