this is esp32 code, update this and remove unessery things
make it a production code, no memory leak or CPU slow or blocking make everything nonblocking

i need these functions only

1- make function named All_Steppers_Default()
to make all steppers motor back to 0 using limit switch for each motor has its limit switch HIGH = limit is pushed.

and also run this function each time esp32 power on to know all 0 for all motors
note: this function should work perfect all steppers motors back to 0 together parallel also make sure all steppers stop when each own switch limit hit HIGH

save each MOTOR position in mm as variable like CNC to can move it

2- make 5 functions for 5 motors each function taking position to move there like move CAM motor to position 55mm
also make sure to add limits for each motor min =0mm (in limit switch) and max = 150mm

3- make 5 functions for 5 motors each function run move motor 10mm and care about limits that talked to point 2 same limits

this functions take direction so for example Move_CAM(true) move right , false move left and they move 10mm ( that variable is in top of code configration)

4- add emergency stop so when pass STOP in serial that all motors stop

so add processCommand to testing all commands

note: make it as production level no errors bugs crashes slows..etc

Q: For homing (function 1), should the motor speed during the search-for-limit move be the max speed (index 10) or the slower search speed (index 8) from the original code?

A: Max speed (faster homing)

Q: Your point 2 says move-to-position functions, and point 3 says move-10mm-relative functions with a direction bool. Should both function sets run at a single fixed speed, or should they also take a speed argument?

A: Fixed speed only (simpler, matches your described signatures exactly)

Q: The original had a CAM/REL collision check (REL position must stay >= CAM position). Keep that safety check in the new code?

A: Yes, keep the collision check

i need only edited motors.ino full production level
