I am a newbie in 3D printing and I am not achieving the results I want .
I have a Creality CR-10 MAX printer and of course S3D as the slicer.
Currently I want to print some large flat parts for a RC plane - the parts are sized 280mm to 135mm and their base is 2.5mm thick...
The filament I use is colorFabb XT-CF20.
Attached pics 1 and 2 show the problems I have - the parts are simply unusable - they appear to have a open surface, the holes are uneven, there should be rings around the cut-outs...
When flipping over this part I was able to see that the surface which was on the printing bed was completely solid and closed - as I intended.
I made to small other parts on the same print - these were extremely brittle and I was able to snap off all structures on both of these parts easily.
So my question is: What did I do wrong here?
Some settings: Nozzle temp 260°, Bed temp 70° - FFF profile is attached.
*PLEAAAASE* help me!
THank you very much in advance!
BR and stay safe and healthy
