First printer, first print.
It took me about a week to setup in my spare time, and now it's working. As spected, the first print wasn't all that fine.
However, I'm having trouble finding out my problem. Here's a pic of what's happening:
As you can see, the printer actually prints fine half of the model. But the bottom half gets messy.
Reading on internet and watching some videos, people say to try another slicer program, and so I did. The first try was with Slic3r prusa edition, and the second one was with Cura. Both behave similarly.
So I guess it's not some simple slicer misconfiguration, as there's a good print up there. And in the same sense, I don't believe is some bad calibration, as it should affect the whole print, and half the print is fine.
The printed is calibrated to my knowledge (z axis, bed, and so on), and lubricated, as I had to test and measure it A LOT before being able to print (it gave me a few mechanical problems after the first setup, that were fixed by calibrating).
My first hypothesis is that there may be some problem with the original SDL file. I've downloaded it from some of the popular model sites (don't remember which one). That would be coherent with both slicers giving similar outputs.
My other hypothesis would be that there is different lubrication on different points of the z axis. But I've checked that out several times and didn't find anything weird.
Being a newbie, I bet this is a common problem. However, searching for it has been shown to be problematic so far, as I got a lot of people with other problems different from mine. Maybe someone here knows what's going on?
Thanks in advance.
