Shrink the XL 25% and call it the MK4  

RE: Shrink the XL 25% and call it the MK4

You should only call it i3 MK4 if there is a clean upgrade path from MK3.

Otherwise, it would be a completely new machine and should not be allowed to inherit the name.

RE: Shrink the XL 25% and call it the MK4

I think it would be interesting to make it so that you could use the XL heads on the new i3.  Maybe have it be able to use two heads at least, or really just one, but make it so that it is swappable between prints.  That way you get all the new extruder and hot end tech.  A major issue I have with the MK3 is that anytime you want to do work on the hot-end/extruder, there is a lot of work to do.  Being able to take it off and do maintenance and repairs while using another ‘head’ would be great.

RE: Shrink the XL 25% and call it the MK4

@lichtjaeger How much change is needed and permitted to call it a MK4 ?
Change too little (eg only going 32bit) is nice but not enough insentive to upgrade.
Changing the dimensions also maybe too much and results in a completely new machine.
I would love a bigger size xy core machine, but without the cost of the XL, 2000+ is just too much for a hobby machine.
Could one water down the XL even more without changing the dimensions (eg just 1 heated bed with no heatzones) ?
It would make it more affordable and still have an upgrade path to the XL...

Cheerio,

RE: Shrink the XL 25% and call it the MK4

I agree that if there's no upgrade path then it won't be a MK4, maybe just the heat bed and Nextruder? Core XY and linear rails would entail changing almost the whole printer. Having the Nextruder with no need for first layer calibration would be great

RE: Shrink the XL 25% and call it the MK4

I think any upgrade would have to leave the basic structure in place.  Maybe swap the shafts for linear rails, but only as an option.  Using the new head and electronics and segmented bed would be interesting.   An MMU3 would be appreciated also.  If the electronics are more powerful, a motor and drive for each filament would really be a way to simplify and make the filament changes more robust.

RE: Shrink the XL 25% and call it the MK4

I'd be happy if the Mk4 eventually came out with an upgraded version of the Mini's 32-bit board (and screen) as well as the Nextruder. I'd expect all the Mk3's and the Mini's features to be included, as well as Prusa Link embedded in the firmware. That'd be good enough for me.

Thank you MileHigh3Der!

I agree with you!

<< ... Using the new head [so you can easily change the nose]
and electronics [but the previous one is not so bad...]
And segmented bed [with a bigger bed than the mk3s].

An MMU3 [new !] would also be appreciated. ... a motor and drive for each filament would really make filament changes simpler and more robust.>>

I also ask for a housing [for asa, abs and others].

Who'd want to pay $2-3k for a slightly smaller XL? 

RE: Shrink the XL 25% and call it the MK4

I would. I don't need that much space for printing, the MK3S+ is enough for me. But I really want a multiple toolhead option. This and the CoreXY build are the only things that make me want an XL. A smaller slightly less expensive version would be a dream come true.

RE: Shrink the XL 25% and call it the MK4

Wouldn’t i4 MK1 be a more appropriate name?

RE:

The problem with adding an extra head to the Mk3 upgrade is that you will lose print width.  That is unless they add a tool changer.
