PID autotune doesn't stop heating the bed. #164

Just built a coreXY with a Robin E3 and I've installed a mains heater for the bed with a new known good brand SSR, have changed the values for the new thermistor (11 as it's an Keenovo thermal pad) in configuration.h as well as thermal_protection_bed_period and watch_bed_temp_period in configuration_adv.h but the bed just keeps on raising the temp. Started PID autotune set to 70°, reaches 70°, keeps 70° at first cycle, starts second cycle and pushed reset at 92° (went to make a coffee).

Will the heating bed automatically heat up when it is turned on again?

It heats up when I set it to heat and stays at the requested temp, but can't do PID autotune because it keeps on heating up at second cycle.
