I was able to deal with my overshoots by increasing lookaheadwarm and bumping power up a few thenths.

No idea what the pulsing the oven when its over wantedtemp is, something with the currentDetla (<mispelling) but I am not sure what that code does yet or what the variables you chose are

I am assuming some kind of swing 5, 15 and 172 and base 32, 128
Might look again later and see what the math is doing.

I think alot of these issues are precision issues that do not present on the samd21, I am waiting to get one to be able to PR against master without breaking stuff or fighting other bugs.

Seems everything is a float and does not need to be, there are also alot of comparison warnings with -wall so might be any of those , I also have better luck sometimes by disabling lookahead, maybe it your oven is fast enough it harms more than helps
