Some issues with printing.

Hi, I just started my 3D printing and am printing parts for the Filastruder.

However, for the 1st and 2nd layers, sometimes some parts on the same layer would not be as dense and filled like the other sides. How to rectify?





For empty spaces, there seemed to be unwanted parts that needed to be trimmed off, is it because the speed of the extruder is too slow?





There are some warping here, is it because of the fan and cold temperature?

 

Ive been running across same as picture 2. I think the bed not being flat is one problem. Maybe slowing it down would help...my extruder wont heat up...i was trying to fix that same issue. Try sticking a shheet of vinyl on the glass...so far that has helped the most.

 

Is your heated bed on? Turning it on to 60 should reduce warping.
What temp is your hot-end set to? Consider raising it if its at 180 to 190 or 200.

Also, check your hobbed bolt to make sure there is not plastic debris interfering with your feed. Looks like the gaps are caused by it not extruding. Could be a slight jam that gets sorta cleared after a bit. Perhaps increasing temps will help reduce the amount of force it needs to shove the filament through.

 

Great idea, I used to set it at 190, then to 193, I should try 195 instead, a 10 degree jump might be too much. Thanks.

My heated bed is not on, maybe it is the fan nearby.

 

The fan nearby could definitely do that. His idea of running the heated bed is a good one.
