RE: Core One / Print Temperatures
You can print the PPA-CF at 290 degrees. If the part needs to deliver maximum mechanical performance, a higher nozzle temperature is always better because it improves layer adhesion. As parts get larger, a stable chamber temperature is recommended.
Mods for Core One: Core One HT 450 degrees, Comfortable display , Very fast print start and Reducing noises
Mods for Prusa XL: Very fast print start
RE: Core One / Print Temperatures
Well yeah i guess higher is better for adhesion, but this thing is indestructable already, with propper orientation it should be super strong even at 290C!
RE: Core One / Print Temperatures
I just wanted to chime in as I think that the lack of active heating is what is keeping this ecosystem from really standing out.
I own an H2D and Core One Plus. I enjoy the workflow of the prusa more. Print quality is the same on both but I think the Prusa is superior, why, because I know what the printer is doing vs I have zero idea what the automatism of the h2d are compensating for. That and the idea of sending any information, to china, does not sit well with me. They are known thieves and have advanced technologically fast for many reasons, including stealing.
Anything that I consider it to be an original IP, regardless of volume, goes through my prusa always. I do not trust the H2d nor their cloud.
Rant over.
THAT SAID, Prusa, you need to step up your game. Even a BL entry level has internal filtration and active heating. WAKE UP. You dont even have a proper AMS yet and has just release a dry box as if they had invented gun powder. Print quality, repairability and cloud connectivity will not cut it.
The HT90 is also no longer competitive, when better printers suchs as the IDX22 by Vision Miner is now in V4 and continues to grow. It is the go to platform for anybody printing engineering filaments here in North America hands down, the best current bang for your buck.
Nobody will ever buy an HT90 here when you can get the vision miner for just a little more (a few thousand dollars difference yes but this is a minor difference in a commercial graded machine).
Prusa's market, company and vision relies on their filament and overpriced entry level printers and they seem to be gauging their client base with piece meal updates that are behind the times.
The IDX is a great addition but I am not spending 5K to print PLA and PETG when I can do the same for $800 with almost any other machine in the market. The INDX will only shine if it can mix reliably, most other entry level engineering materials relieably, which it can't really. The INDX system will be greeat to have all sorts of different nozzles at hand, different material and have a printer that can print those reliably.
TIME TO WAKE UP PRUSA.

Of course. With Siraya Tec PPA-CF and 290 degrees, you'll get great prints.

RE: Core One / Print Temperatures
I'm relatively new to printing engineering materials, but ramping up reasonably quickly, and bumping into some of these issues already. I spend a lot of time manually switching between prototyping filaments & engineering each day. I don't need multi-color, I need two or three toolheads loaded up with, e.g. PLA, PA-CF, and possibly HIPS, ready to go. INDX sounds ideal for this, except it is limited to 300C nozzle temp, which eliminates a couple of materials in the 300-400C range. I recall they said it would be "at least 300C" with people speculating around 330C, not long ago. Will there be a 400C option for INDX? That would be good to know.
With extra insulation, I can easily reach and maintain a 55C chamber temp with the default settings, for the models I've printed so far in this configuration. I don't know how well that would work for max build volume. The temperature will climb higher if you disable chamber temp but I'm not planning on doing that with standard hardware. I think there's a PID loop control for the heat break which uses the print cooling fan above a certain point, but I can't bring myself to look at any more C++ code today.
I'm likely not a typical user, but OTOH I am seeing a lot of people in e.g. automotive communities getting interested in things like PPS-CF after seeing it on social media.

I have doubts that the INDX will support a hot end temperature above 300°. Another thing to contend with is the expanded and still passively heated chamber with the INDX attached. I would be curious if it's still possible to get to 55° with this setup. The INDX is not really touted for engineering filaments. There are better setups for that such as the Bambu H2D.
As for PPS-CF, that is currently beyond the capability of the Core One since you need >310° to print it. As for chamber temperature, with the latest firmware 6.5.3 the fans will cut on aggressively after 55°.
I do a lot of PC prints with HIPS as the interface material. Having at least 2 heads and active chamber heating is a must. That's why I purchased an H2D. The Core One I'm keeping for multi-color once I have the INDX in-hand.
