XL 300 BOM

Anybody know of one? I've been searching.

In particular does anyone know if the XL300 basic kit is supposed to come with a 300mm glass sheet?

As far as I understood, the XL 300 just printed on the alumium heat bed.

That could be, the sheet seems a little thin for that so I thought it was merely a heat spreader but what you say makes more sense.

Can the inductive sensor work with a glass plate?

My plan is to have PrintBrite/Glass(3mm)/Aluminum/Heater

It was working with my Mk2b PCB and the glass supplied while I was using the Ramps/Mega combo. It didn't work when I switched to the Duet 0.8.5 board though which I imagine was due to the change from 5V to 3.3V and couldn't be bothered to spend the time making the voltage divider circuit work.

It would depend on the thickness distance between the top surface and the aluminum being smaller than the sensor detection range so the sensor can trigger at a safe height above the surface and just use the Z offset to tell the printer how far to go down past the sensor reading to start printing.

Thanks. I'll give it a shot with the supplied electronics and let people know. I have a BLTouch that think would be interesting to try after I get things working.
