    I like the plan, and have been trying to think of a good print myself... but your link isn't working.

    Thanks, I fixed the link.

    First test.

    Nice. For the 5th test, given there's only 4 inputs, was it a single color and a soluble? Or a couple colors and soluble?

    For the 5th I plan on doing it twice.

    Test 1

    1.Input 1-Color A

        -For Base and S

    2.Input 2-Support

    Test 2

    1. Input 1-Color A

      -For Base

    2. Input 2- Color B

     -For 2

    3. Input 3- Support

    4. Input 4- Color 3

      -For 4 and S

     

    The goal will be to try and do all of these tests on both Canvas and Chroma. All tests so far are on Chroma.

    The test went well, as you can see there are artifacts laid down from the purple. Not sure if its retraction or something else, During the print after the purge from white to purple finished the head would go to the 4 for a second before it would go to the 2. As I said in the last post I am doing all of this with Chroma right now.

    Nice. I should try this, though I wonder what else this can be used for... such as reducing the size of the transition tower or something similar. I first need to stop messing with my printer before hand though.

    That will be a latter goal. Part of the reason why I started off with the pearl white as the base, it will let me see any issues. Especially when I go to reduce the tower.

    I'm giving test 1 a go and have the others lined up... (I'm using Slic3r PE + Chroma)

     

    And since you've mentioned "what's something like benchy that could be used as a test but still be nice to put on display", a thought came about of "a light house".

    Imagine having a light house where it gets more complex as you go up (and use more colors).

    • Test 1: Light house (input 1)
    • Test 2: Light house (input 1), light keeper's house (input 2)
    • Test 3: Light house (input 1), light keeper's house (input 2), railings/steps (input 3)
    • Test 4: Light house (input 1), light keeper's house (input 2), railings/steps (input 3), ornate details on the light house (input 4)
    • Test 5: Light house (input 1), overhang (input 1), supports for overhang (input 2/3/4, soluble)
    • Test 6: Light house (input 1), overhang (input 1), light keeper's house (input 2), supports for overhang (input 3/4, soluble)
    • Test 7: Light house (input 1), overhang (input 1), light keeper's house (input 2), railings/steps (input 3), supports for overhang (input 4, soluble)
    • Test 8: Light house (input 1), overhang (input 1), light keeper's house (input 2), railings/steps (input 3), ornate details on the light house (input 4), supports for overhang (input 4, soluble) <-- not sure about the Palette 2, but the Palette/Palette+ has the ability to swap inputs on the fly and I figure it could be an "advanced" test where once the supports are done, you swap in the "details" filament

    It could be interesting to make it a bit moduler so that, say, in the future, if there is a Palette (or other device) that can do 5, 6, 7,8. etc. colors... they can just keep adding on items with additional colors.

    And by "get come complex" the higher up you went, I mean how many splices and whatnot are needed as it goes up. Maybe at first it starts with just "make light house, now make supports" and eventually gets to "light house, moss, railing, step, brick, ..." and needs to switch often. Also could be a fun way to try different materials: transparent for windows, woodfill for steps, clay/normal plastic for light house, steelfill for railings (I've wanted to try this, but haven't gotten there)

    I'm reminded of https://www.myminifactory.com/object/3d-print-dragonstone-87204, https://www.myminifactory.com/object/3d-print-lighthouse-on-a-rock-26474, or https://www.myminifactory.com/object/3d-print-the-elder-lighthouse-71894 but not painted or printed as large "slide-over" pieces. (BTW, that person has some amazing prints)

    Lastly, I figure a light house would go well with a benchy ;)

    Only issue for me: I can only say the idea... my 3D modeling skills are not up to snuff to create something as elaborate as this. Maybe remix... after a couple weeks of work, but still. An idea.

    Vinnie,

    I love the idea. LIke you said the goal is to make a print that is "good" looking and functional at all levels. No matter how many or little inputs are used it is functional. 

    One thing I would want to keep int he design is the numbers. This way it lets somebody clearly demonstrate if they have issues with a particular drive an or color, in just a photo.

    So I finally got around to finishing the print (1-4, doing soluble tonight). They all turned out great. Only minor artifacts through the entire process.

    Again, I simply described the idea and how I would want it to work... but I'm not doing any modeling. You or whoever does it (if it ever happens) would have control over "does it have numbers" or not.

    I know this post is in the Palette 2/Palette 2 Pro section, but I used a Palette+, Prusa MK3, Slic3r PE, and Chroma

    My only regret right now (but I'll worry about this another time) is that I went with the "0.15mm Quality" preset which meant that prints took between 3-4+ hours to do.

    So I did print #1 which, because it's a single color, came out near perfect:

    Then onto print #2:

    So... already a problem (I mean, that is the goal of this, is it not?). Finished:

    So, the MK3 has a known "issue" (issue 602) and uses M221 to adjust extrusion multiplier across the whole machine for that specific print. For this print, that would be 95% multiplier. Chroma doesn't support M221, so I have Slic3r profiles for filaments (which is annoying) that adjust this by hand. I'm not sure where the issue is, but, I ended up with about 105% over extrusion.

    Followed "Perfecting Calibration" to adjust printer value and try again:

    Well... it looks much better on the underside, but the surface of both prints have the same bleeding. At a prior time, with my own attempt at a calibration model (looks like a tiny checkerboard), I adjusted the transition tower size. It worked for the checkerboard, but may not be working for this... I have since adjusted the tower transitions back to default and I'm trying one more time.

    Hoping it works out, because that's a lot of yellow filament... Note: I purposely chose yellow and blue as I knew it would be a "weak" color and a "strong" color.

    So I loved my +, when I bought the pro I thought I was going to be running both side by side and increasing my multi-colored print output. However, the pro does such a better job and is so much more reliable the + just sits now. 

    On the subject of the new print test, I am experimenting with trying to design something, I to lack any real modeling talent and am having to fumble my way through it.

    It's been tempting to buy a 2 or 2 Pro, but I've had a wacky history with 3D printers... long story short, I have a reliably functioning 3D printer as of Jan 2019. Then something weird happened mid Feb, and I just got it working again yesterday. In the mean time, I basically bought two Pro's worth of filament and another printer... I don't have that much disposable income to now go out and buy a Palette 2 or 2 Pro. Maybe in the future, but not now. So for now, the + does what I want.

    As for the model: cool, if you want me to test anything, let me know. I know the feeling about the modeling talent... I'm lucky to know how to modify a 3D model if I need to.
