so my printing success it growing, but my prints fail when they get to the infill stage and the nozzle become gummed up, if i print solid infill i get nice print quality on the prints i have done so far they get about 90% done then the nozzle seems to pull them off the print bed

[buzmal]

the photo below shows what happening when i try to pint with 30% infill, the structures seelf to collaps and the extruder gets jammed, printing on 100% infill seems to work but when the print gets to a similar height the nozzle pushes it off the print bed

Below the picture is the setting.

First layer also could be 100%.

[buzmal]

that has helped a lot, however my extruder still seems to randomly get blocked after about 20 layers of infill

[zhangxueyou]

Is the temperature high enough?

[buzmal]

i am runnign at 230deg for PLA

[zhangxueyou]

When you have got your printer work well, you should decrease the temperature back to 200 degrees, because higher temperature will make the filament carbonize, that may cause the nozzle blocked.
Note, the "first layer height" is recommended to be as same as the nozzle diameter, namely 0.4mm. As for the other layers, you can try 0.3mm.
