Infill hex pattern not consistent - printer moving too fast?

[Nathan Davis]

I just got my Mbot cube this weekend, and have been testing it with a few first prints. I've noticed that while printing objects (using PLA) that have hollow sections and the printer creates the hexagonal infill pattern, the plastic doesn't have time to adhere to those sections on some passes. I'm leaning towards the possibility that it's because the extruders are moving too fast over the pattern. The outer shell of most prints looks good for the most part, but internal structures are pretty sloppy. The outer shell seems to also print at a slower rate than the internal. Would slowing down the feed rate fix this? Or is it a temperature issue? Temp is usually 230c, but I've also tried 225c and had a similar result. I guess I just need some advice on which settings to tweak.

I think a really good example of this problem was with the iPhone 5 dock from Thingiverse. It has a channel through the bottom for a charging cable, and as it was printing the infill, the strings of plastic that didn't adhere correctly basically blocked the channel. Adhesion of the base doesn't seem to be a problem, and I'm getting fairly consistent extrusion (I think).

I just posted it on the other forum. Thanks for the suggestion! I look forward to joining the discussion.

If your using S3D, then i think there was a default once for "use random infill placement" under infill on the process. Can't think of a reason you want random infill placement unless your printing something like nylon or ninjaflexx and want more spongyness. Anyway, disable that and it should line up.

Check your settings and report back, i had the same issue and have since fixed it.
