Hi everyone! I am trying to control the spindle through a Mach3 USB STB4100 card, but I am not able to find the correct wiring and feel completely stuck. After I have made a research, this is the way I connected it but still doesn't work.
DAC (card) wired to AVI (VDF)
COM (card) wired to COM (VDF)
O1 (card) wired to X1 (VDF)
Here is my doubt:
1. Do I need an external relay to switch the spindle on/off? In case I do, how should I wire it?
As you can see, I am quite a beginner but I promise I learn fast!! Thanks for your help!!!
