Material will not extrude

[RMISSION 0]

I cleaned the print heads and am trying to print a part. No plastic is extruded. I removed the filament and the filament was worn down by the feeder wheel. I also tried to manually feed the filament during the program but it would not feed like there was not enough temperature to melt the plastic. The digital read out says 260C at the start of printer head cool down. What could be the issue?

Hi,

 

which printer do you use? How do you feed the filament manually - do you heat up the extruder on the printer or through Cura or another slicer?
