Hi I need help. I finished assembling the cbeam and i am using a grbl board. Now that I have gotten to the part in the 2 hour video that tells you to test the jogging of the machine, i have tried it and nothing happens. I know they are getting power because the light is on. But nothing. please help ill send a couple of screen shots that show my grbl settings and interface. I did notice that some of the lines from the grbl settings are missing as shown from the openbuilds example image. $14 Then I have $30, $31, and $32 and the openbuilds example doesn't not sure if that matters but please help.
