I have been doing some prints with large flat panels on them, and always get some inconsistent levels where the surface has a hole or boss, and always get pass lines showing through. This is a Taz 6 using cura. Happens with ABS as well as PLA. These show up on sublayers too, which show through the final layer, making for a pretty sloppy looking surface.
For the pass lines, Is there a z-hop setting i am missing or something?
For the levels/layers, is there something i can try for layer height, or line thickness? Currently using a .5 nozzle. Have switche to a SS micor swiss nozzle, but the issue has always been there.
