General Mach Discussion / Re: Mach 3 keeps freezing
« on: September 13, 2017, 08:31:30 AM »
I have had the same issue. I have USB SS and 5 meter USB cable. Additionally I have 2 spindles with 2 VFD running same time. Without any preventive action I could run 4 or 5 minutes then mach3 was freezing . After reading your recommendations I put 2 ferrites to both ends of USB cable. It helped. Frequency of random stops is decreased but didn't solve completely. Then I have ground my machine. I t didn't help at all. I have put another wire shorting to machine chasis and shell of USB input cable of SS. There is no freezing at all now. I can run at 4 khz setting. ( due to my pc can't meet demands I have dropped it to 1 khz later) At beginning I can't go over 500 mhz. I hope this will help the people facing same problem.
