Found a "home made hax" for reparing M6 that way (they have way too much hull you will die of boredom before you repair it, and that doesn't take into account bigger ships). Exit the ship, target the mouse get a coffee/tea mug, place it on your fire mouse button so that the mouse doesn't move but the laser fires.
Go do something else for a little bit and when you are back your ship is in top notch condition![]()
the left ctrl button is also a fire button, much easier to put something heavy on that.
