There is no tutorial, but if Aze is reading this post, maybe he would send you a copy of his firmware

You open the online configurator:
https://www.repetier.com/firmware/v100/

you can upload my configuration.h to have a starting point (attached piece).
Then you need to change the steps/mm with your actual values (look into your configuration.h from Marlin).
Try not to put more than 1/8 of microstepping on your drivers, it's more than enough (precision is 0.016mm in X & Y with 1/8 of microstepping and even better in Z). Marlin is skipping steps because it can not calculate fast enough. Repetier won't miss steps, but can be laggy if you use more than 1/8 on your drivers.

Hi,
I have uploaded the repetier firmware instead of Marlin, but I can not see anything on the display. If I connect Repetier host the Nema work properly.... What should I do?
Thanks

I don't have the same LCD screen, choose "full graphic LCD" in the parameters. Sorry I forgot to tell you.

go back to the online configurator, and change the screen.
Then go back to your Arduino IDE, go to examples->eeprom->eepromclear() (load it once, to clear all the EEPROM).
Then compile and load your new Repetier Firmware.

ok. thank you. I have the settings of the LCD screen and now it works.
I saw that the display and information are different than Marlin ... can you explain how do you set the zero point of z and how do you set a home starting?

Just press the reset button to make a (0;0;0). I don't know your configuration: in my case, only the pin ENA is connected on my board (=if the CNC is ON, I can not move manually X and Y, but if I disable the motors with the screen, only the Z will be disabled and I can move it manually to make my zero on Z).
