I don't like it for a few reasons;

1. It looks like you are going to fight "ringing" with lack of rigidity.

2. Its a bowden extruder... which I suppose is a necessity due to the lack of structure. Still I would rather have direct drive on every machine.

3. It's very expensive. You can buy an Ender for $200 or less on sale... or around $230 normal price. Upgrade the board to a 32bit Bigtreetech for $60 with Trinamic drivers... plug and play.

4. Most people find they want a bigger printer... not smaller.

This is my initial reaction. I am always looking for innovation in this space and most of it is happening in the "industrial" realm. For example, I wish they would make an SLS machine or a "beginner" industrial machine.

The companies like Creality are just dominating everything.

We need prosumer/industrial machines that have features you can't get with $750 dollar machine.

Re: points 1 and 2, I think they're connected. The lack of rigidity is mitigated by the Bowden making the hotend so damn light it probably won't be as big of a deal as you might think. Also tweaking some jerk and acceleration settings will almost always fix ghosting and ringing caused by a "less stiff" frame with minimal hit to the print time. (And I'm assuming they'll do most of the legwork to have a great printing profile out of the box)

>You can buy an Ender for $200 or less on sale...

This is exactly why I love the idea of this printer so much more! You could get an ender for $200 (plus $60 to $100 to improve the worst parts and make it less likely to catch fire). But you're still manually leveling, you're still fighting with scraping prints off the bed, you're still missing stuff like filament run-out detection, automatic firmware updates, spring steel PEI print surface, crash detection, power panic, stealth mode, and a lot of other safety features.

And at the end of the day, an ender 3 is gonna cost $260 to $300 and require the user to know what to replace fix on day 1 for a safe printer, while this is $350. And outside of commercial manufacturing, most users don't ever max out their print area with most printers (at least from what I've seen spending a lot of time on 3d printing forums).

I'm super excited for this, because $800 to $1000 is just to much for the average person to spend on an easy to use printer like the MK3S. This is only slightly more expensive than other "starter" printers, and has most of the niceties, safety features, and support.

I had exactly the same reaction.

But,I will say that my creality has been a bucket of pain, to the point where I almost exclusively use my prusa these days. So perhaps that's reason to hope this is more than just a crappy bargain basement printer warmed over.

Yes, if you don't value your time then yes, buying an Ender and modifying it is a better deal.

I am part of a Spanish 3D printer group called "clone wars", and dozens of people there have bought Enders because they are dirty cheap.

It really takes a master degree in engineering to solve most of them, because they want to print professionally expending 300euros.

That connects with the point 4, yes people want everything, expending nothing. But that they could get it is a completely different thing.

As the print bed goes bigger, the mechanical deflections increase with the square of it.

The price of things like milled precision beds or original linear rails, increments non linearly for a tolerance when the size of the bed increases.

I've owned an Mk2s for like 2 years and I've never printed anything that required all the bed length.

My next printer will be smaller, let's see how they'll price the kit version.

Isn't they have SLS machine?
