how to use limit switch with inductive sensor #11

Open futurau opened 2 years ago

futurau commented 2 years ago

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".
