Hi guys, I'm working on the control panel for my cnc 4 axis router (2nd x axis to be slaved). I will be running a 24v safety system and within this will be 2x e-stops, limits and home switches.
When triggered the 24v system will cut power to the 70v supply to the steppers but I'm confused how the triggering item I.e. e-stop will communicate to the bob to show Mach 3 what has caused the stop if wired in series as surely any item within the parallel wiring loop could be seen as the cause? Or is this the case, Mach just sees a fault and its down to the operator to find the cause?
Are relays typically used from the 24v system to send the control signal to the 5v break out board inputs?
I am working on a diagram for my system which could do with being looked over by someone that knows what they are talking about, should have this posted mid next week if you could comment. I have seen loads of diagrams of set ups but want to draw one for my system to get it clear in my head as this side of it is not my strong point. Cheers.
