I use Openbuilds controller. Normally when I open my g-code and I run it, my router will start too. But today it worked very well on the first time thereafter I opened a new G-code and job run but the router doesn't start. I closed everything and restarted again and the problem is still there. When I click on the icons on and off, the router starts and stops without any problems. Do you have any idea what the problem is? Thank you for you held.
Good, so hardware and Grbl settings check out Then the issue must just be that your GCODE doesnt contain router on/off commands or the command is incorrect (too low, or not included S values)
