I replaced the brand of filament and now it's working pretty well. It's not 100%, but this was the first successful dual print of this file I've had. So does this mean my second extruder can't take the previous brand of filament I was using? That would suck since that's the majority brand of my filaments currently...

Is there anything else that this problem could be? I've added some pictures of the successful print, you should be able to see that there are some missing gaps, but nowhere near as bad as before
