I would expect on the core one it would be similar to the xl

If you watch 3d musketeers video I liked earlier he discussed this with the lead guy on this from bond tech

Problematic design

Anthony Rothert <pghp8n...@gmail.com>: Nov 20 09:33AM -0800 I agree that the V400 does a great job withTPU. I have a spool of Siraya Tech 85A. The A1 Mini did a poor job of printing anything other than small single parts… not even sequentially printing the same small parts worked well using the 85A filament. With 95 A, the A1 does great also. I was amazed that the V400 handled the 85A great with very little setting changes. I’m admittedly too lazy to put much effort into printer tuning for perfect prints. I simply don’t have the time or patience. If I want high quality dimensionally accurate prints in anything but TPU, I just print on my A1 Mini or my new P1S. If I want something in soft TPU or something big in PETG or PLA that doesn’t require tight dimensional accuracy, I use the V400.

INDX on core one - can be ordered shortly

Jody Harris <jha...@harrisdev.com>: Nov 20 03:12PM 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?   -j   Think carefully

3D Printing Tips and Tricks <3d-printing-...@googlegroups.com>: Nov 20 08:24AM -0800 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.   On Thursday, November 20, 2025 at 7:12:13 AM UTC-8 jha...@harrisdev.com wrote:

Jody Harris <jha...@harrisdev.com>: Nov 20 05:06PM 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.   -j   Think carefully

Sean <sean...@gmail.com>: Nov 20 12:21PM -0500 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.
