How tight are the clips supposed to be? I tried out the "both clip" and the width of the power poles was too wide to fit in the connector. The roll pins didn't survive the support material trim and my attempt to insert the power pole connectors, but I didn't expect them to either.
Printing on a custom Printrbot LC with natural ABS slic3r and PronterFace (older versions). The calibration is sub millimeter on the printer, and it looks like the print was 1mm short on both axes. I suppose I could modify the parameters.
What did you test the prints with?
