The Y-axis socket for the Idler may need to be a tiny bit larger to allow smooth insertion of the metal idler. It has been a hassle during the Y-axis Alpha builds.
@west I can but this is a slice for mini 1 correct? The x and y steps per MM will be different than the alpha parts printed on mini2. I feel as though whatever information you are attempting to gather from this gcode will not be comparative data as none of the parts used for alphas were printed on mini1.
Regardless, how many parts do you need?
