My PID looks like: https://imgur.com/ls1jUs7

It's going over by nearly 30 degrees on warm up with 200 degree target Note: second tuning attempt the first was at 180 and it failed with roughly the same curves.

Hardware: BIQU H2 BigtreeTech GTR V1 Also a BIQU Hermit Crab (shouldn't be a problem but it's between the two so I'm noting it)

The only time I've seen a curve like this was with a bad cap, I don't see reports of this problem with this board am I missing something obvious?
