Not a lot to go on, you set the end stop,,post the config.h file assuming you using marlin.

Hi Waitaki,

Thanks for your response. Actually all the motors running one direction.

If your endstops are not configured correctly the motors can do that but are you saying the same happens with the extruder motor too?

I had the same problem bro, you should take a look at the config.h file, because some firmwares like Marlin do invert the logic of the endstops by default. If all of them are "true" in the config.h file, you should put them on false. After that, go to Pronterface, connect your printer, and when you have it online, while you keep any endstop pressed, you send the M119 command, which will send you back the endstops readings. Then, your motors should me moving on two directions
