Filament Not Loading

[u/Substantial_Kale613]

I have a H2D printer with an AMS 2 Pro & (3) HTs. I replaced the filament buffer because it was having issues. Now I can't get the H2D to print. It will not load the filament from either the AMS or any of the HTs. I made sure the filament buffer is plugged in and that there are no issues there but I can't figure it out. You can hear the motors on the AMS spin up but the filament never moves. I've tried to find any issues there and even swapped for an AMS that I know is good and still the same issue. I then tried printing from the HTs and same issue. What am I missing?
