Grinding Filament

[Speedy 0]

Hey Guys,

When printing objects that require a lot of retractions, the extruder on my Ultimaker 2 Go grinds up the filament and this results in slipping of the filament and under extrusion. I am printing 0.2 mm layer height, 50 mms, 230 degrees C. My spring tension on the feeder is as loose as possible ( white clip at the top) and the printer prints fine on prints with little retraction.

I am printing using Faberdashery Orange Fizz filament.

Is there a fix for this or is it just the nature of prints with lots and lots of retractions?

Thanks,

Speedy

Hi there,

Still having problems with initiating the test print.  The feeder takes in the PLA just fine and when we go through adding new material in, the material comes out as a thin strand. But when we tried setting up the test print, the grinder eats up at the PLA material and nothing feeds through to the main nozzle.

I've read up on some of the forum posts on here already about all the settings and still getting the same problem.
