hey folks


We're finally done designing/making most of the 3D printer (here) but when I did a test run for the X and Y axis it had a curve in the Z axis...I'm not good at explaining so here's a drawing http://i.imgur.com/67W0KQ1.png
Red is the path the effector is following now, Yellow is the path it should follow, blue is the effector


does someone know what I need to change/adjust in order to get a straight Y and X axis?
We're working with the marlin firmware here by the way
