Ok. I've been having this problem for some time now, I've been searching the internet for the solution but I cannot find it.
My Knowledge is Limited, but my troubleshooting ability has definitely gone up since I ran into a wall!
So when I Load GRBL onto my Arduino, I know that Pin 13 is supposed to control the EN leg on my pololu Stepper Drivers
What I would like is for someone else to try this and tell me their results.
Attached is a picture of my circuit.
Arduino GND to GND rail
Arduino 5V to 5V Rail
10k Resistor to 5V
D13 - 10k Resistor
For the Drivers to work I know that the EN leg has to go to 0V
I can Send G Code through Universal GCode sender. That works. And I can easily look @ settings and other things. Computer says I'm connected.
Measuring D13 shows 4.92V with the above circuit
The Drivers will engage the Stepper motors when the EN leg reaches 0V
I can't get 0V on D13!!!!!!
What am I doing wrong?
Please Somebody please help me!
Thanks
