printer is retracting a lot

Posted · printer is retracting a lot


I am using:

Anycubic I3 Mega

Cura 15.05.6



My printer has started retracting a lot. I went into Cure / Info/Filament to run just the extruder and it does the same thing.

It will run forward a little but not extrude anything /or very little then retract.

I have:

* unplugged the unit.

* reset the unit.

* switched to different stl files

* changed settings up and down in Cura


Any ideas???
