just as a hint, i liked the origonal firmware a lot better. i upgraded it and then it printed the 1layer 1mm too high on cura and couldnt fix it. . had to switch to repetier host and slic3r and am having a really hard time. i can perfect a print but it takes soooo much tweaking, its almost not worth it. wish i could get cura to work again. that and there is no one else with these things, they are so new.
