Indeed a plugin where you select the layer, angle, repetitions, extrusion, line width, speed and z offset (for future stuff) should work just fine. And if it could have his own prime tower even better.
A prime/wipe would be really nice. It could 'sand over it' to clean the nozzle before sanding, then do the sanding & then go back to the prime/wipe tower to extrude and get the flow ready back to print.
Edited by Guest"Sanding" can be a top pattern ?
Well IMO the sanding works nice with just infill angle, perimeters do work, but because the 100mm/s speed, sometimes it leaves weird marks from the speed yerk, and if you go below 70mm/s you can get weird effects on weak spots (because of reheating the pla just printed). It could be nice to leave that open, to allow perimeters, or only infill and selectable (or automagical) sanding angle.
Just found out a faster, and easier way to force S3D to do the sanding process after the real print process.
If the real print it's done at 0.2000 layer height, then make the Sanding process have 0.2001 layer height.
This way you don't need to copy/pste the process until you get the right order.
About speed jerk: Could you make the sanding area larger, so that the jerk happens outside of your part?
I like this idea. It is remarkably simple (from a slicer point of view: redo the top layer with different settings and direction), but it is remarkably effective. Definitely worth developing further.

Indeed, the side effect is that without a prime tower, the small bits of filament left to be extruded make some small marks (they don't leave the hotend unless there's a hole to fall into). So to avoid this the only way I see it's to increase the difficulty (and print time) making a prime tower (that should have gaps), making the sand over the prime tower to clean the parts left of filament, and then moving to sanding with a fully clean nozze. Then ofc it will need to prime the extrusion before continuing.
@neotko you are amazing ! I would never have thought of something like this!
The results are really cool on the images you posted, and i love the name
To avoid the prime tower to clean the nozzle there could be some kind of wiper thing (@foerstrum) where you would clean it with a special gcode just before neosanding
Yeah that would be perfect indeed, most of the time the first perimeter printed just after gets a slight underextrusion, fans help to contain the stuff on the nozzle, as soon you drop the fans the print can be a mess with weird effects. I think for weak fans it might be problematic.
@DidierKlein, @foerstrum won't work, try foehnsturm
I already made some test prints using the 2nd head for sanding. But it will require some more. I'm still a beginner here (it took me 5 prints to realize that, as neosanding needs something to sand, it doesn't work well with toplayers with almost invisible but existing underextrusion)
Yeah I should have mention that I suppose. It took me a great deal of time to calibrate my esteps perfectly and until I used the ruby nozzle from Anders I wasn't able to 'see' the underextrusion ratio and fine tune it. Also it did help to solve the hard part of my prints that's the small letters. It was quite a ride. (that noone did seem to read or comment XD) the adventure it's on this post

If you can't see the underextrusion and only use the effect for top layers, you can do this (it works, but with big flat areas you might get the nozzle with residue so I didn't publish it)
On the gcode of the sanding process change the offset so it forces the sanding effect to occur -0.02 Z (the minimum resolution of the z stepper), this will flatten the print, it also can add weird effects and drop down objects if they are too thin or not well stick to bed.

Oops i wasn't sure of the spelling and was too lazy to search for your name sorry about that
But somehow you still got the message
Thats looks sexy as hell! Do you plan make some video tutoruals on YouTube about printing with S3D on UM2/UM2+? Or recommend good channels for learning?

I've got this feeling that neosanding will become a 3dprinting clasic !!! <3

CURA dev, please add "neosanding" in "Special Modes" section NOW !

insanely cool idea, this should definitely be added to Cura as an advanced feature if possible
S3S needs competition
Im also hoping to see adaptive layerheights someday in slicers.
This have been done in cnc machining software for years, where you dont type in z step amount for contour milling, you type in max allowed step and software adapts cuts to what angle its milling. (imagine printing a 50mm ball, in the middle where the diameter is bigger a 0.2 layerheight is fine, but at the top it will look coarse and ugly)
