I have printed at least 24 hours of printing successfully on the i3v 10". However, it is now causing and issue I don't understand. This is what the print looked like:

This has happened multiple times. This problem arose when I tried to print something rather big and after a few hours of printing when I got back I noticed it wasn't printing anymore. I thought the head was jammed and cleaned that up. The printer seems to extrude fine so I don't think that is the problem.
Looks like your nozzle is to close the the heat bed I like it to be .004" and i have also noted that after a few hours the nozzle clearance will get tighter and have to reset to .004"
I've had the same thing happen. I'm always amazed at how out of level the printer can become after a few prints.
Okay, so I totally recalibrate my printer and now this is what the first two layers look like.Quote:

Also, the bottom part is still spotty. Does that mean that that corner is too low and needs to be increased? There is also a couple of spotty areas on the top area that are blank.
Is it possible it is the filament?
It could possibly be the filament. We're did you bought from.
Makerfarm. But there black PLA filament was crap so I am starting to get suspicious of there white filament.
Maybe some more questions. Did you check the clearance (leveling) of the bed at locations near each corner? I use very thin paper and go for just a little drag on it. I also print a skirt like you did and if it does not look right, I stop the print right there and adjust. In your picture, if that is a two pass skirt, I think you are too low.
Also, you haven't said anything about print temperatures and other settings (speed, etc.). I use a hollow cube which is two layers thick on the edge to check new filament. As it prints up, I adjust temperature and flow rate to find a happy place. It seems that it changes sometimes from one filament spool to another.
I got a bad roll of black from Makerfarm as well. Colin replaced it free for me. I have not any problems with any of the other colors, including the white.Quote:

I print 3 skirts just to get the ink going. I have been using this filament for quite some time at 80 degrees for the heat bed and 185 for the extruder. I think that is the set suggestion by makerfarm where I got the printer. I have no clue how to change the flow rate, I tried doing it on repetier but I don't think it worked.
I have printed PLA that low and as high as 220. I tend to run higher with the E3d. You can adjust flow in the slicing programm or on the fly with LCD. Also, make sure you are not dragging the filament. I had problems with filament drag, both from spool turning effort and as the spool got towards the tighter winds...from that.Things aren't always obvious and it does take some time to figure it out. You might also want to design a hollow cube as I described above. It helped me sort out some things.
What is filament drag? The problem as far as I can tell (now) seems to that the filament isn't coming out fast enough. I don't really understand how that is possible since I haven't changed the settings at all since original creation.
It involves the parts of above the print head. If those parts get too hot, they heat the filament that is above the nozzle. That makes it yield and expand radially as it is being pushed down into the nozzle. If the filament expands enough to drag on the bore, it will jam.
The usual cure is a fan blowing on the print head.
I refer to filament drag as anything which makes it harder to pull the filament off the spool. Includes spool turning drag and also the requirement for more pull as you get towards the center of the roll. Tighter set filament, near the center, is harder to pull then filament near the outside of the spool.
while some of these might be slight, it can be enough to put you over the edge.
All the PLA I've tried to print with needed to print at 190 or higher. At 180, the infill would be too brittle and not adhere to the previous layer.
