multiple error codes, now bed knocking

yesterday, I started having CZ2581, CZ2761, CM2781, and CF0109 codes pop up, when starting a print or from a boot up. This morning when I booted it up, the print bed, in the bottom-home position, started banging and shuddering. Some of these codes I can’t locate in the official list. I am thinking I may have a controller board issue, since there are so many different ones. Man, I was just loving this printer until this happened. Now I’m dead in the water.
Any help would be appreciated.
