Re: Red "fault" light is lighting on my G540.
loose connections can easily cause damage to stepper drivers
when energised
the breaking of any motor connection will result in a back emf in the disconnected coil that is many times the supply voltage -
destroying the output transistors that control the current that flows through the motor coils

OK, I understand!
So maybe it will be better to solder the wires from the drivers directly to the stepper wires instead of using a plug in that area in order to prevent damages like that?

Re: Red "fault" light is lighting on my G540.
I tried another time with a new driver and this time the same happened when I turned the tuning potmeter all the way to one end in order to get rid of the ticking noise, so I believe it was the same that happened last time. Does this potmeter regulate the current or voltage in a way that can damage the driver?

I have the old version without plastic body. Do you know which components it is which has been damaged? It will then be much cheaper to change some components than a whole driver.

Re: Red "fault" light is lighting on my G540.
unfortunately I don't have any component level details of the Gecko stepper drivers
Its a question you will have to ask Marris at Geckodrive.com
