Weird spiral pattern on print

Recommended Posts

I think maybe not enough cooling.  Fan is working?  Have the other successful prints had a larger X-Y area, thereby allowing more cooling prior to subsequent layers?  Maybe try a combination of slower print time, increasing minimum layer time, and maybe enable Lift Head?  I sometimes print 2 or more small area parts to provide more cooling time and pick the best one when its done.

To me this looks like some feeder/extruder issues.

I would do some atomic/cold pulls. Check the consistency of your filament. Manually push the filament into the hotend to see if the temperature is right.

I'm not sure what filament I'm using

ummmm, same filament that was successful so far? The reason I am asking is if you went from a low temp filament to a high temp filament, that would create massive underextrusion.

 

The version you show is a previous version that is before my time. Sorry, but there are those who are familiar with it.

Yes, when i bought the printer a year or two ago I bought a few spools of the same fillament. Thats all I've ever used.

Just ruling out things....have you tried the hot and cold pulls and see if there is a clog?

Please show the other settings as well.  And can you zoom in on the part more?  It looks maybe underextruded but I can't tell.  and check your part in layer view - does it look fine there?

 

I can't tell from the photo but the only thing that makes sense to me is underextrusion.

 

Also when you post your settings, tell us what your nozzle diameter is.
