Hi, i'm having some problems with my custom made machining center. It's has a nice precision of 0.008mm, built on grounded ballscrews and some other stuff.
But there is something that upset me, it's build around MACH 3 and has no feedback, it uses servos on their own closed loop system, but the controller has no feedback.
So about the thing... when i press the ESTOP button or i suddenly stop a program, my machine loses reference, not much, something like 0.2 or 0.1mm,
but for me it's a big ideal, i spent some real money on the construction, used some nice techniques to keep the precision and i want to make full use of it.
My theory is that when i press ESTOP, i stop MACH3, MACH3 then sends signals for the servos to stop, but this has some delay, maybe due to the controller board i'm using
or even the reaction time between COMPUTER, CONTROLLER BOARD, SERVO DRIVE and the MOTOR.
So now to the fix, i was thinking about physical linking the ESTOP button to the servo drive, it has so many functions, have anyone here done that ? I think it will improve reaction time.
Or anyone have another workaround ?
