Hello everyone,

 

I just did maintenance on my printer (grease, check axes, belt tension and so on) and I ran a couple test prints to compare with the one I did the last time, in June, and there seems to be a slight problem: as you can see in the picture below, the Z on top of the black cube on right cube is clear and has very sharp corners. This cube was printed in June after my previous maintenance. The orange cube and the black one on the left were printed today and the Z is much less defined.

 

 

I had the same problem before doing the maintenance, as I was testing my 0.6 solex hardcore. The cubes in the pictures have been printed a standard 0.4 UM printcore. The ones printed with the solex 0.6 hardcore show the same problem, but worst, I guess because the diameter of the printhead is bigger.

 

I'm not too sure what is causing this or how to solve it, any help from the community would be greatly appreciated. Thanks.
