ArUco QR Codes ⧸ Original 256x256 Build Plates

More ArUco QR codes. Why? Because these are simply easier to use. Positioning is almost automatic, installation is semi permanent with adhesive tape, and the best part is that you can assign custom names.

I can see that a plate is Textured PEI, but I can’t see whether it’s covered in hairspray, magigoo, or liquid glue. Now I can.

I’ve got quite a few old original Bambu build plates for A1, P1S, P1P, X1, and X1E printers lying around and none of them were recognized by my Printer. 

Throwing them away was never an option, and printing new codes is easy. Now it’s even better, with freely selectable names. No more mixing up a magigoo PC plate with a magigoo PA one, and most importantly, no more printing TPU on a bare plate by accident.

PETG works surprisingly well for this, even at 110 °C, and should be considered the minimum. ASA or PC would be the premium choice, but PETG is absolutely sufficient in practice.

The codes attach perfectly using 3M 9080 LED tape, 8 mm wide and 0.15 mm thick, which is heat resistant and ideal for this application.

If you’ve got 256×256 mm build plates collecting dust and a P2S, this model gives them a second life without giving up automatic build plate recognition. This also works with cheap Asia clones, as long as they have exactly the same dimensions as the original Bambu plates. Sorry, BIQU fans.
