 +With PLA the extrusion stops after some seconds. Pulling filament out and reinserting doesn'​t help for long.
 +
 +**__Resolution:​__**
 +PLA sticks to steel. If the hotend is rough inside, it might stick even better. There are two ways to solve this problem.
 +First, rise the temperature about 5-10°C. ​ Second, season your hotend by putting oil into it, as described on this [[http://​johnridley.blogspot.de/​2014/​06/​nozzle-seasoning.html|Blog]]. Simply dip the first 5cm of the filament into canola or olive oil and push it into the hotend while it has about 230°C. Then (manually) extrude some centimetres. Pull it out, cut the end and insert it again without dipping into oil. Again extrude some centimetres and also pull it out afterwards. Repeat this process about 2-3 times. Please notice: This only works with full steel hotends. Never try this with a J-Head or any PEEK/PTFE containing hotend.

 +**__Problem:​__**
 +The nozzle temperature could not be achieved.
 +
 +**__Resolution:​__**
 +This is a problem which only occurs at elevated temperatures. The fans are very powerful. Especially for PLA you need very good cooling. For ABS or nylon you don't need that, so it is recommended to reduce the speed of the fans. You can either set it directly on the menu under "​tune->​fan speed" (fan2 speed) or "​contol->​temperature->​fan speed" (fan2 speed) or you adjust the start gcode in slic3r (printer settings->​custom G-code) by adding a value from 0 to 255 after the "​S"​ in "M106 P0 S200" / "M106 P1 S200", where 255 is full speed and 0 is fan off.
