I´m retrofitting an old CNC-machine for wood with a bunch of spindles on a big vertical wheel of which each spindle has a different combination of cams and switches so that it can find the right spindle.
So, I wonder if its possible to do this in Mach3, for the programming its not a problem but can Mach3 time it reliable? (with the Ethernet smoothstepper)
I have tried before to stop a spindle when hitting an inductive switch but it was stopped sometimes directly and sometime it took a second or two from the switch was triggered until Mach3 turned it off so that did not work very well.
Has anyone managed this or do I need a PLC to make it work?
Would Mach4 work better than Mach3 for this?
Thanks.

It would depend on what teh signaling requirements would be for teh device(spindleselection) Normally THAT would be controlled from a PLC and then teh PLC and Mach3 would talk to confirm actions.

Well there is no PLC there now so I will control the valves and motors either via Mach3 or a PLC.
So the question is how fast can Mach3 process a input in a macro and stop the spindle?
I would say that it has 0.5s or so to react.
And then there is the Smoothstepper in between...

NOT NEAR fast enough doing it the way you are thinking of . The smoothstepper is not your friend either in this case (;-)
