My New RDC6445G (EC) controller is installed and working but, when I power off and then power on (minutes , hours or days later) the settings revert back to default settings ie. x = 10000 mm / y = 10000 mm / z = 3000 mm .
I rewrite my actual settings for my machine 700 mm x 500 mm back via RDWORKS same issue .
I try with LightBurn write settings for 700 mm x 500 mm same issue ?
same result cannot get controller to retain settings written to it .
Howto get them to be retained ? HELP Please

The x + y will be 10000 til you home them to the homing switches.

tried that but every time the power is cycled I have to hit escape head crashes if i don't,
controller reverts back to 10000 x 10000 x3000 it is like starting all over with the wrong settings.
I've put rhe original 6442 controller back in and all is fine. , and yes I used the settings from the 6442 (manually entered)not firmware,with the 6445
and same issue. Controller Falure .

The 10000mm x & y are positions, not dimensions. The controller doesn't know where the 0 position is for at least one axis, so it sets the x & y coordinates to 10000 so that you can use it without any chance of the coordinates going below 0.

It seems the 6445 is not seeing a limit switch when the startup sequence happens, so the head crashes into the side. I think we can rule out the usual faulty wiring or switch problems, since the 6442 works.

Does the head travel towards the same corner at reset with both controllers?

All Limit Sensors are working .
reason being ,
I changed the controller & HMI back to the 6442
all connections are plug and play.
everything works .

Sorry,
yes ,
both do.
it's set to top left

I Did not and have not pushed the reset button on either controller .
just to be clear .
