Hi,

it looks like there are lots kg retractions at the Top of the Building. Try to increase the extra Prime amount After retraction. 

 

Also Check if the filament je ground down by the Feeder. That ground down Area causes underextrusion as soon as it gets to the hotend.

Next Tipp would be lowering the Speed.

the design is ok there is no kg of retractions at the top because i printed same part in other printer and it was very nice.Also the speed is suitable .

it could be problem in filament down by the feeder.

 

but do you expect other reason ??

 

thank you very much

[problem in printer part]

the ultimaker 3 extended .

 

the big part start ok but at the end i do not know the problem . I try to increase the tension of the spring to tight the filament but same problem.

second problem is the under extrusion there is no problem with nozzle and the filament is new. 

 

give me your suggestion..

 

thanks in advance
