Experiences with the Mini IR and PEI

Well first i tried a PEI surface on a glas bed and black alunminium beneath. Big surprise it didn´t work. The deviations were extreme. The map looked like a landscape with a lot of mountains. Then i managed to get some PEI without the glue sheet preinstalled. As adviced i use a oven coating on it and placed it for two hours 170° in my domestic oven.
First impression after the installation. I´ve never expected that level of accuracy. I don´t remember the values but they were amazing and the repeatability...
But i had to use a little force to get some printings of the PEI. Doing so caused the coating to be partially seperated from the PEI. Luckily i use 3 Point Leveling to correct the tilt and the places where the sensor measures are still intact. But i´m afraid sooner or later the PEI will be unuseable for the Mini IR again...
I thought i share my experiences and ask for suggestions. Are PEI and the Mini IR a impasse?

@rivam I've found with PEI, a looser Z0 isn't as hard to remove a printed part.

Can you share the details on the oven coating procedure? I'm having a heck of a time with the IR sensor and my PEI bed...

Scroll down to Bed Surface and there it is in the last paragraph. But it is necessary to have a PEI Sheet without glue on it and a seperate adhesive sheet like the 3M 468MP. But as i already stated i´m not satisfied with the result yet. Maybe the coating didn´t "connect" to the PEI sufficiently... Might depend on the used spray. I can´t find the one i used but this one seems similar BBQ and Stove Paint
Perhaps try a longer or higher temperature in the oven. I don´t know how far you can go though.

Ive got a Tronxy X5S upgraded with my own mods. I have this glass bed https://www.amazon.co.uk/gp/product/B07FLBLTXF/ref=ppx_yo_dt_b_asin_title_o06__o00_s00?ie=UTF8&psc=1 and DC's IR bed sensor. I purchased a matt black peice of card from WH Smith, cut it to size and placed it between the bed and glass. Everything works a treat and my heightmap could not be better. My prints are top notch too.
