    Hi, well, as you can see this is my problem, i try to print with ABS at 235ºC, and the Bed at 105ºC with simplify 3D.

    Obvioulsy the fan its off.

    I think, could be the problem for not having a cage? (for control better the temperature)

    Normal ABS behavior without a heated chamber.

    You can likely improve on this by some combination of:
    1) reducing the infill percentage
    2) lowering the nozzle temp a bit
    3) make sure there is no air movement and use a warm room (box around the printer if you can)

    Finally, is there some specific need to do this in ABS? You might want to consider a different filament type that will not want to warp (PET, Nylon, PLA variants like woodfill). That particular model would look awesome in woodfill :)

    Whats the ambient temperature? If you have a hexagon it might be worth increasing the temperature to around 245

    Also it's a good idea to drop the bed temp down to 80C after the first layer.

    As always, an enclosure with ABS is ideal: http://www.printedsolid.com/shop/3dprinters/r3dhouse/

    I tried to make an enclosure, also i put the config for low the temp at 80ºC after the first layer. But as you can see, the result was worst.

    Tonight i gonna try do not slow down the temp, and also i gonna reinforcing the enclosure.

    If you have an all metal hotend I suggest printing at 250C

    Good general advice (much of which was already said here).

    It is ABS...

    Specifically yours was inter-layer warping (not just the bottom layer curling up) and a lot of the answers don't help with that. ABS warps as it cools. The gentler the cooling, temperature change goes, the less it will warp. That is why I suggested dropping the nozzle extrude temp rather than raise it. The lower temp you can print ABS at the less of this you will be subject to. A heat lamp can also help if you direct it on the print (but that usually is aimed at only one side so less helpfull).

    Corner/edge/bottom layer warping is a different beast and the 'mouse ears' or rafts can really help with that.

    Oh, and this was 90% ABS:

    so you can see it is doable.

    You can also see (by looking closely) that there was still some edge warp but we made it work with the model.

    I gonna still trying to improve my skills!

    PD: And one question more, my Robo its the Robo3d R1, i bought this november, as i can see, the hoten its all metal, but i'm not sure, because i have not seen a "hoten of not metall". Its a little silly question, but i wanna see the differences between my hotten and ED3 V6 who everybody talk about.
