    *TO CLARIFY:*
    What makes this huge boost to the print quality is printing the OUTER WALL before the adjacent INNER WALL is printed.
    That is why I called the Inner/Outer/Inner wall ordering option "printing outer wall first" as it does exactly that. Hopefully, that clarifies things. I know it can be quite confusing.
    *So TLDR:*
    Inner/Outer = IW first
    Outer/Inner = OW first
    Inner/Outer/Inner = OW first

    This is the first video whose title contains the tired, old "GAME-CHANGER" claim that actually turned out to be a game-changer for me. Printing the outside walls first made a MASSIVE difference in the quality of my prints. I've been living with semi-OK prints for literally 3 years...can't believe I've gone this long without knowing about this setting. Why isn't it on by default in all slicers?
    Edit to add, after another print: I seriously can't believe the difference this made. My print looks almost injection-molded, for cryin' out loud! And I'm running it on my trusty old Ender-3 V2. Unbelievable!! Thanks for this tip!

I had the same lines on prints from my Prusa but much less visible, maybe due to lower print speeds.

      Cura made it default for a while but then reverted it, because they have lots of bad defaults that cause missing extrusion after unretract, especially on bowden printers, and they want to hide that on inner perimeter rather than showing it on outer. Despite it harming part integrity either way. 🤦

    One likely reason is that curling and warping are caused by outer layers not having sufficient time to cool combined with the contraction of inner layers as they cool pull in on the outer filament. So by printing an outer wall first, you’re giving the outer layer the most time to cool so that it can be already solidified by the time the printer gets around to it. I legitimately never thought of it like that.

    • @Smokinjoewhite

  • @802Garage
    @802Garage 8 місяців тому +24

    I had great results with these settings as well, though admittedly with limited testing. Most of the improvements make sense. I realized one reason the overhangs being as good or even improving may make sense while watching for video. First of all, the filament has more room to expand and sit on top of the previous layer, since it won't hit the inner wall and then have to squish outward over the side, which could cause a drooping overhang. Sure, you may think because clinging to the inner wall would keep the filament from falling outward that it would help, but the volume of filament extruded all has to go somewhere, so outward is the remaining direction if the inner wall is present. The other reason I think it may help is that not having an inner wall means the outer wall extrusion can be cooled from both sides, it even has a little channel of air flowing past it, and it isn't being kept warm by the previously printed inner wall. I would suspect the added cooling is a much larger factor than residual heat from an inner wall, but the amount the latter varies would depend on the print.
    I wonder how much outer wall appearance would vary with line width as well, especially with overhangs. Also counterintuitive, but wider layer widths can actually give better overhangs because it insets the outer wall more on the previous layer, meaning the center of the nozzle is less in free air when extruding. Anyways, very interesting tests and results! I do think I saw a slight improvement in your tests with the precise wall setting on, as especially the lower ridge on your far right test print was smoother. Hard to say not holding it though. A combo of outer wall first, precise wall, good cooling, and perhaps even wider than nozzle width layers could be the ultimate combo. Beyond that, precise extrusion is so important, as you repeatedly mentioned. This seems to be the Achilles heel of the K1 series, for example. Once you get extrusion dialed in, testing all of the other settings reveals a lot.

    • @PrintingPerspective

      Yeah, there can be so many things why we can see this happening that I just gave up on trying to fully understand why. The more I dive into 3D printing and how things affect stuff the more I am starting to see that assumptions why are quite often not correct.
      The K1 series extruder is armchair engineering at its finest lol, as the drive gears are only supported from one side, with the filament inside, those gears bend out of square and flop and wobble even more, a truly bad design. :/

    I'm testing this now and hoping for great improvements to dimensional accuracy for my Clickfinity Refined plates. One note: the description of the travel distance threshold is not clear at all, and since it's the most replayed part of the video I'm not the only one.
    I read around and from what I can tell from your video is that you have a travel distance threshold of 1mm and a Z hop type of Spiral. This causes Z-height movements when moving to another wall > 1mm away, slowing your print times (and probably heating up the filament more during that S hop time, causing dimensional issues). You recommend increasing the default to something like 2mm which reduced your print times. But this is only true because you have a Spiral Z hop type vs Slope, which combines Z movements with XY movements to reduce stringing.
    For me-Bambu Labs P1S w/0.6mm E3D ObXidian nozzle-the default value (under Printer Settings » Extruder » Retraction » Travel distance threshold) was 3mm with a Z Hop Type of Auto (aka Slope), so this is not applicable to me. Z Hop defines how the print head combines Z movements alongside XY movements. Keep in mind that some users are seeing scraping when the travel distance threshold is > 0mm. If this is the case then Z Hop Type to Normal might help at the cost of longer print times.

    i don't understand why you don't experience any issues with overhangs. try circular objects with steep overhangs inside like inner threads. there "should" be adhesion problems due to no inner wall where the outer wall can be attached to to help compensate that there is almost no wall below where it can be printed on. that's the resulting famous spider net where there are straight lines in mid air instead of circles.

