I Problem to print Gcode on CNC

Hello everyone. My name is Rodrigo and I am building a cnc printer. I am using the arduino mega 2560 with a ramps 1.4 and the repeater firmware. I configure the repeater host to print as cnc and activate it with the command M453, open a Gcode file and print. But when you print it only goes one way over the bed and the z-axis doesn't go down. Then return to the origin and stop printing. Does anyone know how to solve this problem?
Thanks and sorry for the spelling I did it with a translato


  • G1 S1
    makes the firmware accept any coordinates also negative. This enables the default checks we use in 3d printers to prevent illegal moves.
  • Thank you very much, I was able to solve the problem
