Hi all, Ive some issues with tiny dots while printing and im hoping you can help!
on the two photos you can see the walls printed beautifully but the half dome on the top has some very noticeable defects. As this is for a client and needed to be close to perfect I decided to take the long road and used 0.15mm Visual preset with the only change being to add supports. I was sad to see after waking up on the morning the print finished to see the small dots on the top of the dome.
I checked cura and found that there are travel lines that exit from the dome and go around to the other model. I tracked down that the travel lines are exiting from the outter shell because Travel> avoid supports while traveling is ticked. Why is this? it seems to be partially responsible for the dots i think and it seems odd to me that the hotend would travel over the outer layers, especially on a visual setting. Is there a valid reason for this?
Once i took that setting off i printed another part of the same type and found that there were still dots! after zooming in very close i found there are also small black loops that exit and enter from the outer shell back into the model! Its literally a travel line that for no apparent reason goes to the edge of the model and does a little loop.....
Please let me know how i can get rid of:
A Travels over the edge
B The small loops that seem to server no purpose other than making small dots on the outer surface.
Ive attached the 3mf file also in case someone wants to check it out.
Thanks!
