CNC Homing Answered
I work on CNC Alamode project, raspberry pi and Alamode is configured to control 3 stepper motors: My configuration: Raspberry Pi Alamode (Arduino compatible), 3 stepper motors and 3 EasyDriver.
Everything works, grbl is ok.
Here is my story:
I wanted to install a homing system, I first started with the x axis, as in the drawing, it worked well, it has stopped the motor, but I realized that the current 5v passed directly on Limit X (D9), without 330 Ohm resistance.
Then I put this resistor like a drawing but now the homing no longer works.
My question is: Have I damaged my card, knowing that everything works?
Can I redo my original configuration without resistance?
My last statement : 4.96 Volts between limit x (D9) and Ground.
Thank you for your help.
