I have replaced the control knob, the main board, and added a dual z axis, and replaced the glass plate with the magnetic metal one and still haven't been able to print any right. if it even begins to start looking pretty good it warps, skips spots, and either comes off and the plate or keeps going and not doing anything but make a bunch of string. I have done everything that I was told to do, leveling and such and haven't been able to get it completely leveled, and have wasted a whole spool of more of filament. I don't think I would recommend it to anyone, and won't be buying anything more of these.
