I have been in this "process" of building a kossel mini. I printed the parts with Wilson Ts and ordered al my parts from tridprinting.com I am to the part where im trying to do some calibration prints and now im stuck with an issue.
While doing my first couple prints everything I tried to print a 5x5x5 cube which was a small print but came out like crap because of my home made rollers. Fixed this and now I moved on to printing the nickel calibration test and its all sorts of stuck on the dumb. The ramps 1.4/arduino combo is from sainsmart when I print and it moves to the -Y the axis will lift off the bed. I supplied a video but im completely lost with why it is doing this.
