Hello,
My name is Neri while I am not a completely clueless in electronics I have some beginner level knowledge. I would like to have an LED indicator driven from the STEP output of my CNC controller so I will have visual feedback of axis movement I have tried some NE555 pulseting logic probe based circuites while they worked to some extand I never got enough lumination (brightness) from the LED and the results were far from what I needed. Then I have tried some Opamps circuites but with no success. The STEP port reading is averaging 0.25V fluctuating, the DIRECTION port reading is 4.85V
I was wondering if anyone has an idea or schematics that can accomplish this task, it should support 3 LEDs from 3 different pulse input(X, Y, Z axis) I just want the LED to detect the pulse
Please help
