Send M308 S1 and M308 S2 in the console by itself to see what it reports.

Error: bad model parameters
Does that error still occur after fixing that missing space?

Yes, I´m afraid.

Can you copy and past each of those lines one at a time to the gcode console? The offending line should produce the bad model parameters error.

I got it. This is the one and only line that sends the error message.M307 H0 B1 S120 ;S1.00 ; enable bang-bang mode for the bed heater and set PWM limit
Error: M307: bad model parameters -

M307 H0 B1 S120
Ah yes, ok. It's the S120 that is invalid.
That should be S1. It's specifying the PWM power factor in a range from 0.0 to 1.0, not a temperature.
Once that is solved I suggest you re-run the PID tuning process and save the new values with M500 so that it gets written to config-override.g.
M303 H0 S60 will tune the bed heater to 60c
M500 to save the results
M303 T0 S220 will tune the hot end heater to 220c
M500 after to save the resultsAnd make sure you have added M501 at the end of config.g so that config-override.g gets loaded at startup.

Thanks for this day, I´ll be back tomorrow. -

I comleted the PID tunig. . First I tried M500 but something happened and it did no saving. However in the console there were new lines which I copied to config.g. OK? Seems to work. Looks good now, many thanks. Next thing is to connect the extrusion cooling fans and the second extruder.
config.g:
M307 H0 B0 R0.078 C877.1 D17.57 S1.00 V23.6
M307 H1 B0 R2.016 C174.8:173.5 D4.45 S1.00 V24.0
config-override has same lines:
; Heater model parameters
M307 H0 R0.078 C877.100:877.100 D17.57 S1.00 V23.6 B0 I0
M307 H1 R2.016 C174.800:173.500 D4.45 S1.00 V24.0 B0 I0

The config-override.g having the same lines means that it did in fact save correctly.
