I know there's already a bunch of different overhang tests, but I hadn't seen one that suited me, so I made yet another. This part goes from 40 degrees to 80 on a single surface in a simple, compact part. (updated - I made the numbers larger so they'll show in thicker layer builds and flipped them o...

The arm's not metal, but should still work as desired.

Tried running Taulman PCTPE tonight. Gave up on the new gear and went back to the old. Filament kept slipping. Diameter varies quite a lot on this stuff. I drilled out the extruder drive housing to 2mm just to be sure the filament wasn't just getting stuck.

This web site will take a 5000x5000 raster image and convert it to several different vector formats including DXF.
I used it recently to create a file for a vinyl cutter and it worked well.

sal I changed none of that at all. all that stuff is pretty much set in s3d when I generate the gcode file so I don't thing the octoprint profile even comes into play. I just leave the generic reprap one in place. I've been changing the nozzle diameter in the profile when I change nozzles on the pr...

In my case simply removing the fan guard made the fan so much quieter that I decided not to go to the trouble of replacing it I learned this when I was building a quiet computer for my recording studio a few years back - getting the grill away from the fan blades makes a big difference in the noise...

I use PTC Creo (aka Pro/ENGINEER) via the day job.

So far I'm finding the new gear to be touchier about the pressure adjustment - needing attention when changing materials - and I haven't seen any real benefit.

As I said above, my main goal was to maintain cooling with a lower RPM fan - not to increase CFM.
