Well, I think this C23 is under demonic possession. One relay seems to be dead while the other refuses to take commands. I then noticed that while running the spindle motor the pin 14 LED was illuminating weakly. While messing with the board earlier I thought I caught a glimpse of an LED lighting but assumed it was glare. Pin 14 is set to spindle motor step/analog output and since I could control the VFD I figured, in this configuration the LED was out of the loop. I thought "cool" the LED lights...yay. I then found that all 3 axis outputs were dead and I had no control of the analog/VFD speed as it was maxed out. I swapped out the chip set to see if one had gone belly up with no change.
I'm giving up on this board. I just ordered a C11... I can ruin that at half the cost of the C23
For the C23, do I use a shaman, big hammer or the tried and true Sharps 45-110?
