hi wonder if there is anyone that had this problems in past
what is happening is when i turn my 3d machine with USB to my labtop my labtop mouse pad just by toutching it moves alone all over and opens windows etc..
bt if i use a wireless mouse then doenst happen, so this have something to do with the USB conection to the 3D printer, if nothing connect then works perfect
is there anyway to solve this problem

thanks

Try running your Laptop on Battery - without Powercord, and see if Problem persists.
If solved, might be some kind of ground loop.
Try to Power your printer and Laptop from the same socket, Maybe (if possible) turn Powerplug of Laptop 180° to exchange Line and Neutral.

If problem still persists - I do not have another clue.
