Hi everyone,
Have just finished assembling my new kossel mini. I have been trying to print the 3Dbenchy just as a test print, however I am running into under extrusion issues in areas of the print where the print area is fairly small.
Printing at 50mm/s the lower half of the print comes out perfectly but higher up the print where the print area is smaller the filament is under extruded and just comes out in little blobs. However if I turn the feed rate down to 60%, (using repetier host) the under extrusion problem is significantly reduced and the print returns to near normal!
Any suggestions as to the cause?!
Many Thanks
Sam
