Hi!

For this topic are so much informations out there, it is really a mess and I need your help.

I planned on just use one print plate out of plywood (as it says on the i2 wiki page), then the heated bed and then a glass sheet with kapton tape.

1. Do I need something between the plywood and the pcb? aluminium? air?

2. Is it enough to just tape the thermistor with kapton to the pcb somewhere near the middle?

3. is it correct to have the bottom side of the pcb (with the traces) facing up if using a glass sheet?

Thanks!

Your plan should work fine. You dont need anything between them, air is a very good insulator. I do more or less the same thing. Only difference is I use a 3mm aluminium plate instead of ply wood (its lighter) and i think it looks nicer.

Thanks!

How much air/distance should be between the wood and the PCB?

my gap is about 12mm.
