This is caused by heat creep , where the temperature of the extruder in the heat sink area gets warmer and warmer as the print progresses . PLA is susceptible to this in allmetal setups because PLA expands when warm , and so gets jammed in the cold part of the extruded when it warms . The solution to this is to increase the cooling on the heat sink , you can delay , but not prevent the issue by reducing print temperatures . Try to find a replacement fan that has the same voltage but greater CFM . <| sep |> Love should of got more shots after that first quarter <| sep |> The government has full control over how much currency is in circulation .
