The same when it didn't engrave, 23.1V.

Also, what kind of meter are you using - analog or digital?
Digtal multimeter setted on 200V CC.

This (the 23.1V) tells us that your controller is not attempting to turn on the "Wind". This could be due to software or it could be due to a damaged controller. The important information is that this is not an issue with the solenoid or anything else connected to the controller. (It does not mean that the solenoid is good or bad, just that you have a problem BEFORE the solenoid.)

Your goal should be to leave the 4.7K resistor in place, and the volt meter, and see if you can get use software to get it to read approximately 0 Volts.
If you cannot, then you will need to change the controller.

Best of luck!

Thank you, you have been very kind.
Unfortunately I fear the controller is damaged, because initially the behavior was different (at the start of the machine before the engraving the value was 0). :(
