Hi everyone,
I am having trouble with these bumps appearing during the slicing of my part. And whilst not a perfect replica, the bumps appear on the print as well.
First photo shows the slice preview, and the 3D-printed result. This is an issue as this cog needs to mesh with a reciprocal part, and the bumps stop it from happening.
I was fortunate enough to find an old UFP file where I had 9 of these cogs laid out, and you can see no bumps are present. This printed perfectly and got me out of a pickle, but I am keen to figure out the problem, as it shouldn't be happening.
The second pic shows the UFP file with the correct slicing.
I have also attached the STL and the old (working) UFP file if that helps.
I think this is an issue with the slicing as the problem is present there, and also the print.
Printer: Ultimaker 2+ Connect
Filament: Ultimaker Tough PLA
0.15mm layers
Speed: 40.0mm/s
Enable retraction ticked
Cura V5.3.0
I have even gone back and installed older versions of Cura to see if that was the issue but unfortunately not.
This has got me stumped, and I would be grateful for help solving this.
Thanks,
Shaun
