It's a pity my Milltronics is so old and I don't want to learn but it would blow most controllers away, Hurco is is the same. Milltronics is conversational and G code, it has graphics, you can can draw a circle then draw a line in close proximity to the tangent point and it will snap it on to the circle and then you can that on the fly and just keep going.
For $2000. they upgrade the control, just don't know which way I should go, Have nice Fagor 8035, Fanuc 0 controls sitting here on the floor, or Mach3, EMC2....My feed hold works great now, they make is slow down because of the steppers I guess, I'm on servos and pulse coders and can stop on a dime. Yes the stop function shouldn't even be next to the feed hold, should be removed and should reset like any other machine.
