So, I tried everything I know... used different servos, used different pins, mirrored the right and left side and turn front to back.
And as Robot Dude wrote, it might be in relation to futaba copies this doesn't matter because I ordered 3 different packages from different dealers to get all 18. And of these servos, there are 5 feet working well...
So at least, I wanna try to reverse all 3 servos. And as KM6VV wrote to try the "(3000 - position)", I just wanna know now, where I have to put this in the code?
I just wanna see it walk. No balancing, no special walking gaits for now, just simple walking

P.S. the hexapod is mechanically done. Now,I just have to program it...
