Check safety door issues

Hi

I’m having a issue with gsender and SLB-EXT safety door error.
I was going to probe, but did’nt reach the probe, when the check safety door came on.
I can not get rid of it, with e-stop button, soft reset or reboot of controller.

All cables plugs is where they should be and can’t find error on cables.
I can’t write command to the controller and a reflash of lateste firmware did’nt do it, I had to do alternative DFU on the pins on the controller.

Does any have a clue, I can’t come on any i haven’t tried.
Documentation and Google search did’nt do it.

Edit: Scienci had a solution, it was to shorten to pins on the door output on the controller.
Haven’t got a answer to why it suddenly inverted that setting, yet.
