Dremelizing Cura

Someone has work-in-progress configs on Github to get the current version of Cura to work with the Dremel 3D45. The basic functionality is there, but there’s no network or camera support, and the output quality is… poor (way too much retraction and stringing, and big gaps in pin-like elements). I’m happy with PrusaSlicer for now, but it’s nice to see someone working on more options.

Incidentally, I took a look at how Dremel got the network printing and webcam support into their customized old version of Cura. They heavily edited the UltiMaker 3 script to use their API, but it looks like they never got any kind of network discovery working. It would be faster to write a new Python plugin than to try to modify the current version of the UM3 code, especially since I’ve already got a working Bash script.

Quality update!

To no surprise, replacing the 6.5mm retraction with the 2-3mm that Dremel had in their version of Cura significantly improved the results. I can now do head-to-head comparisons between Cura 4.8 and PrusaSlicer 2.3, to decide which one handles specific parts better.

For my babydai koma, I find the overhang+supports quality unacceptable in both, so I’ve added some 0.5mm-wide manual supports to the model that can be easily snapped off. This forces both slicers to treat them as bridges, which significantly improves the results. And cuts the print time and filament use a bit.
