I ran a trial today on advice of the forums top diagnostician, @CrazyCasey 
I am regularly having problems with FCtrl freezing during cutting. Typically, my program keeps running, but all display and screen controls lock up until 5-10 seconds after the cutting has stopped.
So, on his advice I isolated my work piece from the slats and ran a 800 line program. No freeze up!
Now, I need to run several larger programs when I have more time in order to know for sure this is a “cure”. Then, I will figure best way to isolate. Maybe remove tray and place rubber strips between tray and table…?
I know I read in your thread about a separate, dedicated. ground to the table. Might try that first (easier).
