Surface detail P6*6 camera body (Click to view larger image on Flickr)
I must fix the surface defects in this print. I’m am optimistically putting this in “Software”, hoping there is a bit I can twiddle somewhere to eradicate this issue.
Lulzbot Taz 4 with default settings, Slic3r 1.0.1 (? latest). duplicated with two different mfr’s filaments, and at different vertical resolutions, also at 50% and 65% infill. It appears to be an oscillation or a thermal effect in the extruded plastic after printing faux knurled texture from left to right. It is actually tiny holes in the surface. I see a little bit of wobble after direction changes, but this is so much worse than that, and the the bottom layers (without the knurling) show similar irregularities. Notably, the knurled texture prints flawlessly. The smartphone photo could be better, and I may append a higher res image tomorrow.
Not really sure what is causing this. It’s on both sides of the printed object after printing the radius in a clockwise direction. Does not occur on inside surfaces. Have tried printing exterior perimeters first and last, same results. Thinking about speed and/or acceleration settings next.
The slic3r output is just straight lines on the perimeter at the points where this occurs. Nothing funny there.
Too hot? Too cold? Too fast? Something too loose? I’ll keep guessing and experimenting, but any direction would be helpful.
PS sorry about the link to the pic - Flickr made it harder to link to pix, even your own. Any advice welcome.
