There's a lot to be said for assembling your own 3D printer, it gives you a better understanding of the functions.

Which is exactly why I built my AR-15.

(Protip: if one of your stepper motors is actuating backwards, the clever souls who designed the system used non-polarized connectors, simply unplug rotate the plug 180° and plug it back in. Easy-peasy once you know the trick!)

I never knew that was an issue. I'll be sure to check for it.

I don't see any cross bracing on the frames, little to keep it square but meticulously tightened bolts that may be subject to loosening under vibration.

Perhaps blue LocTite?

It looks like a good first printer, you'll learn the capabilities and limits of FDM, and will be well armed with a want's and don't wants list should you decide to upgrade.

What does FDM stand for?

Made in Shenzhen, customer support may be, ummm, challenging.

I hear ya. Still suffering with a Zosi home surveillance camera system.

Thanks for the hints.

FDM = Fused Deposition Modeling.

Plastic is melted ("Fused"), extruded, and Deposited to make a Model.

The name predates the use of the technology to make actual functional parts...

Fused in this context also means to join together by melting, and the extruded liquid is hot enough to partially melt and mix with the surface of the preceding layer.
