Print quality improvement

Hi Everyone,

i would like to understand what's wrong with my print.
This is the first print of a dice after the calibration. I wonder if its too few plastic getting extruded or mechanical problems i'm facing ?!?

I am pretty new to 3d printing in general. I am running a delta Kossel 4020 from hkbay with changed electronics (RADDS 1.5 + RAPPS). The whole thing on 0.9° steppers.

Maybe one of the enlighted people might give me a hint whats wrong with my setup currently.

The picture looks worse ... in fact on some sides the dire looks fairly good. ... going to make another picture

Thanks for your help

Here a little better view of the "good" sides

I'd start looking at temps and extrusionsrate, have you set the vref for the extruder stepper "correct" so that it gets enough current?

Thanks for the input ....... I have to say its finaly working .... i dont know why but i had to increase the flow rate a lot .... i followed the triffid hunters calibration guide for extrusion now i'm at a point where in NICELY print with an accuracy of 0.05mm wich i think is perfect for my slightly uncalibrated printer (I LOVE deltas . around the center i have an area of about 8 cm diameter i can print fine in ... now have to fine tune the towers ... THANKS everyone for the help .... super happy .... happy to post some pictures when the first objects come out .... looks sooooo sweet now
