I am running Mach 3 on a mill. After having had many problems with false limit switch triggering I have now disconnected the limit switches from mach 3 control and have them now operating at 35 volt DC (power supply voltage) a relay which disconnects the DC power to the BOB on the event of E switch or limit switch operation. This system appears to function well but it would be preferable if in the event of a switch tripping it would also stop Mach 3 at the same time.
Could anyone advise me if this is possible and the way to do it?
