INDX on core one

https://www.youtube.com/live/h82_0mZq_Tk?si=Ht00-Cge4D-0ezyW

Two versions 4 tools, 8 tools. 

Its an upgrade kit,  to add to a core one.   

Core one L upgrade not developed yet, will come

Claim max 40mmcubed flow rate.  Much more than nextruder. 

Nozzle sizes:

0.2 0.4 0.5 0.6 0.8

[Kurt Gluck]

Price, for upgrade:   In Euros.   499. For 4 toolheads  699 for 8 toolheads in addition to the price for the Core One.

[Bryan Eckert]

Prusa's own website directs you to Bontech to order it, and they don't mention anything about a native machine with the INDX, only the add on kit, which is $699 for the 8 color ($499 for 4).

So a Core One with 8 color system will be just south of $2K, and the L will end up at $2500. Which is a much better deal, as it's only slightly more than the H2C base with comparable print size.

I want it for the XL ! :-)  I wonder how many tool heads you could fit.  

[Bryan Eckert]

I'm seriously hoping SOVOL picks up the INDX and releases the SV08 with the system. Since the SV08 is a voron clone, should be easy to integrate.

I would imagine that multiple teams and individuals are working on mods now.

Okay, I've got an INDX question that's been eating me since yesterday, and no one has posted anything about it that I can find:

How does the INDX do tool/nozzle calibration/alignment?

Are we going to have to wait for the reviews to come out to answer this question?

I can probably guess. But that guess assumes that Prusa has cooperated with Bondtech on the Core One firmware. 

I’ve been considering putting INDX into my E3d and the RRFW will let me do this alignment. … but the RRFW reads the tools as separate heaters so I’m not too sure how that would work at all. As such it’s naive to assume INDX can be applied as a decoupled upgrade. 

Bondtech should make their own 3d printer.

[Jody Harris]

My understanding is that Prusa and Bondtech worked very closely together on the INDX. Since the Core One INDX is the showcase product, I'd assume that Bondtech+Prusa did everything possible to make the first product as shiny as possible. Seeing that Prusa just walked away from all of the work they did on the Nextruder says a lot about their confidence in the INDX.

On RRFW, my Boss Delta runs RRFW. It has two extruders that run through a single hot end. The firmware assumes that each tool has it's own heater, so the screen and web interface display the hot end temps/fans/etc individually even though they are the same sensor. My guess is that it will treat the INDX the same way. I'm sure you'll figure it out. I don't expect that to be a roadblock for you. I'm looking forward to your E3DTC->INDX conversion journey. I've been listening since you got the E3DTC, and it's been an interesting journey so far.

Bondtech making their own printer could be a point of contention with their industry partners, but tomorrow that might change. 

I'm planning on doing the INDX upgrade to my Core One in the next six months (giving it some shake down time). I'm glad you started the tool changer journey early so the rest of us could ride along and enjoy the fruits of your labor and learning when tool changing came into it's own.

As I understand it the index itself doesn't do any calibration procedures or alignment. It would all be related to the firmware you would have to manually configure the tool socket locations and enter the coordinates on the tool location for each tool head and either go through and do manual offset calibrations or in the case of the prusa tool changers they have macros and a camera that calibrates the XY position for each head. There is also a tooling ball setup that has been developed within the Klipper community that that physically measures the nozzle from the tip and then four locations on a perimeter to determine the XY and  Z height offset. If you want to see that device in action the Teaching Tech channel on your dropped a results summary from their collaborative build of a Sovol SV08 tool changer and it uses the tooling ball setup for calibrations.

The XL does not use a camera for calibration. Actually,  having a camera on any prusa printer is an option, and you used to have to add it on yourself.    The way prusa does internozel calibration on the XL is you remove the build plate and put a slightly beveled pin in the center of the plate and the printer taps the pin on all sides and at different heights with each of the tools.  This tells the printer the offset of all of the nozzles from each other.  THEN at the start of every print the printer heats the bed up and lets it settle then it takes one nozzle and taps the bed with it, this tells the printer the offset of that nozzle from the bed.  It already knows the offsets in xyz of all the nozzles from each other.   It then goes around and taps the bed in the area it wants to print, this tells the printer the bed mesh, you know how the bed dips and where its tilt is etc. 

The Snapmaker does something similar, instead of a beveled pin, it has what looks like a beveled hole in the print bed and its in one corner instead of the center, basically the same system.     I believe the bamboo H2C goes and taps each tool someplace to figure out the intertool offset as well.  

The question is, do you have to do all this tapping once to calibrate, once for each print or once each time you switch tools...  This is a matter of taste, what you feel is important (reliability vs speed) and the particular way your printer is built including the size of the build plate and how ridged it is.

PS: I believe Steve of Steve Builds YouTube who seems to be a big voron dude already has the INDX in his hands for developing voron (kilpper) software.   One path to fame (within a small world) would be to figure out how to do it for marlin  (sailfish anyone? ) :-)

I don't know the details yet but expect that the force sensing of the Nextruder might be included in the INDX, otherwise it would be a major step backwards for Prusa. This would allow Prusa to re-use all their XL firmware and alignment technology. Does anyone know yet?
