First print & question reg. quality

[Bossler 8]

When I look at the first print my UM3e produced today - a benchy of course -

I see two things I do not like too much:

- the diagonal lines visible at the side of the cabin

- the rough surface at the lower part of the benchy

 

The first issue I already have learned this might be a problem of the UM3 and may be related to the way the stepper motors are driven?

 

The second issue - rough surface at lower layers - is a bit tricky.

I did use the silver UM PLA that came with the printer and the standard profile for that in Cura.

So bed Temp was at 60°C, print temp was 205°C.

 

Does somebody have some hints to improve?

Hm, no idea whatsoever anybody?

I really do not like the lower layers;-)
