13.06.4 'project planner' strange behavior

Recommended Posts

Posted · 13.06.4 'project planner' strange behavior

Hello,

A few days ago, I started using a trick with brim and rotating models to get fairly thin / odd shaped models (belt buckle ornaments with no obvious good point to set on the build plane) to print without support. I tilt the model back 45 degrees, sink a mm or so into the build plate, and run a brim. It's been working really well.

I just started a print job with two objects on the BP. These parts required some rotating. I think I did a 90 about X, 30 about Y, then a 45 about X again. Rather than building the parts one at a time in serial, the parts are being printed in parallel with all of the stringing between.

So, I sat back down at the computer and tried moving the models around to see if anything would change. The simulated tool path showed that no matter where I moved the models, it would continue to calculate a parallel tool path.

I deleted both models and tried again. With the models left in their as-dropped orientation with no rotation, everything works normally (models built one at a time).

So then I went and rotated the models into the orientation I wanted outside of cura and saved the stls in the new orientation. Reloaded into Cura and got the same result as when I rotated from within Cura (parallel printing).

Any thoughts on why this is happening?

Here are some screenshots of the simulated tool path and the first few lines of the code. If its helpful, I can post more of the code.

Go to "file" "preferences". Set the 5 variables in the bottom left to the recommended settings.

If gantry is 0 (or smaller than your object) it will print them all at the same time (parallel) so that is the most critical dimension. Just hover over each one and type in the default values for ultimaker.

Yes, I suspect that your new orientation is making part of the object stuck up above the gantry height, so Cura gives up and prints them in parallel.

Thanks guys. With the rotation, the z on the one part was 66.

I should have been able to figure that one out on my own. Darn sleep deprivation.

:oops:
