So I was able to get one (somewhat) successful print on my Hyrel using Cura! I dialed in the same settings I had in Slic3r and the same prime/unprime settings! However, I had to use a slightly higher feedrate and a slightly higher pulses per nl value than normally required when slicing with Slic3r due to the different movement patterns of Cura. That was a very minor adjustment though. For my test piece, I used the very popular 3d Benchy (the jolly 3d printing torture test) (http://www.thingiverse.com/thing:763622See) the below series of pictures for a detail of my results:
The left picture is benchy sliced with Cura, and the right picture is Benchy sliced with Slic3r. You can see a few things right off the bat! Namely, The Cura version has a more uniform surface finish and a bit more of a shine to it. Also, the surface definition appears dramatically enhanced with Cura!
I kept all the settings as close to the same as I could between slic3r and cura to get a true comparison.
Here’s an overall view (again with Cura on the left and Slic3r on the right):
There was only one small problem with the Cura version: the layer shift. That happened because I had the speeds set a little too high in Cura. If you try to print too fast on Hyrel printers, the stepper motors skip and cause layer shift, so I have since dialed the speeds down. I’ll be posting an updated benchy soon!
