It's June 2nd....

And I'd like to know if orders are already being processed, at least for the people who bought the first edition, and if the pre-order status has been updated for anyone in the first batch.

Let the Clone Wars begin

Well, I did not expect it to happen this fast, but unless I am misunderstanding the image from Creality, it looks like a clone of INDX. Does anyone else feel the same?

Also, for some reason, I cannot attach any images to the Prusa forums. It keeps failing during processing.

INDX - Nozzle diameters

salus — Wed, 27 May 2026 06:55:43 +0000

Hello

I'm waiting for the upgrade kit from CoreOne+ to add 8 INDX tool, the order is done

The upgrade has all nozzles with diameter 0.4mm

So, when will be available other INDX nozzles with some more diameters, i.e. 0.2,, and 0.6mm?

Thanks in advance for answers

Regards from Spain; Salus

Gcode files - will they convert for INDX via new version of Prusa Slicer?

Not sure if this topic is best suited here or whether I should have put it in the Prusa Slicer sub forum.............

I've just spent considerable time (many hours) creating the bgcode files for this print from Maker World.
I had to export components to Prusa Slicer and then manually paint the MMU colour requirements and then slice to get a Core One + MMU3 bgcode file.

I was going to print on my Core One+ MMU3 setup, but given some components have very high numbers of filament changes, I thought I'd place the project on hold for a few months until I receive and install the 8 tool INDX system that I have on pre order, given the print time and filament savings that can be expected.

Does anyone know much about the future capabilities of Prusa Slicer and INDX? I believe a complete new version of the slicer will be released but am interested as to whether there will be a conversion path to INDX for existing bgcode files or whether I will have to abondon these & start again from scratch.

Idea: INDX for single-material multiple-detail-level printing

Patronics — Wed, 20 May 2026 23:52:35 +0000

I know there's been talks of using INDX with multiple nozzle sizes to, for example, have infill printed quickly with a larger nozzle, and external surfaces with a smaller nozzle, but has anyone considered the possibility of using multiple nozzle sizes with the same filament, based on the level of detail needed with specific regions of the printed object? I suppose it could effectively also be set up as if it were a multi-color print, and just using the same filament type on multiple nozzles, but I hope this is a feature that could get some attention and hopefully have a streamlined implementation at some point! It could save a ton of time on large prints that have a few areas that need finer detail, where otherwise the entire print would have to be printed with a smaller nozzle, taking much longer.

(as a very much over-engineering aside, this also has me contemplating the concept of a nozzle-changer that uses the same filament without using multiple spools as input, but that's likely not very practical or necessary, even if fun to contemplate.)

Expanding CoreOne after INDX

David Wood (dwuk3d) — Wed, 20 May 2026 12:10:41 +0000

Looking at expanding my CoreOne for things like elevating/interleaving tool racks so that I can go above 8 tools.

It looks like the MMU3 goes into the buddy expansion board, and the GPIO board goes into a spare I2C port in the main board.

Has anything been confirmed about which if any of these ports are going to be taken up by the INDX filament sensors and the double eddy nozzle alignment probe?

Ho
I hope it is not the GPIO port - as it looks like the GPIO hacker board with its additional GCode commands would be a useful method of driving additional features?

INDX and Blob of Doom

knightofcarnage — Sat, 16 May 2026 02:41:13 +0000

Does anyone know what replacement parts will be available for the INDX head? My primary concern is that Blob of Doom could damage the fully exposed induction coils. There are no silicone socks to provide any protection either.

INDX Price changes

FullMetalJumper — Fri, 15 May 2026 10:30:22 +0000

Have seen the price of the 8 tool INDX go up twice since it went out of stock.
Wonder how much it'll be when the 2nd round of orders are available.

What's your first CoreOne INDX print going to be?

David Wood (dwuk3d) — Thu, 14 May 2026 22:05:37 +0000

I'm planning on doing this 11 colour, 9 plate print as my first test print.

I've split the model up so that the most colours on a single plate is 8 - so should work ok hopefully.

It's a 27hr print on a rival 7 nozzle printer - so hopefully a bit quicker on the CoreOne INDX.

Will probably also do the smaller version pictured as a single plate - but will either need to do a few manual filament swaps, or dust off the Palette2 and P2PP to do a small number of swaps.

Will loading TPU be easier with INDX?

Mike Daneman — Mon, 11 May 2026 14:55:20 +0000

I know that the INDX print head has self-adjusting gears to avoid needing to loosens the extruder tension for soft filaments. However, how will the filament sensors work? Will they still have the same issue of being too tight for TPU that the original CoreOne has? Will the side sensors have the switch like the current CoreOne+. What about the sensor on the head itself? With my current CoreOne+, the only way I can load TPU (95A, not the super soft stuff) is to flick the side sensor switch, loosen the feeder gears screws, turn off the filament sensors, then remove the PTFE tube from the extruder and manually feed the filament in. I’m hoping it will be easier with INDX.
