While using the bed levelling wizard in Cura, if I press either of the up or down buttons it always goes down and by an amount much larger than what I told it to, yet this morning when I was fiddling with the Ulticontroller for a few minutes before I left for work I discovered that its auto home option raises the bed just fine(actually a bit too high, need to lower my Z switch, whoops), which leads to the assumption that it's something wrong with my Cura install, not with the printer.
I'll give Pronterface a try when I get home tonight, cheers.
