Wall gap

[prather 0]

First, let me say that I'm very impressed with Cura. Well done, Daid! I'm finally printing recognizable objects with my Ultimaker! This machine is stellar!

The only problem I'm having is with the infill not connecting with the walls. I printed this http://www.thingiverse.com/thing:20895.

Notice the gap along the long sraight area. The infill seems to be offset in places, but connects solidly in others. Overall It was a very solid piece, but I'd like it to have more overlap. I've increased the feedrate (by understating the filiment diameter) with some sucess, but I don't feel this is a good solution. Any suggestions?

not a very useful response I realize, but 'me too'. it seems to happen more often in one axis than the other. does rotating the piece before printing make a difference for you?

I also thought that underextrusion might be the issue and adjusted the same parameters as you but now wonder if it might be alignment or belt tension to partly blame.

you can change the overlap with perimeter setting in Cura which might help slightly, but I don't think it gets to the root cause of the problem.

Hi

This is usually caused by belt tension, or lack of. Check all 6 belts and tighten where necessary.

Actually I think it was due to sitting idle for a couple of weeks. The belts seemed to assume a static shape, but after a few runs, it's working great! I did tighten all the belts, though. Software was not the problem.
