Reverse X and Y axes

Hello,

NEJE MASTER 2S PLUS

I just noticed that the LIMIT SWITCH of the Y axis was on the motherboard. So I can’t reverse the wiring.
So I only have to change the motherboard settings to reverse X and Y. I can change the GRBL settings but not the card settings.
I therefore ask you to intervene with the service concerned or to provide me with the address of this service that I can write …
Thank you

Дело не в концевике, а в начале отсчёта по оси Y. (Вместо 0 установлено 420). У меня та же проблема. 2s Plus. Как это поправить неясно.
