I will use the limit switches with inductive sensors. I have put a optocoupler board as a level shifter between sensors and input pins.
But when sensors triggers, the voltage drops to 2.3 volt. I am using grbl 5x. Is there a software solution or I have to remove Pull Up Resistors on the board?
If I must desolder the Pull Up Resistors of the limit switches can you give me the names of the resistors.
My board is "MKS GEN L 2.1".
