I decided to give DC42s IR probe a try and needed a mount that would work with the stock Rostock effector.

If anyone is interested here is the mount: http://repables.com/r/762/

Thanks for a link to the mount and the picture you have posted. I wonder if the IR Probe would have difficulty with PEI attached to the glass?

, I look forward to tinkering with it, may have to adjust the diodes like Xenocrate's recommends.

It works great if you paint the back of the PEI matt black first. I used spray on barbecue/stove paint and cured it in a domestic fan oven at 170C for a couple of hours. After that the paint adheres really well to the PEI. The reason for the paint is that PEI is transparent to IR, and you don't want the variable reflection from the adhesive and the air bubbles in it to interfere with the reflection from the top surface.

Thanks for that info dc42, I would not have thought of the painting black the backside of the PEI.
I assume that after it dries you can apply the normal adhesive.

Thanks dc42!

Yes, I used 8153LE adhesive sheet, but 468MP should be equally suitable.

I was unable to get the bbq/stove paint to bond to the PEI sheet(tried krylon and rustoleum paint brands, multiple paint types, multiple PEI suppliers, cook times and temps). I was about to give up on using PEI with my mini height sensor board, so I tried one last way. I applied Kapton tape to the PEI using the window cleaner float method and then applied the 3M adhesive the same way to the Kapton PEI sandwich. Works Great! Just wanted to share in case someone else was having the same issue.

Curious what brand paint do you have success with?

I used B&Q own brand barbecue/stove paint. I sprayed several thin coats on allowing it to become touch dry between coats. After curing the paint in the oven, I tested it by putting sticky tape on it and then ripping the sticky tape off. The paint stayed behind.

One side of my PEI was glossy and one side was slightly matt. I painted the matt side. I cleaned the surface with isopropanol before spraying.
