Pieces not printing perfectly square

[morenoa0922 0]

Hi --

I am printing these pieces that will be assembled later. They are supposed to be perfectly squared (modeled as a cube in Openscad).

When I put them together, there's an open angle (See pictures) I don't know why they don't print as squares.

Any idea on how to fix this?

The two rods that pass through the print head are not perpendicular. That is why the print isn't perfectly square. It's easy to adjust them - loosen the setscrew on one of the 4 pulleys and make the crooked axis straight again. Push the head around to the 4 sides to see where things aren't quite square.

But I don't think you can ever get it perfectly square. So you need to print these 4 parts in the exact same orientation such that if one is a paralellogram where one corner is 89 degrees instead of 90 then the same corner will be 89 on all 4 parts and they will meet up nicely with no gaps.

Or maybe the error is only .5 degree. Or 0.1 degree. But whatever the error is you want it consistent to get rid of these gaps.
