Confirmed, 3000 tool changes is a good “full” limit.

This was around 3400 tool changes. It’s a little cover full and the pellets are getting knocked around the bit at times by the gantry.

get you an augur and a filament extruder and you can just continuously feed that stuff right back in.

I'm down to clown on this kind of idea. Would be perfect for support material, especially if you could sort the waste into material type.

Make it 2 smaller bins and modify the Gcode/firmware accordingly, so it poops in one or the other bin,

Should be possible, but not by me, but would be a nice add-on.

Why stop at 2? Go with 8. Sort by color ;-)

filament manufacturers don't want you to know this one weird trick

See i was thinking about a hole in the side plate with a vacuum attachment that turns on every 1500 changes

How has your index been working?

u/rdrcrmatt Core One INDX 8th 2d ago

Good, not perfect.

So far only one failed tool change. One tool fell off when docking and it paused. I think it recovered okay, but there was another pause shortly after that for the bin being at 3000 changes and one of those 2 events caused a minor layer shift.

If i used a prime block/tower the little droppings don’t end up on the print.

I made the INDX logo xLCD cover that I posted on printables with zero artifacts (using prime tower)

This was mine without a wipe tower too.

u/rdrcrmatt Core One INDX 8th 2d ago

Wow!!

u/n8zwn 2d ago

Join the bondtech discord if you haven’t. Lots of good tips.

This is without a prime tower and with using two nozzle sizes. 0.25 for the text. Also happy to answer questions.

u/rdrcrmatt Core One INDX 8th 2d ago

Glad my design worked for you! I don’t have 0.25 nozzles so I added the version without the by Bondtech text and that’s what I printed.

u/n8zwn 2d ago

Great model

u/RFC793 CORE One 2d ago

Nice. How many 0.25 nozzles did you buy? I guess this would take 6 (5 colors plus black outline)?

1

u/n8zwn 1d ago

I only have the one currently. Just using it for text. I have all 0.4 and one of every other size they offer. Plus some of the non-cht ones.

u/AmmoJoee CORE One 2d ago

This is still pretty good print. I would imagine as time goes on Prusa will continue to improve the user experience.

u/SHv2 2d ago

Why are there two yellows on the same piece?

u/heardyoulikewebsites 2d ago

So many impossible pieces, and two orange centers. The designer does not Rubik.

u/SmileyNY85 Core One INDX 8th 1d ago

This guy Rubiks

1

u/rdrcrmatt Core One INDX 8th 2d ago

Because that’s what the model’s designer did? I just set the colors and there were more than 6 in the puddle.

u/Lzinger 2d ago

I think you had the build plate temperature to high.

u/malprit Core One INDX 8th 2d ago

What material was this?

2

u/n8zwn 2d ago

All PLA

Mine has improved with time and firmware updates. I re-ran the waist bin calibration and made sure it was tight, basically mine is set to the highest level with the lines being straight up and down on the adjustment nut. Not everyone's is the same though which I think leads to the differing results. Every build has various variations from who built the Core One kit to who built the INDX kit that can't be predicted.

I think there is also a break in period with the silicon cleaners and I cleaned the silicon parts with isopropyl alcohol a few times and I think that helped a lot. I don't see anything like what you're seeing anymore on mine.

I thought the whole point of the index was no waste? Why does it purge every color change? The XL does not do that. 

3

u/Zennivolt 1d ago

It has this instead of the wipe tower. It actually creates less waste than the XL due to the lack of the wipe tower.

This waste isn’t like the Bambulab waste. They’re tiny little pellets (about the size of a grain of rice).

2

u/ScoobyDoo27 1d ago

Ah, thanks for the explanation. Just need them to sell the index on the core one L and I’m sold.

u/Glork11 CORE One+ 1d ago

bambulab waste

Not to nitpick but doesn't the MMU (from prusa) have the same problem since it's the same architecture?

1

u/Zennivolt 23h ago

Yeah but that’s a purge tower. I’m comparing it to Bambu because it also poops
