I've watched the Jessy and CNC reviews. They're both glowing with praise. The main criticism being the price. 

Buyers who care most about price are unlikely to be swayed. But this is a much more affordable printer than the XL and a more competitive printer than the MK4S. I've gotta say I like my XL and I use it a lot, but the Core One should have been released first.

RE: First Unboxing Videos are live.....

I watched a couple of unboxings and reviews this morning and they all seem pretty good. I'm super excited to replace my ancient (though still fully working) ender 3. I'll end up turning it into a pen plotter or selling it really cheaply/giving it to someone local to me.

I think the "CNC Kitchen" review is the one to watch on Youtube. Stefan did quite a bit of actual printing, assessing speed and print quality for various print sizes and materials. He also ran "blind" quality comparisons with two of his mates, comparing prints from the Core One, MK3, MK4S and Bambu X1C. Based on these, he comes up with a balanced assessment of the Core One.

It's often easier to introduce a new (to the company) technology in a higher-end product first. You don't have to optimize for cost at the same time as getting the new technology to work robustly. And if something does not go to plan, you have fewer customers to take care of -- be it by consoling them for a shipping delay or by providing retrofit kits to fix hardware issues in the field.

Also, I think the higher-end and professional market will become increasingly important for Prusa. With some Chinese competitors no longer competing just on price but also driving some actual innovation (and making it affordable due to large unit numbers and optimized design-for-cost), the mainstream consumer market will be an increasingly difficult playing field for Prusa. They will need to move upmarket, and may deliberately have staked a claim with the XL first.

I also liked the video from Stefan, however I think some of the problem he has faced will be fixed with firmware updates and tuned profiles in the slicer. The more people starting to use the printer, the better the feedback gets.

Yes, it was good to see in the comments that Joe Prusa himself replied about the overhang issue (possibly due to insufficient chamber cooling), pointing out that the fans currently run at 40% max. So there is room for tweaking the settings, and I trust that Prusa will do that. They need to -- this printer really can't be slower or provide worse results than the MK4S or the competing Core XY printers from Bambu Lab.

I'm still waiting for mine, but I expect we will see intake fan mods at the top soon. The problem is that the ventilation opening is at the top and the outake fans too. You don't get the cool air down to the headbed, that would be my guess.

I think that the placement of the fans and air inlet is very deliberate and reasonable. You want to cool the air in the build chamber right where the printing happens (to make sure the filament cools and solidifies quickly). If you wanted the heatbed area to be cooler, just reduce the heatbed temperature?

Why not just leave the door open when printing PLA/PETG?

Why not just leave the door open when printing PLA/PETG?

Two reasons for me:

(a) The ability to "do things properly" and keep the door closed no matter which material you print is one of the differentiating features over Bambu Lab, which Prusa has stressed quite heavily. They even install a door interlock as a standard feature, pointing out the printer's ability to operate with the door closed at all times if you want that for safety reasons (e.g. in an educational or company environment).  It would be kind of embarrassing if this did not work as advertised.

(b) My printer lives in the basement, where temperatures can be on the chilly side even for printing PLA and PETG, resulting in warping. I am looking forward to the temperature-controlled build volume to make that a non-issue.

RE: First Unboxing Videos are live.....

I've actually had warping issues with PLA on my MK4S when printing large square items (ie: shelves), and ended up solving the problem by covering my printer with blankets to keep some heat in. The ambient room temperature isn't even that cold (21C) so I'm not sure why I had warping issues, but am looking forward to the fully enclosed chamber of the Core One.

I have never opened the doors on my enclosures for PLA and I've never had any issues.  I don't design my parts with steep overhangs so the overhang performance is not a big deal for me.
