Annoying warning
-
Warning: Heater 0 predicted maximum temperature at full power is 215°C
Where does it come from and how to get rid of it?

@tecno Looks like your heated bed is quite overpowered, it would be better to reduce its output if possible. If you want a work-around, you can increase the maximum allowed temperature of the first heater via M143 before calling M307. That warning message is output if the predicted temperature exceeds 50% of the configured limit plus another 50K (degC).

Hmmmm
Moved M143 lines to before M307 lines and now I get this

@tecno Makes sense for H0 and H1. Maximum temperature for H0 is 120C (warn threshold 230C) and the maximum temperature for H1 is 280C (warn threshold 470C). Both predicted temperatures exceed the warn thresholds.
I don't know where the third warning comes from, perhaps from your config-override.g or later somewhere else in your config.

@tecno You have quite different M307 commands in your config.g compared to your config-override.g.
config.gM307 H0 R0.647 K0.182:0.000 D2.23 E1.35 S1.00 B0 M307 H1 R2.943 K0.349:0.411 D6.80 E1.35 S1.00 B0 V24.6config-override.g
M307 H0 R0.654 K0.274:0.000 D1.90 E1.35 S1.00 B1 M307 H1 R1.916 K0.577:0.000 D10.84 E1.35 S1.00 B0 V24.6I expect the ones in config.g trigger the first two warnings, then only H0 is triggered by the M307 in config-override.g. If you're using config-override.g, you can remove the M307 commands from config.g (they are being overwritten by config-override.g anyway), and then you should at least get less warnings.
