Hello, I am using: Anycubic I3 Mega Cura 15.05.6 PLA 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??? My Settings are [BASIC] Layer height:0.15mm Shell Thickness: 2mm Enable retraction" ckecked Bott/Top thickness: 2mm Fill Density: 75% Print speed: 40 Print Temp: 215 Bed Temp: 60 Support type: None Platform adhesion type: None Diameter: 1.75mm Flow: 100% Nozzle size: 0.4mm [Advanced] Retraction speed: 40 Retraction Distance: 1.5mm Initial layer thickness: 0.3mm Initial layer line width: 140% Cut off object:0.0 Dual extrusion overlap: 0.15mm Travel speed:60 Bottom layer speed: 40 infill speed: 60 Top/Bottom speed:40 Outer shell speed:40 Inner shell speed:60 Minimal layer time: 1.5 sec.
