hi, I'm building a 3D printer , for that I'm using for the electronics part Arduino Mega with ramps v1.4 and a4988 , and two motors-M49SP-2K for X and Y axes and QH4-4325 MOTOR FOR Z axe , I've tried to use the GRBL with ugs software but nothig happned , the grbl worked well but the motors didn't m…

Test the motors (one at a time) with this Simple Stepper Code . You will need to make sure it refers to the correct pins for step and direction for each motor. I think with the RAMPS shield you will also need to set the enable pin - I can never remember whether it should be high or low. It will be …

I think that I found the problem where it is. If you see to the to version of A4988 the mine and the other one where from I got the circuit There is à deference between the pins of GND
