Hi UlrichC-DE It seems you are right. It only happens on a large print, where there is lots of long distance movement of the print head. It seems filament was pulled bit far and I can hear noise when it retracts. The layer height setting was between 0.2 to 1 mm with 0.4 print head. I didn't change material, was using PLA (ultimaker) the whole time. Fan was on. First layer seems fine, the problem occurs duing the infil progress. I will keep observing this. Many thanks for the help.

Hi UlrichC-DE I have tried different tension setting for the feeder, all the way from top, middle and bottom, and I have no luck with the material grinding. However, last night I have turned off the flow sensor, it seems to print fine now. Many thanks

Hi I have got a S5 for about a week. However, when I print some large job, after the 1st layer, I have the error massege on the screen says" material is empty" whilst plenty of material is on the spool. I pull out the filement and noticed there was significant grinding. I did some research and have disassembled the feeder and cleaned it. Set the tension to the lowerest. But the same problem still not solved. So far I am having problems with PLA and tough PLA, haven't tried other material yet. It seems the grinding happened after retraction. My retraction setting is "Retract at layer change and minimum retract travel 0.3mm" Please help, this is a very expensive printer and seems I can't use it's full potential. Many Thanks Sheng
