250 degrees is too hot for PLA. Something is wrong there.Makron wrote:Printed over 10kg of "cheap" pla last month from reprapworld, everyone finds it cheap but it works PERFECT. (and just 18 euro a kilo)
60 rings printed with the e3d hot end with no problems and jams at al.
205 Deg Temp , first layer at 100% speed and the rest on 250%
So dont say that its not good for normal printing.
Are you actually using this extruder mount? (which is what the topic is about).
