When you say the motors are kicking out, do you mean physically out of the rail and jumping or do you mean the system estops and the dro's turn gray? If the system is e-stopping, try unchecking the "stop on lost arc" button below the torch volts dro. I put in some special capacitors at the master motor mount but still have the same problem. Un checking it eliminated the estops but the machine does keep running when you have a real lost arc, which is not very often. The machine will pick up the cut easily enough if that happens. One thing we learned about restarts is to make a circle in at least two arcs if you suspect a problem ahead, as the system will not pickup the cut if it is a circle and you have to go back to the start of the circle cut and run w/o the torch and manually click on the torch fire button when you cross the lost cut area and run for a few inches before turning on the thc. I should add "large circles" over a few inches in diameter, as bolt holes are usually not a problem.
