I’m here to shill for Qidi again whenever their name comes up. I’ve owned two, an OG X-Plus and currently an X-Max 3. They’ve both been rock solid, unpack from the box, and print. My only gripe about the Max 3 is that they are not extending support for their new AMS-esque filament changer doohickey to it, but that wasn’t even on the horizon back when I bought it so I guess I can’t be mad about that.

Thus far Qidi’s machines have been reasonably open source, with readily available parts, and they haven’t pulled any lock-in bullshit. You can run your own firmware on them if you like as well, since the controller boards and so forth are commodity parts.
