l'estrusore non si scalda(risolto)
March 14, 2014 05:15PM
ho la megatronics v3 su la prusa i3

ora ho un problema ... con lo sketch di test della v3 funziona l'hotend poi carico marlin e non si scalda come mai ? ho gia provato varie regolazioni ma proprio non ne vuole sapere si accende il led dell'estrusore ma non scalda non capisco

questo è lo schetch

Controlla con un multimetro se hai i 12V sui contatti della resistenza di riscaldamento mentre il led di notifica è acceso.
La lettura della temperatura che dice? E avvicinandosi all'hotel senza toccarlo è caldo?

non c'è voltaggio e non è caldo


ma funziona tutto perchè se ricarico il test funziona bene e legge la temperatura senza problemi

mah onestamente hahah non saprei indicartelo ....
ho caricato lo sketch di rrw ed ora scalda ma non estrude il motore ma temo che sia un'altro porblema

Mi aggrego alla discussione per non aprirne un altra.
Prusa i3 con mega 2560, ramps 1.4, marlin v1, repetier host.

Quando mando in stampa qualsiasi oggetto con repetier, scalda l'heatbed ma non l'estrusore, qui le prime parti del g-code generato da slic3er 1.0.1

appena do il comando di avvio stampa repetier mi dice "riscaldamento estrusore" ma la resistenza dell'estrusore non viene alimentata, mentre se a stampa non avviata impartisco il comando M104 S205, il led su ramps si accende e l'estrusore si scalda.

Con Cura invece sembra funzionare tutto, di seguito di codice generato:
