Too many retractions?

Posted · Too many retractions?

I was trying to print Mac OSX Recycle Bin  with no success. I am using default UM2+ retraction settings (6,5 mm @ 25 mm/s) with ColorFab PLA/PHA at 208 C and 30 - 40 mm/s print speed (0,16 mm layer height). Feeder tension is set as default (in the middle).

 

After 10% of progress extruder stopped feeding filament because of grinding. I know this model requires a lot of retractions, but I found interesting how filament got grinded. The feeder teeth was getting deeper and deeper in filament across the length of 50 cm. Filament flattened from 2,85 to 1,9 mm and than grinding occurred.


Is this usual behavior before grinding?

        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
