Hi everyone. I've started printing my dungeon floor tiles and they've been coming out with globs of PLA on certain areas of the tile. They sort of look like pools or scabs. The image is below the cura settings. Does anyone know how to avoid this? I've turned off ironing and the same thing happens.
Here's my setup:
Creality Ender 3 V2
CR Touch autobed leveler
eSUN PLA+ Black 1kg
Settings Cura 5.0: Standard Quality-Layer height: 0.2 mm
-Wall thickness: 0.8 mm
-Wall line count: 2
-Horizontal expansion: 0
-Top/bottom thickness: 0.8 mm
-Top Thickness: 0.8 mm
-Top layers: 4
-Bottom thickness: 0.8 mm
-Bottom layers: 4
-Infill: 20%
-Infill pattern: cubic
-Printing temperature: 210 celsius
-Build plate temp: 50 celsius
-Print Speed: 50 mm/s
-Retraction enabled
-Ironing enabled
-Pattern: Zig Zag
-Line spacing: 0.1 mm
-Ironing flow: 10%
-Ironing inset: 0.38
-Ironing speed: 16.666
From our website, you can see the same difference in layer height that you're referring to as "blobs" on the hexes in the lower left tile pieces. It comes down to layer height and the fact that the tile itself has slightly raised sections in its design, which manifest themselves thusly.
Hi. I can confirm that even Jeff and I have mixed results in terms of the tops of the dungeon hexes. I use the ‘standard’ .2 Cura profile and these settings vary between giving great, smooth, crisp results and then blobs/stripes across the top. I am yet to work out exactly what it takes to get consistent results but it seems to be to do with how the printer is running/bed level rather than the slicer settings, because as I mention, I have achieved excellent results with the standard Cura profile. I have never been too worried about it though to be honest, I find once painted the artefacting across the top just makes it look dungeon-y and helps individualise what would otherwise be four repeating patterns.