      I haven't watched this full video yet, but I thought I would check the comments for people having issues with overhangs using this setting. I usually always print with 3 walls and heard that doing outer inner or inner, outer, inner, is the best for dimensional accuracy and how it looks on the outside and for the most part that's true. But depending on the model, I've definitely noticed an issue with curved surfaces where there is even a slight overhang or angled surface. I eventually gave up on it and only use it when I know it's a straight surface and I truly want the accuracy.

      Overhangs are actually better IME with outer first, at least as long aa you have proper cooling. When there's very little material below to bond to, the surface tension effects instead pull the outer to the inner perimeter if it's already there and make it go in the wrong place then curl because the extruded length is wrong for where it goes.

      For layer width and layer height I believe it's all about increasing the amount of overlap between one layer and the next.
      Larger line widths will overlap the previous layer a little more, improving adhesion and therefore overhang quality
      Similarly as you reduce the layer height the amount by which the next layer on an overhang is moved out by decreases (because there are more layers and so a finer "grain" to the stepping out), which increases the overlap between layers, improving adhesion and the overhang quality.

    Inner out inner is the best but remember overhangs will perform worse, so you need to lower the layer height to help compensate. Also Orca and Bambu slicer do a crap job of converting arcs when using arachne, so run it through arc welder afterwards.

  • @RexAnothership
    @RexAnothership 7 місяців тому

    For tight tolerance or for quality surface I always use outer wall first but depending on the finish I need 0.4mm outer wall with 0.07 layer height and 0.7mm infill with 0.2mm layer height to make up for slower perimeter speed. This works great for overhangs and surface finish as it prints 3 layers of outer wall before 1 pass of the infill. This is done with a 0.6mm nozzle.

      It was 150/175mm/s speed, not too fast but not too slow either. You won't as the reason why we see such a huge improvement by printing the outer wall before the adjacent inner one is printed is because then the outer wall extrusion is not affected by the inner wall.

    Some of my best prints came off a Kossel Mini I built way back in 2014 that had a bearing for idler vs driven hobbed idler gear. That said, I'm not a big fan of concave hobbed drive gear or idler, because the filament can walk up the sides of the idler and/or hobbed gear which essentially changes the gear ratio, think CVT transmission and the filament is the belt.

    Outer walls first was important for me, because it improved accuracy and stopped hopes from printing undersized... and it also ended up increasing print quality by a good amount. I use only a mostly factory Ender 3 and get extremely good quality prints from it. I temporarily upgraded the hot end with a Micro Swiss, but for some reason I just can't get it to work right. I have constant partial-clogging and poor quality prints that break easily, because some layers were printed with partial clogs (and the layers are thin walls). I have to go back to the original hot end until I can find a better replacement, but I have no idea what to buy. I don't have a lot of money, but I just want to be able to print CF Nylon. I probably should have just gone with an all metal heat brake, but I was told that the Micro Swiss was the way to go. Also have a Sprite Extruder (not installed) that would be nice to be able to use... but the important thing is being able to print good quality with PLA+ and CF Nylon. Don't care too much about anything else, although higher speed would be nice.

    It uses a Hall effect sensor to measure filament diameter and Klipper compensates for it.
    And you know what I found out today? The Q1 pro has a filament runout sensor on the extruder which is not a simple switch but actually a Hall filament width sensor! Just it's not used as diameter sensor, only as runout.
    Maybe you could try to calibrate it and enable it to see how it performs, if it helps or not. The author of the article writes that with that sensor he basically doesn't need to fine tune the extrusion multiplier for each filament, they end up all at about the same value.

    I've long had the theory that printing outside perimeters first would result in a better finish, as you could print & set the outside perfectly without any unwanted influence from inside layers. Yet, in my 8+ years of printing I've never actually tried it. I just assumed the pro's knew better, perhaps printing from inside to outside provided structural benefits that I couldn't understand, and of course I figured overhangs would be better inside-out. Just this week I've been fighting outer wall finish issues where inside structures show up as ghosted outlines on the outside, and while I again thought about trying this setting, I was too hesitant.
