Print quality degrades after fist few layers/ sort time
March 02, 2016 06:44PM
My printer has been printing very well in till to day. I printed out a marven and it looked very bad. I have printed a vase and done it many time to try to find the problem, but i can not find it. I have a photo of what it is doing. how do i fix this?

You have active print cooling? Because this looks to me to be too much heat, though it could also be the model that you are trying to print

Also, Is this pla or abs? And what temps you printing at?

Try blowing a SMALL fan across the bed after the first layer goes down.

What does the bottom of the bottom layer look like?

Also, I would like to expand on DaGameFace's suspicion of too high of a temp...
Check and make sure that the thermistor is not broken, or reporting temps too low. If it has partially come out of the hotend (EXTREMELY BAD FIRE HAZARD), this would cause the hot end to get WAY hot before the thermistor registers the target temp. What about a heated bed? the whole part does look a bit soggy, so maybe the bed has the same thermistor problem or is just too hot?
