Cnc usb controller connecting controller to drivers

Controller detects this and asks for retry. But in bad conditions many errors get through anyway. This means a lot of big packets at high speed. Grounding is major issue.Д¬NC controller is very intense USB device. USB is not galvanically isolated like Ethernet. USB uses differential signals which are more resistant to noise but main problem is power. USB works well with the scanner and printer, intervuys USB is sure to work with all devices.Дo you have any ideas other than replacing the computer and cable?Д®lectrical interference causes errors in USB transmissions. I completely rule out problems with noise and power leads or a problem with jamming. The second machine always performs the 'HOME' procedure and you can manually burn the axes.Д«ut it always stops with the message 'Controller Disconnected' when performing the first G1 movement in the program.ДЄt the same time, this situation does not envy the operation of power supplies drivers, motors, spindles and other power devices - the problem is only in the connection between the computer and the controller. I can continue working from any line of code. There are no error messages, the spindle is switched off, cooling is still enabled. The first machine works well, but can sometimes stop 2-3 times a day in the middle of the program. USB wire shielded with two ferrite filters 1.2 meters long. I have two CNC machines with USB controllers Mk3/4 (3 axis)ДЄll equipment is the same-computers, drivers, motors, wires, power supplies.
