I am running Centipede with Mach3, Granite VSD-e servos. Twice on power up, I have had runaway axis. Please tell me how to fix this. Everything is plugged in to a power chord. The servos have HV Power when I plug it in, while I am not booted to Mach3. The Estop is engaged, but evidently has no effect until Mach3 is booted, is that true? Shouldn't I power up the computer, then boot Mach3, then plug in the HV power for the servos? Or have three relays to engage the servos, this is a dangerous situation. Please help. Bob.
