Hello, my VG-L7 now has a grbl controler which I have changed for another as there was a fault, the laser did not light up.
Now I have another problem as soon as I switch power to the L7 the x and y motors sieze solid, switch off and they are free again to move. Has anyone any ideas of what could be the fault. Whether the pc is connected or not thios fault occurs. Previously they had functioned OK.
Have you tried changing $4?
