I honestly don't know how to answer your questions. I'm using the machine with the settings from the previous user. I'm using Repetier as a slicer, which uses either Cura or Slic3r (I can't remember which I used for this gcode).

As for settings, I don't know what the relevant settings are or how to find them. I'm working straight from the kossel display. I only have access to linux computers and I have had a lot of trouble making all the software work right and also seeing the printer.

Filament is 1.75 mm PLA. Do you need any more details than that?
