La configurazione della stampante è la seguente:
3Drag v1.2
Raspberry PI B + OcroPrint + WebCam
Megatronic V3 + DRV 8825
E3V6 + Type K Thermocouple
Power Supply 12V 30A
Glassplate 3mm + MK2B
GT2 Belt - Pulley 10 teeth - XY 200 step/mm
Z-Endstop micrometer:

Preparo il gcode con repeiterhost e lo carico sul raspberry tramite interfaccia web di OctoPrint,
Riduco ulteriormente la velocità di octoprint al 60-67%
Riguardo la temperatura non saprei che dire, a parte che vi assicuro che non fuma ...il pla esce con una viscosità morbida, non fa fili ne sbrodola.
Il pla che ho usato (non è quello della foto ma il problema è lo stesso) è di vario genere Nus Nus, esun e Real
Più sotto elenco i parametri di slic3, ma nel frattempo mi è venuto un dubbio sul fatto che ho abbandonato l'utilizzo di questo oggetto
http://www.thingiverse.com/thing:492067 che potrebbe esserne la causa.
