This XL Benchy on the Prusa XL is over 16' long!

Printing the largest benchy possible on a Prusa XL printer is 16.5" long!

It's nice to see your channel grow so quickly😊 you're still the only one uploading actual test footage of this printer!

Thanks for filming this. Its great to see large prints run off this as it was intended! I’m still waiting for my preorder email for my XL - in the meantime I’m living my XL printing through you!

A Benchy is designed for its original size. At such massive dimensions bridges and also overhangs are so wide that noticeable sagging can be expected. You would either have to add supports or try if much slower briding speeds at max cooling can help already sufficiently.

Holy guacamole, this is the TITANIC of all Benchies⚓😱👍

For what it is, the print looks fantastic. The layer shift was inevitable, as you said, due to the yanking on the hotend... something shifted slightly. And the overhangs were designed for an original size benchy, so they're not all that bad considering how large you went. Well done!

[crazybird]

That's massive! From what I'm seeing, that's a nice printer. I've also made the mistake of telling the printer that the filament came out correctly when it had not. Bit frightening to feel it stuck in there. It makes sense that there was some sagging, since the overhangs are very large. I would, personally, do a single color print if I were to do a large benchy like that, to avoid the rainbow issue you had. Thank you for being one of the first to talk about this machine!

That’s insane, I’m actually impressed how well it did with all the overhangs etc at that size!

[wadewoehrmann]

the shift can be seen as you pull the filament. Re run the test with the tweaks needed and perhaps just a little less infill so it will print with one roll???

[cversion]

Great test! Just found your channel and look forward to learning more about printing. Don't think I'd ever try printing a benchy so big, but cool to watch. :D

[karmakh]

I would not print one, but it's very cool to see someone else try it :D

[somewindowcleaning]

These videos are amazing thank you for putting em up

[xDDDx]

Like this funny stuff you did and yes, the layer shift is just because you are not friendly to your extruder at all :D
The sagging is pretty good compared to the large distanziert at this print! Overall good quality.

Are there not command buttons on the Nextruder that you could programme? Normally in this scenario if the extruder still has a grip on the filament then you'd want to reverse the extruder to release it. Does the firmware on the screen offer any options that would allow you to do this? Appreciate this is a new printer.

Failing that, opening the idler door if there is such a thing on the XL should unlock the extruder tension and allow you to release the filament by hand? Less moving the toolhead when you have it paused will result in better prints unless it rehomes X and Y after you have replaced the filament (unusual in Prusas?). The printer wouldn't know where the X and Y axis was if you moved it by hand during a pause.

The stuck filament is an interesting take on a common hardship. So this happens on my Mini when the filament unloads (waiting for a change overnight) and it kinda gets stuck in the tube after the extruder gears and cools. In my case just a little force pulls it out pretty easy because the gears are *right there* where you load the filament. In the XL's case the extruder is miles away from the loading tube...so you're only choice for any reasonable direct force is to remove the tube like you did. This kind of makes me realize that really sucks with the XL and something that's not a big deal for my Mini, will be a bigger deal (and potentially cause the layer shift problem) for the XL which is supposed to make life easier. Hm.

These are the small things in the menu that Prusa should really change. That already gets on my nerves with the MK3s+.
Thanks for this nice Video.

[fwiffok]

It's possible that in removing the filament you moved the head, even a little. This could be a nice bug file, since the head must have enough current to avoid such an unwanted movement

[Glacialsss]

It is cool to see you test these things, thanks for this content. Would love to see a bust of some sort.

[snuups]

Yay. You are now officially insane. I won't print a benchy but I will print a Lioness as soon my XL arrives.

[mchless]

Great video, just subscribed! Looking foward to see what you make next :)

[scifimodelshop]

I hope down the road some tweaks can be made to the printer for fast printing times after all it is a core XY
