Prusa i3 Pro C Extruder not working

[galott]

Hello,

when i print via USB with my PC everything is fine. But when i try to print from SD-Card the extruder don´t work. No nois or clogging. It seams like power off.
Extruder temperature and all other parameters are ok.
The reason why i would print from SD - the connection lost about 2-3 houres after start print job.

Here is my startcode:

; Default start code
G28 ; Home extruder
G1 Z15 F{Z_TRAVEL_SPEED}
M107 ; Turn off fan
M109 S240 T0
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
{IF_BED}M190 S{BED}
; Activate all used extruder
{IF_EXT0}M104 T0 S{TEMP0}
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
{IF_EXT0}M109 T0 S{TEMP0}

hope someone can help fast to fix the problem.

thx

Did you check the .gcode file was OK in your SD card?And was the heating of extruder and heatbed normal?
You can try printing the same model via USB and SD card,i guess it is the SD card issue if it still exists.

I will try that, actually i only try printing via USB for testing, but i willl try from SD Card now.
But i think that the feeder is the Problem because the stearing weels dont moving

So you mean the extruder motor spins while the wheel in the feeder doesn't turn?
If that is the case,then the feeder is the issue indeed.
