Hi all, I picked up a novusun NVCMV2.1 breakout board and am trying to setup my home/limit sensors. I have input 1 as estop(default) and input 2 works as either home or limit. I cannot get any other input to work. I install my proximity sensor and it lights up but doesn't send a signal to mach3. so input 3 to 9 and in10 to 16 do nothing. am I missing something? Thanks.
