SmoothStepper USB / Ess and cnc4pc npn prox wiring.

« on: November 20, 2013, 06:30:36 PM »

Hello. I have an ess and a c25 bob. I have some npn prox switches. These switches run off 12v. I understand that im supposed to put a 10k resistor from +12v to signal pin to pull it high according to the c25 docs. My concern is that this puts +12v to the pin. Am i missing something? I thought you could only put 5v to an input pin. I though the 10k resistor was supposed to cut 12v to 5v but when i test from the resistor to ground i still get 12.31v. Can you shed any light on this?

Thanks for the help I'm at work right now. If you look at the cad drawing I attached and zoom extents, down in the lower right hand corner you will see a pictue of the smoothstepper and bob. It will show you exactly how everything is wired. I hope that will help clear up the ganging thing. The only thing they are ganged to is power. they are each on their own circuits. Y and A are slaved but each has it's own limit switch.so when I home Y it will touch the switch for Y and backoff then touch the A and back off. Does that mean I need to change the option home slave with master?

ok with the ganging all switches are on there own circuit. they all share a single 5v power pin on the c25 bob with the return wire to port 2 pin 10-13. 10 x , 11 a, 12 y, 13 z.  they are mechanical lever switches wired as normally closed.

Ok the results are in. X worked one time in the version you asked me to try. Z still no love! I did a fresh install in a temp directory and then setup only movement and switches. Y and A still work as expected. I have all the switches ganged to one 5v pin for power all soldered to a #14 solid wire. the other ends are put to the input pins. they are active low. Just incase any of this makes a difference. I'll attach a picture in another post of just the smoothstepper and c25 bob.
