Hi Friends,
I am new to this reprap forum and 3D printing as well. Just got my new 3d printer, at times it prints fine but at times in the middle it drifts, i mean the next layer does not fall on the previous and it happens at times in x-axis and at times in y-axis, I have checked the belt tightness and also if it is not getting excess supply but both are fine and moreover at times it prints objects just perfect with the same settings. Please Advise......
