Your heater is over-powered. The E3D heaters are rated at 12V or 24V depending on what you order. If you are using a 40W 12V one on 19V, it will generate 100W, which is far too much. The "bad curve" fit message is produced if the gain is more than 1500 - which implies that your hot end would heat to around 1500C if left on at full power.
For safety reasons, I strongly recommend that you get a lower-powered heater. A 24V 40W heater would generate 25W @ 19V, and a 12V 25W heater would generate 62W. You might want to consider using a 24V PSU instead of a 19V one, it will make heaters, fans etc. easier to obtain.
For now you could try plugging those values obtained from tuning into M307, but instead of 1529 for the A value, use 1499.9.

By the way, is there an option to use two different bed.g files ? I sometimes use smaller glass sheets on top of the aluminium bed and would like to have a separate leveling routing for that size of glass. The only thing I can come up right now would be to create a macro with everything needed inside. Is this the right way ?

I'd like this option too, or at least have the print pause.Quote

Please can we have the option to disable the safety checks. After several days of printing I get random errors on the bed heater or the hot end which go un noticed for a while as the printer keeps printing in the air but wrecking a meter of a filament each time as the extruder can't push it through a cold hot end.
