Question #: 6817

Question: on the parallel breakout board I have, there are two 5v inputs on the limit swith side and no ground label. https://www.dropbox.com/s/hxeojviveteqq2f/IMG_7947.jpeg?dl=0 I have used an external ground for now but I am getting random limit and e-stop triggers. please advise

Current Solution

That was one of our older models, which we did not have any specific ground pins on our board, they were not added and we currently updated our board to include them.

For the random triggers for the limits and e-stop, we recommend having these wired separate from any other wires (communication, power, etc), and we recommend shielded cable as well! These will be very sensitive to noise and any interference that might be present.
