Hi,
I'm quite new to ultimaker (approx 7 weeks). When I ordered, I also ordered a spool of white PLA. The Ultimaker included also a spool of ugly gold color. However, every print I made with the gold colored PLA was extremely well and very uniform.
Since switching to the white PLA, half of the prints failed because the filament was not fed anymore.
I printed Bertho's extruder drive upgrade from thingiverse and installed that. 3 prints further, filament still feeding.
But: the prints are very on-uniform. Every now and then, it seems there is not enough material deposited.
Could it be that the PLA from Ultimaker is no good? Or do I have another problem somewhere? Any help would be appreciated.
Pls check the attached photos. One shows my latest (still running test)(don't mind the colors: where sharpie marks to see if filament still feeding). The other shows the same gcode, but with the gold filament. Unfortunately, I only have the epoxied version left, but even without the epoxy layer, it was near perfect.
