Re: Can anyone in ChCh help us out with a little fillament for the weekend ???

Yes the bed dimensions are set in Marlin or whatever firmware you are running so it won't go past the limit switch. Press reset on the electronic board and try again. X and Y limit switches are not critical so you can set them with the power off just by ear with the micro switch click. Set Z high to start with and lower it to get closer to the bed. You guys have a great little 3D community down there in Chch.
