It’s the Invisible Errors That Matter Most—That Critical 0.1mm

I’m referring to my situation. I have an H2D and an A1. While the A1 prints perfect parts, both dimensionally and in terms of quality, the H2D is continuously wrong with the dimensions (it usually makes parts that are up to 5% smaller with any material) and the quality just isn’t there. There are very obvious layer shifts in some cases. After being enthusiastic about my A1, the H2D has deeply disappointed me.

Noticed the same thing, wrong dimensions, wrong holes etc. Why do I smell a weird way to upsell their vision encoder? The general consensus is “calibrate your settings” but sorry… its a 2.5k machine. its funny to say the least to tell me to calibrate a machine thats advertised and sold as a “flagship ready outta the box” . Issues upon issues upon issues, and dont get me wrong, i love the machine, and its build quality. I love its prints, but thats only when they are cosmetic and only when it didnt mess up purges, prime towers, supports and 10s of other stuff.

5% seems like a whole lot… On big prints that would be a deviation of 15mm or 1.5cm in each dimension… Not to talk down your experiences with the printer but I somehow doubt it.

I agree. I’ve printed quite some models that require assembly and fitment on the H2D is hit or miss, either too big or too small. Meanwhile my A1 has been printing dimensional accurate parts all the time.
