So here is my first print on my brand new Prusa Mendel!
Actually, my first prints had each layer offset at random distances (I lowered the default_acceleration as suggested on the wiki, and the problem went away).
So this was at 0.4mm layer height with a 0.5mm nozzle. Not bad, but the top block appears to have had issues. I pretty much used all the default settings in Slic3r.
This was a calibration object I downloaded from Thingiverse. Each step is 5mm high and 5mm wide.
Is the top layer messed up due to limitations of my nozzle or is there something I can do to improve it?
Any help is appreciated. Thanks!
