possibly the worst 3d printer design.

What’s wrong with the design?
It looks like it would get more ‘shaky’ at higher Z. The cantilevered Y and the angle of the X drive belt also give me questions. That’s just going off of this photo.
I find it hard to believe that they don’t see major Z height differences when the extruder is extended to the front, like in the picture. They have the motor all the way out on the tip of that lever…
It may print, but it’s not going to get the kinds of resolutions that people want, at least not on wider parts.
Also, from what I can see, there is no bracing anywhere on the Y-axis of the printer’s frame, so even at the slowest print speeds, there would be extensive deflection and warping of the frame. It also looks like the Z-leadscrew is actually being bent in the photo above
The claims of 150 mm/s for “high quality prints” and 250 mm/s max are downright laughable.
This is mission impossible, 500 printers to make in this year alone, still have to finalize the parts for production…never gonna happpen. This screams fail all over the place. I wont even go into technical details.
