It sounds like either the belt has lost some tension and or a coupler has gotten loose. I'd recommend re-tensioning the belt and checking to make sure all your coupler set screws are tight. It might also be a good time to check everything else out to make sure no other screws, belts or couplers are loose.

I will check my belt this weekend since is the only time i have but so far the couplers are good because y have a mark that i know if they got loose ty i hope is the belt i keep posted this weekend ty |

Do the motors sound like they are grinding? If you hear this then the motors are losing steps. This is usually caused by something binding mechanically. Something lose or rubbing? You can check the movement with everything powered down.
Be careful moving the motors by hand. This can cause the motor to create a voltage and back feed into the stepper driver and damage it. Move them slow by hand to avoid this damage to the drivers.

Ok i have the belts tight and i run the program again and looks good but very a the end i have again missing steps i don't think is the drivers i hope not .. what i know is something on the x axis because that's where i notice like the motor struggle to push the router sideways ,but is weird because is was just at the end, next weekend im gonna thigh the belt again is all i thing is the problem because everything works good also can be the debris since i was cutting PVC and maybe are some debris inside the belt tooth and wheel that make a no good contact between the wheel and belt thanks for the help |

Since i see many people have always problems with stepdrivers and motors do you thing is a good idea to have extra step drivers and motor or even a uno board with cnc shield? Just saying better be prepared since this is gonna be my work machine and normally i works for hours like 6 to 8 cnc hours every day on weekends (Saturdays , Sundays) after november i have the money for my mega v and i hope working a full week now on both machines ...
Or what normally i should buy for maintenance on m3 cnc??

Make sure you are using good endmills that are sharp. Dull endmills can make cutting difficult and may be a cause of losing step position.
Spare parts are good to have on hand if you have critical schedule demands.
I would say spare belts and stepper drivers would be good to have on hand. But keeping you machine clean and using some dry lube on the bearings and slide rails goes a long way keeping your machine running also.
It would be up to you if you think you need a spare motors and Uno/CNC Shield boards.

The stepper drivers will probably need to be setup with the correct voltage setting (current limit)
The M3 assembly manual has the setup instructions for this setup of the stepper drivers.

I think the M3 has two sets of holes to screw the mount into. You can use either set upper or lower.
