Issues with print Prusa i3 infill breaking and causing clogs I'm having some issues with my Prusa i3 prints. I'm trying to print the default beer opener print that came with the Prusa's memory card but the infill will break causing clogging and now allowing the print to finish. I've attached a picture of one of the failed prints.



I've checked Prusa's website and tried tightening the extruder gears and made sure the gears are clean. I'm using the PLA sent with the printer (1.75&nbsp;mm) and with a default G-code file so I'm fairly sure it is a hardware issue, but I'm not sure what the issue could be. 

Here is the link that I've used to help me troubleshoot.
Try calibrating your Z again. It is hard to tell based on the picture, but it could be too close to the build plate, and thus is dragging while crossing the infill section, or it could be too far away and thus is not getting good layer adhesion.
