RE: HT CORE One: 500c Nozzle and a Fully Automatic, Inputless, Actively Heated, Insulated Chamber
Soon enough tough, Prusa will be releasing a firmware to support their new 400C hot end.
RE: HT CORE One: 500c Nozzle and a Fully Automatic, Inputless, Actively Heated, Insulated Chamber
If the TDS is to be believed the mechanical properties are pretty good. It remains to be seen what can be achieved while printing especially in the Z axis but it is promising it already seems good. I wonder if the core version is abit easier to feed into the nextruder. Looks like I will need to do some minecraft and print that idler with PLA and then reprint when the time comes with ppa then pps lol

When do you think that might be? I see in master they already have the PT1000 and PT100 definitions. I need to check for the adc adjustment hopefully its there too. I also asked in a seperate thread about the thermal model for the hotend. This feeds into the PID loop. Do we know if that is being adjusted for the new hotend? It looks good but I was impatient and got some copperhead hotblocks too.
RE: HT CORE One: 500c Nozzle and a Fully Automatic, Inputless, Actively Heated, Insulated Chamber
I would expect the new firmware will be released before the hot end is shipped. They have it listed currently as "not in stock": HT Hotend Upgrade
I pretty sure they are busy at the moment patching all the XL bugs that were introduced with 6.4.0.
Also, I would expect PID tuning to be exposed in the firmware rather than running M303 and manually injecting it into the startup g-code.

Hopefully it won't take too long. I think alot of these settings should be accessible in a yaml file or something similar in the prusalink web interface they already have.

Morning all! I've been lurking the forum having recently purchased a Core One just before last summer. I use my printer for prototyping and technical builds rather than pretty toys etc. I have become excited when seeing that printing at up to 400 degrees C has become a potential option, but little frustrated Prusa hasn't given a release date. I was wondering if anyone has an inside scoop on the potential release date as trying to design whether to outsource part production, buy another brand of printer or wait it out.
Cheers!

If I were to guess, it will be in late March or April to coincide with the new PrusaSlicer 3.0 and INDX upgrade for the Core One.

Thats what it looks like from here too: https://www.reddit.com/r/prusa3d/comments/1qwikj6/comment/o3q16rh/?force-legacy-sct=1
Annoyingly the github doesnt seem to be up to date as I see no mention of the pt1000 even though they clearly have a beta firmware they are testing. I wish they would update a branch with that beta version so we can flash it ourselves.
RE: HT CORE One: 500c Nozzle and a Fully Automatic, Inputless, Actively Heated, Insulated Chamber
Thanks for that information. Shame it is so long away, going to have to pull the trigger on another option as that is a bit far down the road. 🙁

There are two github repos. The public repo is only updated on day of release. From what I remember they only update it from the release branch and not from the betas.
RE:
Saw a funny quote the other day:
The people who really need to print PEEK will not be screaming 'Why doesn't my printer handle PEEK?' because they will already own a printer that can handle it.
I can't think of any use case where I casual hobbyist need to print exotic plastics. I can think of one for myself since a newer hobby is high powered model rockets. But I think I don't need to go any further than PPA-CF.
RE: HT CORE One: 500c Nozzle and a Fully Automatic, Inputless, Actively Heated, Insulated Chamber
PPA-CF is pretty high performance already and it needs higher temperatures and there exist use cases for the PPS as well. At any rate this isn't really a valid excuse as it quickly degenerates to, whats the point of having the printer at all just buy the thing ready made. Polymers with nice properties exist and people want to use them. Anyway these discussions have been had on reddit and I don't think anyone suggested you would be able to print PEEK.
Where is this second github you mention?
RE: HT CORE One: 500c Nozzle and a Fully Automatic, Inputless, Actively Heated, Insulated Chamber
I agree, no interest personally in using expensive polymers like PEEK, but totally would use PPS or PPA. I have been designing and test printing performance motorcycle engine parts using PA 612 CF and it's worked well for reed box manifolds in testing for a week or so. I was planning to have the final components made in aluminium but then the recent Prusa HT hot end has made me think could do it inhouse and reduce costs for many who are interested in purchasing by using PPS CF or GF. April / June is a long way away, so thinking to go back to looking at aluminium again. I might try using PA12 CF and use at 100% density to see how this works out in any case. The test ones were 40% infill and maybe 4 layers and worked fine.

I've said this elsewhere, but no one who really needs to print PEEK is screaming "Why can't my printer handle PEEK???" Those who need to print it already have a printer capable of doing it.
The second github is Prusa's internal (and private) github.
