Print bad quality

Post by cloudprusa » Wed Aug 15, 2018 7:03 am

Hi, I did my first print with my Prusa I3 Pro B by a Thingverse sample cube design: https://www.thingiverse.com/thing:1278865.
I observed that print quality is very low.
Which could be the causes?

I attached 3 photos.

It seems like under extrusion.
Try to calibrate the extruder steps.

I think it's the extruder. I just bought the same model, and the extruder steps were by default something like 2600 (for me, that was over-extrusion and clicking noise).

The correct setting for me is around 400, you can set this on the LCD configuration too, but google and you will learn how to measure it and calibrate.

UPDATE: oops, sorry. I mixed it up with the Z calibration, that was the 2600 vs 400 value. Extrusion is a different setting.
