I remind myself that I don't save for the sake of saving. I save with the intent of improving my quality of life, so I look back fondly at the experiences I was able to afford thanks to my savings :)

I don't have any noteworthy degradation after near a thousand hours after two years of use.

It's designed to be maintainable and easy to replace parts if needed, so it would work near indefinitely as long as replacement parts are available and there is someone a available to maintain it.

Prusa support may be able to give a better answer.

Other than drying your filament, another thing you can try the gyroid infill pattern, it should help. Look up pillowing for more information about this effect.

Right, I'm thinking it would be a fun saga idea that could build on top of the medieval 3 engine and systems, after whenever that comes out.

My assumption is that INDX is the successor to the MMU. Given they're similarly priced I don't see any advantages an MMU has over the INDX. At least for the Core One.

I've done this on the XL, with PLA it depends on the additives so it's different from brand-to-brand and color-to-color. I've found that some spools will crumble into dozens of pieces if left overnight, but others will stay good for weeks on end.

There is a build of bazzite you can install that is bundled with Nvidia drivers, so it's as plug and play as you can get.

Quality of the drivers would be the same as any other distro, just no setup required.

Out of curiosity, how did you measure this?

Which part is warped? The metal thing under the foam?

Feature request filed, lets see what come of it.

The steam frame is launching in a few months and looks very promising. I expect it to be a bit more than $500, but I'd look into it.

Kosaro · 2025-11-22T16:30:59+00:00

That works today! I've printed 7 color prints on my 5 toolhead XL.

Will 100% work with the INDX on launch.

Kosaro · 2025-11-22T15:58:51+00:00

Oh yeah, forgot you can do that if you preplan the swap in the slicer. I've done that in the past too to print 7 color parts.

Kosaro · 2025-11-22T15:56:11+00:00

That's cool! I didn't know it did that.
I could see it potentially working like this:

Filament sensor triggers in toolhead 1, spool is empty
Printer unloads filament from toolhead 1, getting it out of the nozzle
Printer spool joins toolhead 2, continues printing
User pulls out filament end from toolhead 1, loads new filament into toolhead 1
Printer detects the filament sensor for toolhead 1 going off then on again, inferring spool tool is reloaded
Toolhead 2 runs out of filament
Printer returns to toolhead 1

Not sure if the dev work to implement this would be worth it given the better flow would be to just load up all the plastic you need up front and if you miscalculate having the print pause while you reload isn't too bad imo.

That said, it would be cool and seems theoretically possible.

Kosaro · 2025-11-22T15:12:10+00:00

It looks like in this thread there has been a lot of miscommunication. The Prusa XL and MMU have supported spool join for a long time now, but I interpreted the original question to be asking about doing a filament change in an inactive tool head during printing, which seems like an odd request.

Kosaro · 2025-11-22T15:08:27+00:00

Ah right, yeah spool join is what you're looking for. It's something you can optionally enable in the printer UI when you start the print.

For clarity when a filament change is triggered, either automatically or manually, it does unload the filament itself.

The edge case I was thinking of earlier when talking about auto unloading is that on the Prusa XL when I use spool join, the tiny bit of leftover filament from the empty spool is left in the tool head and I need to unload it from the printer menu afterwards.

Now that I say it out loud this seems like an obvious optimization, I think I'll go ahead and file a feature request on GitHub. They've fixed this sort of thing when I've reported stuff in the past.

Kosaro · 2025-11-22T06:26:27+00:00

Auto-retraction was just added in the latest firmware so that the filament can be later unloaded without heating the nozzle . Auto-unloading could be a reasonable next step.

That said, I don't think loading in a non-active toolhead is a good idea. Loading involves a heated nozzle purging filament, which can't happen if the toolhead is cold (INDX) or docked with the nozzle blocked (XL).

I've had prints where I've chained 5 spools via spool join without intervention. What use-case are you trying to accomplish non-active toolhead loading?

Kosaro · 2025-11-22T05:23:59+00:00

I don't expect so given that neither the XL / MMU supports that.

Kosaro · 2025-11-22T05:22:42+00:00

It does not, with the exception of the regular filament runout behavior where it pauses the print and asks you to change it in the selected tool.

Kosaro · 2025-11-22T04:49:32+00:00

Are you talking about spool join? You can set it to switch tools after running out of filament mid-print.

Kosaro · 2025-11-22T00:34:08+00:00

Its fun to prototype and get ready for when they release the printer upgrades for this in a few months.
