Ultimaker Original+ feed problems

[clarkman 0]

Hi everybody;

We are just getting started, but having issues with feed and flow of filament.  We are experimenting with 10x10mm cones to get our feet wet.

Using all default settings in Cura (latest version), and light blue PLA shipped with the printer, filament oozes from the nozzle until the print starts, it makes a layer or two and then flow slows/stops.  Pushing filament by hand, it comes out.  Cancel print, head starts oozing again until cooled.

 

• Feeder purring and advancing - check
  
• Head fan was coming on and dousing temp, ruining base of cone - turned off
  
• Press feeder spring wheel against filament - variance but not working
  
• Tension/Spring screw tighten and loosen - not much diff
  

 

The odd thing is that last week it made the cone.  Under extruded (gaps), but a cone.  Now it starts out well, but ends in little mounds of under extrusion.  Head temp is holding.

What have we done wrong?

Thanks
