I build DIY cnc using clone Chinese arduino, every think is good at first, but wait no axis move now, and get the error try to reupload In file included from C:\Users\acc\Documents\Arduino\libraries\grbl/config.h:30:0, from C:\Users\acc\AppData\Local\Temp\arduino_modified_sketch_71775\grblUpload.ino:1: C:\Users\acc\Documents\Arduino\libraries\grbl/grbl.h:68:4: error: #error "Required HOMING_CYCLE_0 not defined." #error "Required HOMING_CYCLE_0 not defined." ^ C:\Users\acc\Documents\Arduino\libraries\grbl/grbl.h:108:4: error: #error "WCO refresh must be greater than one." #error "WCO refresh must be greater than one." ^ C:\Users\acc\Documents\Arduino\libraries\grbl/grbl.h:111:4: error: #error "Override refresh must be greater than zero." #error "Override refresh must be greater than zero." ^ Multiple libraries were found for "config.h" Used: C:\Users\acc\Documents\Arduino\libraries\grbl Not used: C:\Program Files (x86)\Arduino\libraries\grbl Not used: C:\Program Files (x86)\Arduino\libraries\grbl Not used: C:\Program Files (x86)\Arduino\libraries\grbl Not used: C:\Program Files (x86)\Arduino\libraries\grbl exit status 1 Error compiling for board Arduino/Genuino Uno.

what error? the one you copied below or some other error? First fix that, you removed or commented the homing cycle define and it NEEDS it in config.h.
Mr david I am just asking how to fix it in detail , I am not expert as you think me , And this cause no axis move ?
You have bad firmware and nothing will work until you find and load good firmware. What firmware are you trying to use and where did you get it. To get help you need to give the details of what you are doing.
you are getting the home cycle error because *you* changed something in config.h you need to go back to a fresh copy of GRBL without any changes and load that into the arduino and make sure the machine works with that before you make any changes. in fact you should not even try to enable the homing cycle before you have a working machine that moves correctly = correct direction and correct distances.
Thanx a lot I compared the config.h uploaded to my arduino and fresh one , Its different in some define . But after I succeed to upload the grbl to arduino , I still got nothing to move , I used my multimeter to read arduino pins when I move x axis on UGS ( not moving on actual ) I got 0.001 reading on step pulse pin and some time 0 , this on pin 2 And on direction pin i got non stable 5v and 0 v but not stable some time I read only 0 v this on pin 5 And 5 volts when stop and 0 volts when moving by ugs on enable pin , pin 8 Is this caused by config.h too , or another problem
