Hi guys
I upgraded to SkeleStruder, Taurus axis and more.
I took before and after pictures and made sliders to compare them, for example like this: https://cdn.knightlab.com/libs/juxtapose/latest/embed/index.html?uid=e960ff20-7fb2-11e9-8804-0edaf8f81e27 (Might take a while to load)
I documented everything here: https://lord-carlos.github.io/mk3-upgrade/
TL;DR: I can't see a difference, except overhangs.
Enjoy 🙂

Thankyou for the detailed writeup. 👍
I am in the process of creating a Skelestruder
My understanding is that the whole point is lighter weight to allow increased print speeds and also better handling of flexible filament. Maybe try some high speed flex tests? 😀

No problem.
I did try to make a speed test, but got hindered by my inexperience. I printed some stuff with 120 mm/s.
As for TPU: I can't quickly switch between stock and skele any more a test would not be very effective. For best TPU experience with skele you need the metal brush thingy, which I don't have.
But it looks like you are in the perfect position to make such a test 😛

Also no heat creep from the bondtech gears as the drive is now indirect and due to the increase in ratio (3.5 on mine, seems most common) there is less artifacting from any notching in the extruder motor linearity.
(Basically on a stepper motor as the motor moves from magnetic pole to magnetic pole you may not get perfectly linear movement, this can show up as micro waves where slightly more or less material is extruded, the ratio in effect reduces this effect by 3.5 times if you know what I mean).
Skelestruder makes filament cold pulls easy, no need to unscrew anything, just lift a part whilst pulling the filament.
Cooling duct design allows you to see the nozzle as well as improved cooling compared to stock so you can get better overhangs.
If you have a Mk3 with the optical filament sensor, you can use a bearing as an indirect filament motion detector so it works with a wider range of filaments.
Also I learnt more about 3d printing making one of these, which is always good.
Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.

Not 100% sure, but I think this picture might show it:
Top is skele, buttom is stock. You can see a pattern. Though I think some Greg3d on twitter has some firmware magic that also removes that from stock.

There is definitely a surface difference in that photo above.
I look forward to giving mine a try soon (just waiting on some parts)
