What's everyone thinking about PEEK (Or similar, chamber above 100c) on the CORE One? (Presuming everything functions properly, reliably and safely) Poll is created on Jul 13, 2025

Soon enough tough, Prusa will be releasing a firmware to support their new 400C hot end.

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.

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.
