A "calibration cube" of my design.

A “calibration cube” of my design. Sliced with Slic3r 1.2.6 (experimental), each step measures 0.2mm larger than the 10mm increments of each step. I know it’s not my printer because Cura g-code produces much better dimensional accuracy. Might checkout a stable branch of Slic3r or switch to Cura.

I’ve been having difficulty getting good fits with my OpenRC Swift prints. Debugging… I’m happy there’s nothing wrong with the printer.

Check if there is bug report for this or fill a new one, please, so its fixed and more people dont have to suffer

Can you share that shape?

Andre_Roy · March 17, 2015, 2:38pm

Yes I could share. You want? I will check the bug reports or fill one out.

Andre_Roy · March 17, 2015, 2:59pm

This evening after work, I’ll post the STL.

Slic3r 1.2.6 is otherwise really good! I’m excited for the new features to be release in a stable branch.

Tried Slic3r 1.1.7 (Stable). Getting good dimensional accuracy there.

Thanks André

ah, that’s just a leathery fabric I used to take a nice picture. I actually printed on a heated aluminum plate with painters tape on top.

Turns out there’s a new feature called XY Compensation that one uses to tune print accuracy. Works great.
