  1. Works well, happy camper! Came nicely packaged, pre-soldered, glass was flat, and it worked. Wires were well attached (good solder joints), thermister was the expected type and seems to read accurately.Currently the two are clipped together and serve as the only build support. With blue painters tape on the glass, the PLA prints stick almost *too* well… 🙂 (can’t speak to ABS as I don’t use it)Final shot is a 180mm x 180mm x 5mm flat block to test flatness and adhesion for a large object…

  2. I couldn’t find an aluminum bed to replace the one on my Anet A8. The aluminum adds stability to the bed. The actual MK2b Heated bed is rather flimsy, but when you add the glass on top, it is sufficiently strong for 3d printing.It heats up quickly for a 12v bed. You can change it to a 24v bed, but you’d have to resolder the connections. At 12v, it struggles a bit trying to get over 100c but it’ll get there, and seems like it wont overheat the connections.Overall, I…

  3. I’ve had this about a week now. The glass is solid and flat, and the board is easy to install. There is a slight curve to the PCB board, but it doesn’t matter when the glass is put on top and clipped down with black binder clips. The solder connections are well done and do not appear to be cold-soldered. The temp element matches my E3D in the print head exactly. The board heats up in a reasonable amount of time, though I only use it to about 45C. I tested it to 100C a few times and it does it…
