1000 Watt seems to be very very high. Magnets looses his strength at high temperatures.
I prefer to use a magnetic foil and a ferro foil. So you have the whole surface as magnetic area. -

Rare earth magnets handle higher temperatures than standard neodym magnets (there are high temperature neodym, but they are more expensive).

I have a similar setup.

@fma
i am using Samarium-Cobalt magnets 5lb's pull each, good up to 570 Deg.F -
@gone2far
Ultimately I want to do PEEK, Carbon Fiber, ect engineering grade materials.

Is there any effect on the silicone heater from the magnetic fields?

No, but some probes can be affected by the magnets. BLTouch for example. Maybe others?

well that could suck, my BL Touch is to be delivered Thursday. any way of sheilding the touch? wire wrap or something?

@dallash I'm not too sure really. If it does end up affecting your heightmap you can manually edit the .CSV file to bring the erroneous points in line with the rest.
It's possible the newer BLTouch aren't as effected by it?
So definitely report back.

@dallash There is an option "B1" to stop the bed heater during probing:

Railcores probe a mag bed with a BL Touch between the magnets. Do not know if you could do that with the spec of your magnets.

Thanks for the insight, I will post results, i'm still a couple weeks away from running, waiting for a new design Bondtech Bmg X2 with direct mosquito mounts. still machining parts for the print carriage
