Combing leaving blobs on outside walls

[Link 33]

hi @smartavionics,

 

I am using your new 'not in skin' combing but getting blobs on the outside of the wall at these points (shown below), as mentioned a while back (and the reason i asked you to keep 'only in infil') Cura treats walls as skin rather than just the top and bottom layers and therefore doesn't retract in the walls, hence the material from the non-retract travel is getting deposited in the wall which is often too thin to hide it. In the screen shot below there is a strange 'kick' in the travel at which point the blob appears. Any ideas ?. could the travel be made to not perform this kick, or stick more to the inside of the wall ? i can switch back to 'within infil' and will get retracts in the walls which fixes the problem, but think you mentioned that Cura has issues deciding where infil is and hence the 'only in infil' can sometimes result in travls without retract actually in the top or bottom layers (skin) ?

 

Many thanks !

I think you just need to use a lower value of max comb distance with no retract. I typically use 10 or 20.
