both the grinders work once or twice then stop.... it opens like its going to normally but the rover no longer displays the option to unload. also the rover display stopped turning red and saying wrong way when going the wrong way... i have checked and even changed out the circuit boards in both i have even incread the power to the big grinder and same issue. i have a trailer full of rock material sitting and waiting and i cant print anything anymore due to no more material
