MKS GEN_L is a powerful 3D printer control board with ATMEGA2560 and compatible with RAMPS. V2.1 version the motherboard integrates SPI / UART interface and works with MKS TMC2130/TMC2208 V2.0/TMC2209. It can be used after plugged in. No soldering or flying lead is required ...
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".
