Core One L launch
Well, congrats on the product launch. "Actively heated chamber" and "AC heatbed" ticks just the right boxes, startup time with non-PLA on Core One has potential for improvement. Let's hope for a controlled trajectory.
RE: Core One L launch
Um, Someone in Prusa please proof read the announcements.
If the core one was truely 0.95M3, I would be buying one now. I think they mean cubic feet, not cubic meters in the chart. Unless my math teacher taught us wrong.
Also I have been logged in and have tried 3 browsers, windows and apple based OS and I cannot reply or add comments to the blog. Neither can I get the video to work. Keeps asking for me to set cookies, over and over and over, even logged in and re-opening the page. I guess the web group is not ISO certified yet.
All the above aside, the Core 1L seems to be targeted to top end hobbyists and business use. I hope the heat bed will be an available option on the Core One. Serial vs. Parallel wiring to switch from 220 to 110 v is a good design. Higher voltage means about 1/5th the amperage needed, or smaller wires.
Need to see how the aluminum plate is mounted to account for the growth during heating. A 90C change from room to 110 could cause the aluminum plate to grow to 306.2 mm. Cast aluminum maybe a little less, but not much.
One question I do have, is it the same buddy board, or a new controller to support the advanced options and new heatbed? There must be a relay for the AC power switch somewhere.
RE: Core One L launch
Why is an AC bed beneficial? Less energy through the PSU?

Yes, a PSU is expensive in $/W for several reasons, where AC is just an inexpensive Triac circuit.
Implicitly it translates into "higher power", let's hope that "translation" is correct.

It is a new board for the printer and a new section to control the heat bed.

On reddit there was a note that it may be considered for future Core One S or as an upgrade, but because of the electronics and requirements for the 110V it will be a quite expensive upgrade, if ever.
One more thing, there wont be an upgrade kit from Core One to Core One L, because effectively it is so many parts it is effectively a new printer.
