Hello folks!
This is my first post, though I've been reading for the past six months as much pertinent material as possible on CNCZone (and other sites) in an effort to anticipate the many pitfalls associated with CNC electronics.
I am an absolute newbie but I feel I'm at the point where I am competent to build my own wood router. So I did, and I am now ready to finish the electronics as I have one motor turning, e-stop working, homing/limit switches operational, and spindle on-off controlled per Mach3.
I got all of the above working, however, by switching to a connection scheme that tells me I really don't understand the relationship between the components.
When I connect the NC e-stop and NC (in series) limit switches using pins 9, 4 (respectively) to 5V as on page 4-2 of the C25 manual they work.
But I cannot make any switches work using the wiring configuration on page 4-3 regardless of high or low active settings in Mach3?
Could you folks help me understand why not?
The attached drawing is how my control board actually looks (except for modified e-stop & limit wiring as explained). All signal wires are shielded, elevated for distance, and cross noisy wires at 90deg. as much as possible.
I also include the C25 BOB manual.
Thank you.
Jules
